Bicycle Botany: Road Marbles, Part One


In case you haven’t noticed, I haven’t blogged much about cycling lately. This is due to what boils down to one reason really; I haven’t spent much time on my bike lately! Actually, that is not true, I have spent a lot of time on my bike, just not outdoors.

I’m still having some issues with keeping my hands and feet warm so the idea of heading out on my bike lately has been a difficult issue do deal with. I have been riding my trainer in the basement of our house a great deal (there is Zippy to the left). Which has been working out fine. I don’t know about anyone else, but I really do get an excellent workout on that silly thing. It’s just not a whole lot of fun.

It was about this time last year I started having issues with fatigue, numbness in my toes and various and sundry other stuff that effected my ability, or desire, to ride my bike. I had a blood test done which showed that I had extremely low levels of vitamin D. Normal is between 30 and 100. Mine was 7! My response to hearing this was that 19 years of living in the Pacific Northwest finally caught up to me! Hummmm, sink me.

So, to make up for this I took massive doses of vitamin D and things were dandy...or so I thought. Now, a year later, I just got another blood test. The results were good in that my vitamin D levels are higher, all the way up to a 15! So I’ve still got some work to do there. In addition, I also learned that my vitamin B-12 levels are low. Normal is 200-1000. Mime is 230. So, starting tomorrow, I’ll be getting shots to boost that. Hopefully, that will bring back some of the feeling in my toes. Either way, I’ll be back out on the open road soon! You’ll see.

That’s all good and fine, however, low vitamin levels are a metaphorical road marble that have kept me from riding much lately. They are not the type of road marbles I was thinking about for this blog post. I was thinking about real road marbles. The ones that can actually be a real hazard here in Pennsylvania if you are on your bike. Anyone who rides here probably knows what I am talking about.

What are these road marbles you ask? Road marbles are green and range in size between a racket ball and a soft ball. They come in two types, the smooth smaller type with a fleshy outer layer and very hard center and the nubby fleshy type that are just plain fleshy. Yeah, is said fleshy twice. These road marbles are in fact the fruiting bodies of the black walnut and osage orange trees.  And in the fall they can completely fill the shoulders of the roads around here. I have nearly hit the pavement on more than one occasion after hitting one of these little green spheres.

Black walnuts probably don’t need much explanation. It is a common native tree here in the east. I see them just about everywhere and I think they are quite beautiful (in my humble opinion) and I also think they are one of the trees that define the eastern forest (now that the American chestnut is MIA). The photo to the left is of my parent’s old barn (constructed out of American chestnut) on Fisher Branch near Mars Hill, NC with a walnut tree beside it. While I assume not everyone reading this could pick out a black walnut tree in a tree line up, I would think all most every one was familiar with black walnuts the food item. They are, in fact, yummy. I would expect fewer people to know that the black walnut tree is an important dye for both fabric and wood. Black walnut stain really comes from black walnuts!

My favorite fun fact about black walnut trees is the fact that they are allelopathic. I’m sure you haven’t use the term allelopathy in a while so let me refresh your memory. It is “a biological phenomenon by which an organism produces one or more biochemicals that influence the growth, survival, and reproduction of other.” Got that? Great.

Allelopathic properties are the reason that you plant marigolds in you garden to control nematodes. Marigolds produce a substance known as alpha-terthienyl that kills nematodes at a 100% kill rate. Who knew? Asparagus also produces compounds that control nematodes but they are not quite as showy as Marigolds. Other things like corn pollen can affect the growth rates of other plants. Being able to control the growth rate of your neighbor is a pretty cool trick when it comes to competing for valuable and limited resources.

Black walnuts trees produce a compound called juglone or more specifically 5-hydroxy-1, 4-naphtalenedione. I don’t know about you, but I’m calling it juglone. Like corn pollen, it also allows the walnut tree to inhibit the growth of their neighbors. Which may be a good reason that I see so many of them around.

The problem with so many of them around is that walnut trees are prolific producers of walnuts. They fall to the ground and become road marbles. Something cyclist must stay on their toes (petals, peddle, pedal?) for…

Bicycle Botany: The Kudzu of the North!

Back in Washington State I would occasionally be riding along on my bike when I would smell a particular fragrant plant then have the overwhelming urge to head to a mirco-brewery. The plant that would cause such an urge was Humulus lupulus, or Common Hops. I knew the odor well as we had a Centennial Hops growing in our back yard in Sequim.

Back in the spring I began to see a plant growing on the side of the road that looked very much like hops, but the fragrant smell was absent. I stopped and crushed the leaves to see if it had the distinctive odor and it did, but very faintly, clearly not the hops that I was familiar with back in Sequim. I took a chunk of it home and as it turns out, it was a species of hops, Humulus japonicus, or Japanese Hops.

As the summer has worn on here I have seen more, and more, and more of this stuff creeping along the roadways of southeastern PA. In fact, once I began to hone in on it, I’d notice it taking over whole fields! Instead of invoking pleasant thoughts of heading to a brewery, I began to have nightmare that if I stopped to long on the side of the road I would be swallowed whole by a killer plant. It reminds me of that other invasive vine from Asia – kudzu.

One of the things about the Northeast that I have always liked is that the winters here seem to be to cold for kudzu to thrive like it does down south, but where kudzu leaves off, Japanese hops seems to take over. One thing that is a little reassuring is that Japanese hops dies back completely in the winter, so its ability to cover entire forest is somewhat limited.

According to the USDA there is not much that can be done to control Japanese hops. The best method that I can find is mechanical control which, in the long run, does little to stop its spread.

As a side note, it is one of five members of the Hemp family found in Pennsylvania. According to the Plants of Pennsylvania common hopes and its more infamous cousin marijuana are also found growing wild in the state but in a very limited number of places. The two other members of the family are native. Hackberry (Celtis accidentalis) is found commonly throughout the state and dwarf hackberry (Celtis tenuifolia) is limited to the southeast and southcentral regions.

Plant Identification 101

There is no greater happiness in the known world better than coming home with a plant that you have absolutely no idea as to it’s identity, turning to the front of your 1042 page “Plants of Pennsylvania,” starting with first step on the technical key and 90 seconds later worked your way directly to the correct species. This happens to me about once out of every 32.7 plants I try to identify.

The rest of the attempts end up as an epic struggle with my Flora of Pennsylvania where I spend hours pecking my way through the key ending up on incorrect species after incorrect species. Often times, I can’t even figure out the correct family. At those times I usually refer to my botany book as “Road Block.” Which comes from the fact that the authors are Ann Rhoads and Timothy Block.

If you have never looked at a botanical tome you might think they were of another language and culture altogether. And for the most part, you would be right. These works usually start off with a dichotomous technical key to the families. If you are unfamiliar with a dichotomous key, they are a simple concept where you are presented with two options. You decided which option fits your situation and then move on to the next option. In business and management they are referred to as “decision trees.”

The first two lines of Road Block is this;

A. non-green epiphytes or parasites, or plants lacking normally expanded leaves and/or stems

A. green, not obviously parasites, stems and leaves present

Seems easy enough, right? Well after than all hell usually breaks loose. Sometimes the route to the right plant can have scores of options. One wrong turn and you are sent off to the incorrect part of the plant kingdom. Further, the specialized botanical language alone is enough to make a normal person not so normal. In fact, I have another book to assist me for that called Plant Identification Terminology: An Illustrated Glossary, because words like cleistogamous are not part of my every day lexicon. Cleistogamous, by the way, means a flower that never opens. Who knew?

To make matters more difficult, you must have a dissecting microscope to see many of the plant parts that are used in the keys. In this regard, I am lucky in that I happen to have one of those in the basement. Still with all this highly specialized and precise terminology and advanced optical technology, I can still often come up completely empty.

Not long ago, I came across a shrub at the Stroud Preserve that was unfamiliar to me. It had “wings” on the stems and green flowers. Both of these characteristics are fairly uncommon and conspicuous features and I figured that this plant would fall into the category of species that I quickly identify. I broke off a stem to bring back home to work through the key.

I was wrong. I spent hours trying to figure out to which stupid species this stupid plant belonged. In fact, I felt pretty good in calling it a “stupid shrub” because of the fact that “shrub” was really the only thing about the plant that I knew was a certainty.

I was obviously over looking something as I keyed it out. I checked every fork in the key to make sure that I wasn’t over looking something to no avail. I was clearly overlooking something. Frustrated, I walked away from it and moved on to something else. Later in the evening when I was sitting at my computer I figured why don’t I give Google a try. I typed in “shrub green flowers.” In less than a second, there were scores of images of winged euonymus (Euonymus alatus).

I still chose to refer to it as stupid shrub.

Sap Sucking Parasite!  

For those of you who may not know it I have a special place in my heart for parasites. especially Dipterian (flies) parasites of birds and mammals. I find the ecology of parasites endlessly fascinating.

On one of my bike rides this week I spotted another pretty cool parasite. This one a plant, Conopholis americana, commonly called squaw-root or cancer-root.

 

Conopholis americana, 4 April 2012, Fisher Branch, near Mars Hill, North Carolina.

 

Unlike most other plants C. americana has no chlorophyll and does not require any light whatsoever. It gets everything it needs from the roots of other plants. More specifically, actually, quite specifically, oak trees.

Much to my surprise, it appears that not much is known about the life history of this species. The bulk of the plant is in the form of a gall that is attached to the roots of oak trees. What you see in the photograph is the flower stalks that push up through the ground about 3-8 inches. One of the few studies that I found stated that it appears to be largely autogamous (self-pollination), however, some pollination by insects, such as bumblebees, has been documented. How it's seeds are distributed and how those seed find the roots of oak trees seems to be largely a mystery, although some long distance seed dispersal has been documented through mammals, mostly white-tailed deer.

It is found in eastern North America from Nova Scotia, west to Iowa and Wisconsin and south to Mississippi and northern Florida. In the states of New Hampshire, New York, and Rhode Island it is considered threatened. There is a very similar species C. alpina found in the mountains of New Mexico, Arizona and Texas, which is an obligate parasite to ponderosa pines.

In addition to its interesting life history, I think it just looks pretty darn cool, and so does William.

Riding Grapevine, Stinking Willies, and the Land Speed of a Turkey

This post comes to you in triptych form; bicycle, bicycle botany, and bicycle birding.

Bicycle: Riding Grapevine

The kids and I are spending the week at Grandpa and Grandma's house in the mountains of western North Carolina. They live on Fisher Branch (a branch is a small stream that a healthy Appalachian resident could easily jump over. The key word is healthy. This eliminates 95% of the population of Western North Carolina), which is near the community of Center (a fork in the road), which is near the community of Petersburg (an actual cross road), which is near the town of Mars Hill (a real town), which is about 16 miles north of Asheville, North Carolina. Needless to say, they are up in the hills.

The road that leads from Center to Fisher Branch is Grapevine. Grapevine is a road that is about 7.3 miles long. It runs the length of Grapevine Valley, which is only a few miles long. The rest of Grapevine road goes up and over Walnut Mountain to Big Laurel Road in Big Laurel. Got that? Don't feel bad, I ain't got it either. What's important is that Grapevine road crest Walnut Mountain at approximately 3163' in elevation. When you ride your bike from Fisher Branch to Big Laurel it is a round trip ride of about 14.6 miles with about 2000' of elevation gain (see a map of the route here). It takes about an hour and a half. All in all it is a pretty good workout with some fantastic views. Like this one.

Bicycle Botany: Stinking Willies

On the way up and to the pass on Walnut Mountain the pace is kind of slow. Slow enough that a cyclist can glance over and check out the flowering plants as you go. Coming up on the far side of Walnut Mountain I passed a small stream that was loaded with many different kinds of flowering plants. The most dominant amongst them was a species of Trillium.

 

This is Trillium erectum. Here is a good example of why the use of the scientific name is a good ideal.

Scientific Name: Trillium erectum (L.)

Common Names: Wake Robin, Red Trillium, Purple Trillium, Stinking Trillium, Birthroot, Beth Root, Stinking Benjamin, Stinking Willie, Birth Wort, Nodding Wake-Robin, Bathroot, Bathwort, Bath Lily, Nosebleed Trillium, Ill-sented Trillium, Indian, Shamrock, Squawroot, Lamb's Quarters, Ground Lily, Wood Lily, Daffy Downlily, Jew's Harp Plant, Milk Ipecac, Pariswort, Rattlesnake Root, Bumblebee Root, Truelove, and last but not least, Three-leafed Nightshage.

The reasons that T. erectum has acquired so many common names are many. One reason is because it is a showy plant that is wide spread in eastern North American so many people (other than plant nerds) take notice of it. It is also highly variable, coming in white, red, purple, pink, and rarely yellow and green, leading people to believe that they were different plants. It was also used for medicinal purposes by early midwives and Native American cultures as something that would induce labor or help control hemorrhaging during childbirth. And as some of those names imply, it also smells to high heaven. Like skunk cabbage it is a plant that uses the smell of rotten meat to attached pollinators like flies and beetles. The common names that caught our attention was "stinking willie." When we pointed this out to William he screamed "Oh no! Another reason for Emily to torture me!" Back in Grandpa Gene's yard there was a deep red one blooming. Same species different flavor!

 

As I mentioned above it enjoys a wide distribution through eastern North America. In North Carolina is primarily found the western mountains. It Pennsylvania it is found in almost every county except Chester! So, I'm going to enjoy it while I'm here.

Bicycle Birding: The land speed of a Turkey

Coming down Walnut Mountain may sound like an easy thing. However, it is almost as difficult coming down as it is coming up. The reason is for the winding road, with many hairpin turns and blind curves, that is starting to deteriorate with gravel and sand in the most unwanted places. Going up the workout is with your legs. Coming down it is with your forearms because you are applying the breaks where possible without skidding over the side.

Coming down you always want to make sure you stay in your lane because a car coming up would certainly take you out. Today, I round a curve and found something else to worry about. A male (tom) American Turkey jumped in front of me with on a few feet to spare. I was able to slow down enough as to avoid and negative outcome for both the large dark chicken and cyclist alike.

Once the situation was under control the turkey did the oddest thing in that it ran straight down the road about 10 feet in front of me. We rounded a bend and it kept on running. I laughed out loud (lol) at the way it dashed down the road; a view of a turkey that I have never seen. I glanced down at my speedometer and was impressed that this bird that I always thought of as clumsy and somewhat gangly moved along at a steady 16+ mph! After about 100 yards of this we got to one bend and the turkey simply ran off the edge of the road, spread it's wings and flew up into a tree. I chose not to follow suit, made the turn and continued down the mountainside via the road.

Back in the Saddle

 

Bicycle Botany: Bloodroot (Sanguinaria candaensis L.) blooming on a roadside in Chester County on 26 Mar 2012. 

At long last, I have our new site up and running! On my last post on the old website I stated that I was having some health issues, which included, but was not limited to, joint pains, cramping, extreme fatigue, numb toes, general malaise, to name a few. 

My bike riding was going great up to December then it fell of quite dramatically. Before December I could do 40 mile plus rides and maintain a healthy pace of over 18 mph (a good pace here with all of our rolling hills). Then in December I was struggling to do a 20 mile ride in an hour and 45 minutes. And when I got home from those epic 20 mile rides I was absolutely drop dead exhausted as if I had ridden ten time that many miles. 

My best guess as to what was going on was a tick illness. Back in November I did get a tick bite from an Ixodes tick, the type known to carry Lyme Disease. So, I went to my doctor to get a blood test. The test came back mostly negative (these blood test for Lyme Disease of not very precise). However, what it did show was that I had a severe vitamin D deficiency. Humm....

The doctor said that normal levels of vitamin D in your blood were 33-100. Mine was seven. The doctor said that many of my symptoms could be attributed to low vitamin D. So, they put me on some heavy dosages of vitamins.

This turned things around almost immediately. I have now gone through an eight week course extra D and I'm felling pretty good. Last week I managed to do a 50 mile ride with a 17.5 mph average without any issues as before. So things are looking up!

Another thing that I talked about in one of my last post was my goal of riding my bike on February 29, April 17 and September 23 as they are the only dates on the calendar in which I have never ridden my bike. I have already failed at this. The whole week of February 29 Paddy was home sick and I just wasn't able to jump on my bike at all that day. Oh well. My next chance to close out that date will be in 2016 when I will have a high school senior, high school freshman, and a fifth grader! Holy Mackerel. 

My riding thus far this year is at a much reduced pace with only about 900 miles logged. One reason for this is stuff like the photo above. As spring unfurls in my first east coast spring in tweny years I am seeing many plants that I haven't seen in a long time. When I see a new and interesting plant, I just have to stop and check it out. So you can expect more bicycle botany in future post. 

This one is commonly called bloodroot because of its reddish-orange sap. The genus name Sanquinaria comes from the latin word sanguis which means blood. This is amongst the eariliest blooming wildflowers that I have noticed here. It is also a native plant to North America. Most of the flowering plants that I have seen so far have been introduced. More on that later. 

That's it for now. Ride lots and stop often!
