Yesterday I shared the tracking highlights of my recent walk through south Waterfall Glen Forest Preserve. Today, some winter botany. These are not unusual plants, but such a large area provides a lot of good examples to choose from for photos. The first species is one I haven’t found at Mayslake Forest Preserve, my main area for botanical study.
Someone familiar with this species will recognize it from this photo.
A closer view of the distinctive fruiting stalk reveals it to be lopseed.
Another woodland herbaceous plant, and one of our most common, is the wood avens, also known as white avens.
Again, if you are familiar with this one, this photo is enough.
Close up, the seeds in their loose ball project the hook-like extensions that latch onto fur or clothing for dispersal.
In this case I have a flower photo to show.
Wood avens is in the rose family.
One more common woodland plant, this time beginning with the seed array:
Again, little hooks serve to aid dispersal.
Here is the entire plant, a woodland knotweed.
I’ll close with a weedy plant from the Old World. It grows in the open, and belongs to one of two species. I do not know how to tell them apart without the flowers.
The sprawling, spindly plant form is rather nondescript in winter.
The seeds, many of which have been knocked off at this point in the season, have a vanilla flavor if chewed. I don’t recommend chewing on unfamiliar plants, however.
When blooming it looked either like this:
White sweet clover
Yellow sweet clover
All in all, this was a satisfactory walk even without the spice of bobcat tracks.
