The leader of this band is the oak-leaved Gerardia, 
gay with large yellow flowers. If we mark them at all, 
we see that yellow is a favorite color, for here are at 
least seventeen which display it. Nearly as many are 
robed in white, and not a few are clad in purple or blue. 
What an admirable provision is this by which, 
willingly or unwillingly, we are made to assist Echino- 
spermum and the various species of Bzdens in scattering 
their seeds, as we pick from our clothing the little burs 
which attached themselves to us as we brushed by 
them! The almost transparent stems of the richweed 
furnish excellent material for microscopic study. It is 
abundant in low rich lands, especially in the neighbor- 
hood of barns, where it sometimes crowds out nearly 
every other form of vegetation. Its kinship to the 
nettle is easily recognized on anything more than the 
most superficial observation.
