So far this year I’ve identified 48 species of flowering plants in 21 families.  Currently, the family with the most species is the Brassicaceae (mustard).  It will soon be overtaken by the rose and pea families, and eventually the aster family  (last year, one out of five species I identified was in the aster family).  But for now the brassicas rule.

Here are some of the cresses.  Apologies that most of the pictures are not so clean.  Sometimes I’m in too much of a hurry and just take snapshots of plants to prove that I saw them.

lyre-leaved rock cress (Arabis lyrata):

smooth rock cress (Arabis laevigata):

Pennsylvania bittercress (Cardamine pensylvanica):

hoary bittercress (Cardamine hirsuta), an alien and common lawn weed:

field pennycress, aka peppergrass (Thlaspi arvensi), another alien (the characteristic upper stems leaves not yet open when I took this photo):
