Most of these plants are not uncommon in our range, and this 
habitat 1s less boreal than several of the others. "There are probably 
other plants in this group which further search would reveal. Of the 
sedges Carex Oederi, var. pumila is very common in wet pastures and 
by roadsides, both in clay and muck. Viola incognita is the common 
white violet of swamps and woods. Conioselinum is rare enough to 
please the botanist decidedly, when he discovers its bright green 
dissected leaves and white umbels of flowers. Heracleum is at only 
one station near the coast, but flourishes inland.
