On the side of shady hills, in rich vegetable mould,
among rocks: Canada to Virginia. . May. v. v.
Flowers white, with a yellow mouth. This singularly
constructed flower is known among the inhabitants by
the name of Breeches-flower or Yellow-breeches; and
as I consider that all those species with two spurs or
nectaries might form, with propriety, a good genus,
I have given it the name of Perizomanthus.

2. C. scapo nudo, racemo subcomposito nutante multifloro,

May-July. v. v. Flowers a lively bright red. This
elegant perennial deserves a place in every collection.
The Canada plant is somewhat different 16 aspect from
the Virginian, but not sufficiently distinct to make it a
species.
