On the side of shady hills, in rich vegetable mould,

 Flowers white, wiih 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.

 May — July. v. v. Flowers a lively bright red. This 

 elegant perennial deserves a place in every collection. 

 The Canada plant is somewhat different in aspect from 

 the Virginian, but not sufficiently distinct to make it a 

 species,
