 and the present.

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

 among rocks : Canada to Virginia. 1/ . 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, 

 , X have given it the name of Perizomanthits . 



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



nectariis brevissimis incurvis, stylo porrecto, laciniis 

 foliorum oblongis inciso-pinnatifidis, radice tuberosa.

 Carolina mountains, in the clitfs of shady rocks. 1/ .

 elegant perennial deserves a place in every collection. 

 The Canada plant is somewhat ditFerent in aspect from 

 the Virginian, but not sufficiently distinct to make it a 

 species.
