A rather rare native of bogs, from the Central and New 

 York States of N. America to Kentucky and Wisconsin, 

 extending thence into Canada to the northward, and to the 

 Platte Plains and Rocky Mountains to the westward. As a 

 species it is closely allied to the more common Ameri- 

 can yellow-flowered C. pubescens (Tab. Nost. 911, sub nom. 

 parvijlori) and C. parviflorum (Tab. Nost. 3024), from which 

 in a dried state it is with difficulty distinguishable, but from 

 both of which the colour of the flower separates it, whilst the 

 former has a much larger flower and more globose lip. Like 

 all the boreal Cypripedia, this is easily cultivated in a bog 

 soil, with a cool bottom, plenty of shade, and a copious litter- 

 ing of dead leaves. The specimen figured was from roots 

 communicated by Mr. J. Dunlop, of Milwaukie, U.S. 

 America, which flowered at Kew in May of the present 

 year. 



Descb. Whole plant more or less glandular-pubescent.
