A tall growing elegant species, found here exclusively in 

 our higher mountains and there rarely. It appears to be 

 more common to the north ; and often attains a height of 

 ten or more inches, with a proportionably slender stem j 

 below there are but few leaves. The flowers are remark- 

 able for the shortness of the horn or nectary and the long 

 attenuated narrow petals. These are purple outside and 

 whitish within, finely striated. Willdenow's description is 

 a very good one. It flowers late in May and beginning of 

 June. Northwardly it seems by the New- York catalogue 

 to flower still later, in July. It is difficult to express the 

 manner in which the leaves are almost rectangularly bent 

 down — but it is a striking habit to the observer.

The striata of Elliott I think must belong to my debilis, 

 as does the striata of Muhl. Cat. by specimens. 



I have very particularly studied this and the two follow- 

 ing species — and kel satisfied that they are specifically very 

 distinct.
