from the back part of the superior petal is a little curved and 

 tinged with blue at the point. Anthers five, compressed, 

 cohering, membranaceous at the apex. Style short. Stigma 

 green, globular, with an opening at the top, bea ded at 

 the lower part. The whole plant is quite smooth. The 

 shortness of the stem and the strong peduncles, springing up 

 so near to the root, upon a superficial view, give the ap- 

 pearance of its belonging to the first division, the acaules ; 

 but it really belongs to the third, or such as have pinnatifid 

 stipules and a hollow stigma. 



There are several specimens of this plant in Pallas's 

 Herbarium, now in the possession of Mr. Lambert, which 

 have the name of altaica attached to them in the Professor's 

 own writing. 



It has usually been called unijlora, a species with which 

 it scarcely agrees in any one character ; but the circumstance 

 of the flowers coming out so near the root, and more usually 

 only one at a time, has probably occasioned it to be so called 

 by persons, who, little conversant with botanical characterSj 

 are satisfied with any name that seems at all applicable. 



Native of Siberia, on the Altaic mountains. A hardy 

 perennial. Propagated by seeds, which it produces freely, 

 or by parting the roots. Communicated by Mr. Knight, of 

 the Exotic Nursery, King's-Road.
