terminal, nodding, white, at the base externally green, and 

 within at the base, sprinkled with small purplish spots. 

 Petals tipped with a green, callous, slightly pubescent 

 apex, the three outer ones ovate, the three inner ones obo- 

 vate and broader, all gibbous on the outside near the base, 

 and there, on the inside, each having a round, green, con- 

 spicuous pit, containing honey. Stamens included ; fila- 

 ments straight, white, collected together in the centre of 

 the flower; Anthers yellow, linear, erect, very loosely 

 attached. Pistil longer than the stamens ; stigma trifid, 

 slightly diverging ; style straight, somewhat clavate, three- 

 sided, twice the length of the anthers, colourless ; Germen 

 green, with six prominent, brownish, somewhat waved, lon- 

 gitudinal angles. Ovules numerous, in two rows within 

 the three cells of the capsule, ovate, flattened, attached by 

 their apices to the central receptacle. 



This species, which I conceive should follow P. pyre- 

 naica in the arrangement of the Genus, is a native of the 

 Altaic Mountains, and was obligingly communicated in 

 September, 1830, from the Botanic Garden of Edinburgh, 

 where it flowered in the open border in the beginning of 

 May.
