The leaves are ovate to rhombic-orbicular, more or less abruptly cuneate, tapering into 

 an elongated margined petiole, toothed, crenate, or nearly entire; scape two or three times 

 the length of the leaf; bracts lanceolate-subulate, somewhat gibbose at base, and three 

 to six times shorter than the glabrous pedicels; umbel few- to several-flowered, generally 

 6-7-flowered; calyx campanulate and parted to the middle; teeth obtuse or subacute; 

 and the tube of the corolla about one and one-half times the length of the calyx. Ac- 

 cording to Fianchet the capsule is twice the length of the calyx. 



Our plants coincide exactly with the descriptions of P. Faurice, Franch., and I have 

 no doubt of their being identical, though my specimens have no fully ripened capsules for 

 comparison. From the continental var. armena, our plant differs in the rounded blades 

 of the leaves and longer pedicels. Whether the capsule of the former is also as long as 

 ours or not I have no means of determining at present either from the specimens or from 

 the descriptions. The size of the capsule in P.farinosa seems to be quite variable. In 

 some of the European, and especially in the American plants, the capsule often attains the 

 size of about twice the length of the calyx. Pax wrongly included P. Faurice and also 

 P. macrocarpa, Max., under his new sect. Macrocarpai. These plants properly belong 

 to his sect. Farinosce. Their flowers are not so large as those of P. cuneifolia, and their 

 bracts are somewhat gibbose. The younger leaves in the specimens of P. macrocarpa 

 in the Gray Herbarium show distinctly the yellow poAvdcr on their under surface, though 

 the older leaves and calyx are completely naked. The plant is hardly distinguishable 

 from the American P. mistassinica, Michx. (P.farinosa, var. mistassinica, Pax), either 

 the shape and size of the flowers and capsules, or by the character of the leaves and their 

 teeth. 



The species is very variable and widely distributed in the arctic and cool temperate 

 regions of Europe, northern Asia and North America, and also in antarctic America.
