250 K. MIYABE ON THE 



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

 anelong-atedmarg-inedpetiole, toothed, crenate, or nearly entire; scape two or three times 

 the length of the leaf; bracts lanceolate-subulate, somewhiit gibljose at base, and three 

 to six times shortei' th;in the glal)rous pedicels; umbel few- to several-flowered, generally 

 G-7-llovvered; 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 calj'x. Ac- 

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



Our plants coincide exactly with the descriptions of P. Faur!(K, Franch., and I have 

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

 comparison. From the continental var. annena, owr plant differs in the I'ounded 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.farlnosa 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. Faurke and also 

 P. macrocarpa, Max., under liis new sect. Jiacrocarjpcp. These plants properly belong 

 to his sect. Farinosa'. Their flowers are not so large as those of P. ciineifolla, and their 

 bi'acts are somewhat gibbose. The younger leaves in the specimens of P. macrocarpa 

 in the Gray Hei'bai'ium show distinctly the yellow powder on their under siu'face, though 

 the oldei' leaves and calyx are completely naked. The plant is hardly distingnishable 

 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.
