The Kurile plant coincides exactly with the Fuji specimen collected by Tschonoski, ex- 

 cept in size. It is about two to three feet high, and the leaves are more distantly placed. 

 P. tripterocarpum, A. Gray, in MS. [Ochotsk Sea (J. Small) ; Arakamtschetchene Isl- 

 and, Bering Straits (Wright) ; Plover Bay, eastern Siberia (Dall)], approaches our plant 

 nearest in the characters of its flowers and fruit. The leaves are linear-lanceolate, short- 

 petioled or subsessile, usually crowded two or three together at the nodes, smooth or 

 sometimes slightly hairy on the veins beneath, ciliate and somewhat revolute at the mar- 

 gins; sheath entire; pilose, especially at the base. (See Rothrock, Fl. Alaska, p. 453.)
