 mens collected are narrowly ovate, up to 1.5 cm. long, and 0,7 cm. broad, gradually 

 and slightly acuminate towards the summit, 1'. ohlonffifolid, Fenzl, 1. c; Regel, 1. c.

This species is especially characteristic in having the stems rigid, erect and distinctly 

 quadrangular; the leaves are sessile, rather broad and lanceolate, frequently of a paler 

 greyish colour on the under side, and with a strongly marked midrib and recurved 

 margin. Not unfrequenl in meadows on the islets in the lower part of the river Abakan, and 

 in the Yenisei, where I have collected it with flowers at the end of June. The speci- 

 mens agree perfectly with sj)ccimens I have seen in K.\no, Plantae Amuricae el Zeaense, 

 no. 143.
