NORTHEASTERN ASIA. Transbaikalia to Kamtchatka. 



According to Rydberg (in Bull. N. York Bot. Gard. I. 260 [1899]), the true S. 

 reticulata is absent from North America, and S. vestita Pursh (Fl. Am. Sept. II. 

 610 [1814]) does not occur in Asia. The specimens mentioned by Herder, 1. c. 451, 

 as S. reticulata, var. sericea Andersson belong to S. reticulata Linnaeus and not to 

 S. vestita Pursh, which differs in its shorter-stalked leaves with a persistent silky 

 pubescence on the lower surface. The petioles are only about as long as the buds.

This section is apparently nearly related to sect. Herbaceae, but differs in the 

 leaves, which are paler below and have a different venation. The geographical 

 distribution of the species is also entirely different; the Himalaya and the high 

 mountains of western China being regions where no species of sect. Her- 

 baceae occurs.
