The leaves of C. Fischerianum, from the same country, are described as ovate ; those of our plant are 

 narrow-lanceolate.

1. Geranium erianthum; caule tereti subsimplici inferne nudo, foliis omnibus petiolatis 

 palmato-5-7-lobis lobis incisis acute serratis laceris, pedunculis confertis abbreviatis, 

 calycibus villosissimis, petalis integris, staminum filamentis pilosis. De Cand. Prodr. v. 1 .

The G. eriostemon, of Fischer and De Candolle, does not appear to us to be distinct from this.

This plant (the var. /3.) is probably distinct from the P. villosa, which Chamisso remarks is not found 

 on the Asiatic side of Behring's Strait. Ours is much slenderer and more procumbent: the leaves are 

 thinner, with the nerves not impressed; on both sides, especially at the margins, they are sericeo-pilose 

 with appressed hairs, not at all white, nor with prominent veins beneath.
