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

 narrow-lanceolate. 



Ord. VI. GERANIACEiE. Juss. 



1. Geranium eriantkum; 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. 

 p. 641. 



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.
