It is a native of the North-west of America, and Kamt- 

 chatka ; and from specimens collected there it was originally 

 described by DeCandolle, who placed it near the Dahurian 

 G. eriostemon, a very distinct plant with long stiff white 

 hairs all over the lower part of the filaments, and the base 

 of the petals furred at the margin. 



But Drs. Torrey and Gray, in their Flora of North 

 America, in the first place combined, with a quaere, the two 

 species last mentioned, and assigned to G. erianthum a furred 

 margin to the petals, which is the character of G. eriostemon 

 and not of G. erianthum ; so that it is probable that their 

 G. erianthum is really G. eriostemon. In the next place 

 these authors also refer with doubt to their G. erianthum, 

 a plant gathered by Douglas in North-west America, which 

 Sir W. Hooker regarded as a downy variety of G. macula- 

 tum. That plant, which is now before me, is however neither 

 the one nor the other ; it has the furred margin of the petals 

 characteristic of G. eriostemon, but it wants the long stiff 

 hairs on the stamens of that plant, and it has a different habit ; 

 aoreeinof with it however in the hairs which clothe its stem 

 being reflexed. 



Upon looking into Steudel I find that compiler referring 

 G. albiflorum of Hooker to G. erianthum, although the former 

 is quite another species, with smooth calyxes ; but he states 

 that G. albiflorum of Hooker is not the same as the plant so 

 named by Ledebour. I find, however, that Drs. Torrey and 

 Gray (vol. 1. p. 678) regard those two as the same species, 

 and w^ould cancel the name G. Richardsonii given by Fischer 

 and Meyer to the North-west American plant. Upon this 

 point I will only observe that in G. albiflorum the leaves 

 are usually divided in a shallow way into five lobes, that the 

 calyx is quite smooth, the petals no longer than the sepals, 

 and hairv^ at the edges only, or very slightly on the surface ; 

 while in G. Richardsonii the leaves are mostly cut into three 

 deep partitions, the calyx is glandular, and the petals much 

 longer than the sepals, with their edge and surface equally 

 hairy.
