16 PROCEEDINGS OF THE ACADEMY OF [1898. 



one mentioned by Pursh as having been collected by Lewis and Clark 

 was his C. hirsidissima, there is every reason to believe that this is 

 the real type (or portion of type) of C. hirsidissima Pnrsh. But 

 the specimen is certainly C. Douglasii Hook., a later species, and 

 not Anemone patens, as it has been traditionally interpreted. On 

 reading the description of C. hirsidissima in Pursh's Flora it is 

 impossible to doubt that it refers to C. Douglasii with its 4 sepals, 

 not Anemone patens with its 5 to 8 sepals. This fact was, I think, 

 guessed by Mr. Coville, some years ago, but I fail to find any pub- 

 lication of it. Certainly Prof. Britton in his Flora does not challenge 

 the identity of Anemone patens, var. Nuttalliana with Clematis hir- 

 sidissima, for he still keeps up his Anemone hirsidissima (Pursh) 

 Britton. 



It seems only right that C. Douglasii Hook, should give place to 

 the older and well described (although long misunderstood) C. hir- 

 sidissima Pursh. This is certainly an interesting point. Perhaps 

 before publishing it, it might be courteous to Mr. Coville to inquire 

 whether he had already published or had in press anything on the 

 subject, which is unlikely. Some reference also might be made 

 to the fact that he had independently and without a knowledge of 

 Lewis's type discovered from the description the probable identity 

 of C. hirsutissima, Pursh. 



In the list, Anemone quinquefolia is used to mean all N. American 

 "A. nemorosa," not in the sense in which Pursh understood it, 

 namely as covering only the quinquefoliolate form. 



The type of Cleome serrulata Pursh (at least one of the specimens) 

 shows slight serrulation of the leaves, so that the name ought not to 

 give place to the later C. integrifolia Torr. & Gray, although the 

 latter is, in general, more appropriate, or would be if the authors had 

 only written integrifoliolata. 



The specimen of Lewisia triphylla (Claytonia triphylla Wats.) ex- 

 tends the known range of the species to Idaho. 



Pursh's Oxytropis argentata is evidently larger than 0. nana Nutt. 

 to which it has traditionally been referred, and also has longer, more 

 slender calyx lobes. Perhaps these are only varietal differences. 

 Their value can be told only by some one with a monographic 

 knowledge of the genus. 



Strangely enough Pursh's Pedicularis elata looks exceedingly like 

 P. scopulorum Gray from a very different range. It is certainly 

 not P. bracteosa Benth. to which it is traditionally referred.
