Hab. About Carlton-House on the Saskatchawan. Vrutmnond, — Very few specimens of this plant are 

 in the Herbarium, and those have the fruit immature. In that state, I find no dissepiment within the 

 legume, and am inclined to think it would be more correctly placed with the PhaceVy and very near to P, 

 villosa, {Astragalus villosusj Mich.) The size of the two plants is nearly alike, and their general 

 appearance; but in P. villosa, (which I possess from Mr. Nuttall,) the leaflets are broader, fjir more decidedly 

 villous, the flowers more numerous in each head, but of similar colour and structure, and the legiimes 

 appear to be the same in both.

Hab. First, I believe, gathered by Mr. Wright, very many years ago, in Hudson's Bay. {Herb, mstr.) 

 Eagle and Red-Deer Hills of the Saskatchawan. Douglas. Carlton-House. Dr. Rickardson.~^The present 

 very fine species, which Mr. Douglas wishes should bear the name of the indefatigable Druramond, has been 

 long known to me from a specimen gathered more than thirty years ago, by Mr. Wright, son of the late 

 eminent Dr. Wright of Edinburgh, in Hudson^s Bay, but which, from its habit, (and being destitute of 

 fruit,) I was led to refer to the genus Phaca. Its nearest affinity seems to be with the A. galegoidcs, Nutt., 

 (A. racemosus, Pursh and De Cand.) : but that, besides being an inhabitant of more southern latitudes, is 

 described as only subpubescent, whereas our plant is so remarkable for its hairiness, that Mr. Douglas 

 in his MSS. has aptly compared it to the Oxytropis pilosa of the Old Worid.*

• There is another species of Astragalus described in Mr. Douglas* MSS. under the came of-" A. miter: caules- 

 cens debilis, stipulis acumiuatis, foliolis lineaiibus r>-6-jugia subpubescentibus, calycibus nigricantibus.— On low hills 

 of Spokan River, sixty mUes from its confluence with the Columbia. Fl. May, June, If." But of this I have seen 



no specimen.
