Greene Diagnoses Aragallorum. 15 



Aragallus ventosus sp. nov. 



Low and mill tici pi tons, canescently silky-villous ; leaves long-petioled 

 and slender, the 3 pairs of oblong-elliptical leaflets approximate at the end of 

 the petiole, so to speak, about k inch long; slender peduncles twice the 

 height of the leaves and about 5 or 6 inches long including the short capiti- 

 fonn spike; bracts lance-linear, villous-strigose, as are also the calyx-tube 

 and its rather long linear teeth ; keel of corolla with a short straight blunt 

 point; pod unknown. 



Dry ground in the valley of the North Fork of Wind River, Wyoming 

 July 12, 1882, Dr. W. H. Forwood ; type in U. S. Herb., labelled Oxytropis 

 L'if/opus, and doubtless related thereto, though a plant of slender habit, of 

 few long leaflets as it were at the end only of a long petiole; also wholly 

 destitute of the woolly-hairiness of A. lagopns. 



Northward beyond the borders of the United States occur 

 several more species proposed as new ; several of these so mani 

 festly allied to A. Lamberti as to have been labelled so in the 

 herbaria. These have all been collected by the efficient and 

 zealous botanists of the Canadian Geological Survey, and as 

 distributed bear the numbers of that collection. 



Aragallus Albertinus sp. nov. 



Rather slender, 6 to 12 inches high, silvery-silky only as to the young 

 and growing parts, when maturer glabrate, the green-looking upper face 

 of leaflets only sparsely villous-pilose under a lens, these in numerous closely 

 approximated pairs, hardly f inch long, oblong-lanceolate, very acute; 

 spikes of whitish or purplish flowers narrow and dense, borne well above 

 the foliage; bracts subulate-linear, nearly equalling the calyx, this villous- 

 tomentose and white, the subulate teeth almost as long as the subcampanu- 

 latetube; pods short, conspicuously acuminate, the beak-like point spread 

 ing, and only this surpassing the calyx-teeth. 



A rather elegant and certainly well marked species, of which the type 

 is from near Prince Albert, Saskatchewan, by Mr. John Macoun, July, 1896, 

 sent me under the Geol. Survey No. 12,540; also in flower only, under No. 

 12,535. Earlier specimens referred here are from two localities in Alberta 

 taken in 1895. Types in my herbarium. 



Aragallus melanodontus sp. nov. 



Stout, low, multicipitous, the erect scapes 5 inches high ; plant villous- 

 canescent, the hairs partly appressed, partly spreading; leaflets in 5 to 7 

 pairs, oval to oblong-lanceolate, acute, } to | inch long ; flowers large, white, 

 in spikes little longer than broad; bracts subulate, not half as long as the 

 rather large short-cylindric calyx, this villous with short dark-colored and
