14 Greene Diagnoses Aragallorum. 



The next four species are of the northerly Rocky Mountain 

 regions, from western Dakota to Wyoming and Montana; all 

 but the fourth having passed with some for A. Lambert*. 



Aragallus formosus sp. nov. 



Stout, multicip.itous, the decumbent scapes 6 to 10 indies high ; herbage 

 neither silvery nor canescent, green, though far from glabrous, all the parts 

 clothed with a comparatively coarse appressed pilose pubescence ; leaflets 

 thinnish, 1} inches long, oblong-linear, very acute ; scapes little surpassing 

 the foliage ; spikes of large red flowers 1 o to 2% inches long, 1 in diameter ; 

 bracts lanceolate, hardly equalling the cylindric densely pilose calyx, this 

 with triangular-subulate acute teeth half as long as the tube; pods not 

 known. 



Black Hills near Fort Meade, South Dakota, June 7, 1887, Dr. W. H. For- 

 wood, U. S. A. ; specimens in U. S. Herb. Dr. Forwood describes the large 

 corollas as being cardinal red; and this is not improbable, though in the 

 dried state they are purple. 



Aragallus invenustus sp. nov. 



Multicipitous and decumbent, low, stoutish, villous-hirsute throughout; 

 leaflets very many, small and crowded, elliptic-oblong, | to inch long; 

 scapes 5 or 6 inches high, bearing the short spikes of whitish flowers a little 

 above the foliage ; bracts linear, much shorter than the calyx, this with 

 long cylindric tube and short, broadly subulate teeth; pods nearly an inch 

 long, ascending, the apiculation spreading, the whole villous-tomentose, 

 texture coriaceous. 



Known only from about Fort Meade, South Dakota, where it was collected, 

 in both flower and fruit, by Dr. \V. H. Forwood, in 1887; types in U.S. 

 Herb. 



Aragallus rigens sp. nov. 



Rigidly erect, 8 inches high, rather slender, pale-green but not silvery, 

 the pubescence scanty and strigulose ; leaves rather long-petioled and erect ; 

 the leaflets in about 5 or 6 pairs and remote, though longer than the inter- 

 nodes of the rachis, subcoriaceous, linear, acute, \ to 1 inch long, not cal 

 lous at base, yet inserted each in a conspicuous hollow of the rachis which is 

 thus notably articulated; flowers not seen ; pods hard-coriaceous, oblong, 

 abruptly beaked, the whole 4 inch long, strigulose ; calyx under the mature 

 pods campanulate and with very short triangular teeth. 



Cedar Creek, twelve miles above Glendive, Montana, July 15, 1884, L. F. 

 Ward, in U. S. Herb. In the emphasized articulation of its leaflets with 

 their rachis this must be regarded as a near ally of the geographically far 

 removed and otherwise distinct A. articalatus defined above.
