Greene — Diagnoses Aragallorum. 13 



spike; flowers \ inch iDUg ; calyx with very short teeth broad at l)ase ; 

 villoiis-strigose coriaceous pods erect, sessile, Httle more than h incli long, 

 hardly twice the length of the calyx. 



Near Dallas, Texas, collected by Reverchon, and distributed by him and 

 also by A. 11. Curtiss, for .1. LdinhcrtI, from which it is abundantly distinct. 

 The spikes of flowers are commonly 2 inches long and nearly as broad. 

 Named in reference to the characteristically short calyx-teeth and short 

 pods. Type in my herbarium. 



Aragallus articulatus sp. nov. 



Erect, slender, 10 inches high, with pale glaucescent herbage sparingly 

 pilose; leaves 6 inches long, with 4 or 5 remote pairs of linear leaflets 

 about ■{ inch long, shorter than the iiiternodes of the rachis ujjou which 

 they are inserted by a distinct white callosity; flowei's unknown; pods 

 o inch long, sessile acute, strigulose. 



Collected on the Canadian River, perhaps within the limits of what is 

 now Colorado, by Dr. J. M. Bigelow, on Whipple's Expedition ; referred 

 by Dr. Torrey to A. Lrnnberit as a variety, as the label in his handwriting 

 in U. S. Herb, deniunstrates. It is doubtless the specimen (there are 

 two on the sheet) of which he speaks in Whipple's Report, p. 80, as having 

 " pods shorter and thicker, and strigose-hirsute." Both this and the other 

 " Oxijlropif; Laniherti" of Bigelow's collecting on the Canadian may be 

 supposed to have been included in Grays' var. Bigelovii. But the foliage 

 in A . articulatus is very peculiar, and the pods in A. Bigelovii are stipitate. 



Aragallus aboriginum sp. nov. 



Very stout, large-leaved but low, scarcely a foot high, whitish and glossy 

 with a dense longappressed pubescence ; leaves 7 or 8 inches long, of 7 to 9 

 pairs of li-inch-long leaflets all acute and inclining to lanceolate from 

 oblojig; stout scapes shorter than the leaves, bearing only a part of the long 

 spike above them ; short-cylindric calyx with triangular-subulate short 

 teeth; flowering spike 5 inches long, not dense; pods | inch long, hard- 

 cartilaginous, densely villous-tomentose. 



Cimarron Rivei-, Oklahoma, June, 1891, M. H. Carleton in U. S. Herb. 

 Very large and low white-flowered species. 



Aragallus falcatus sp. nov. 



Rather slendei-, a toot high ; mature herbage green, when very young 

 slightly glossy with a not dense appressed villous pubescence ; leaves 6 or 

 8 inches long, of 7 to 9 pairs of acutely lance-linear subfalcate firm leaflets 1 

 inch long or more; peduncles about equalling the leaves; spikes of red- 

 purple flowers about ."! inches long, not dense; bracts slender-subulate; 

 calyx subcampanulate, densely villous-tomentulose, the slender-subulate 

 teeth short ; densely tomentulose pod barely h inch long, erect, sessile, 

 little if at all exceeding the calyx-teeth. 



Watson, Missouri, June 1, 1894, B. F. Bush ; sent to U. S. Herb, for A. 

 Lamberti.
