Aragallus angustatus sp. no v. 



Acaulescent perennial ; leaves spreading or ascending, 6-10 

 cm. long; leaflets 7—13, narrowly linear-lanceolate to narrowly 

 linear, 1-2 cm. long, 2—4 mm. wide, sparingly strigose ; scape 

 about I dm. high, sparingl}^ strigose ; raceme 3—5 cm. long ; 

 bracts lanceolate, about 5 mm. long; calyx finely silky-strigose ; 

 tube 5-6 mm. long ; teeth subulate, about 2 mm. long ; corolla 

 purple, I 5 mm. long or less ; banner rather broad ; wings broad 

 and slightly emarginate ; keel with a very dark blue-purple spot 

 and a very short porrect tip; legume ovoid, less than 1.5 cm. 

 long, coriaceous, 3.5 mm. thick, rather abruptly contracted into a 

 spreading beak, minutely strigose, half 2-celled. 



This resembles, somewhat, a low, narrow-leaved A. Lambertii, 

 but differs in the more spreading leaves, and smaller, more 

 spreading flowers, and especially by the short pod, with an abrupt 

 spreading beak. The specimen designated as the type has the best 

 developed fruit.

Aragallus Blankinshipii A. Nelson 



Prof J. W. Blankinship * writes : 



" Oxytropis Besseyi (R}'dberg) ; Aragallus Besseyi Rydberg, 

 Flora 250 is A. Blankinshipii Nelson, Erythea, 7: 58. The 

 types of both were collected within a few miles of each other. 

 The fruiting specimens of Nelson were pathogenic, infected with 

 uredo, causing the ovary to remain undeveloped and an abnormal 

 calyx, the legume in the species usually exceeding the calyx ; 

 otherwise they are identical." 



This statement is only partly correct. Professor Blankinship 

 some time ago sent us specimens of Aragallus Blankinshipii from 



* Mont. Agr. College Sci. Slud. Bot. i : 80. 1905.
