* Aragallus foliolosus (Hook.); Oxyfropis foliolosa Hook. Fl. Bor. 



Am. I : 146. 



This has been regarded as a depauperate alpine form of A. de- 

 Jlexiis. It differs, however, not only being stemless, but in the 

 capitate spike, the bracts little more than half the length of the 

 calyx, the pubescence finer and more appressed, and the shorter pod 

 only about i cm. long, black-hairy, and scarcely deflexed in fruit. 

 It is very nearly related to A. I^aj>ponicus (^Oxytropis Lapfonicd) of 

 Europe. 



Within the region it grows at an altitude of over 3000 m.
