Rydberg : Rocky Mountain flora 679 



3-4 mm. long, in fruit 8-10 mm. long, white-silky with long 

 spreading hairs ; corolla minute, shorter than thecalyx ; limb hardly 

 0.5 mm. wide; nutlets 3 mm. long, narrowly lanceolate, long-acu- 

 minate, strongly muricate ; groove closed, 2-forked at the base. 



The type sheet of this species was determined by Dr. Watson 

 as Eritrichiiim barbigeriDii. It is abundantly distinct from Cryp- 

 tautJie barbigcra, however, the main distinctions being the narrow 

 strigose leaves, the strigose instead of hirsute or hispid stem, the 

 minute corollas, and the narrower and differently shaped nutlets.

Cryptanthe confusa sp. no v. 



CryptiDitlie affiiiis Rydb. Mem. N. Y. Bot. Gard. I : 330, in 

 part. 1 900. 



Annual ; stem rather stout, hispid, branched ; leaves oblong or 

 oblong-oblanceolate, 2-5 cm. long, 3-8 mm. wide, coarsely hirsute ; 

 spikes at first very short, subcapitate, in age 4-5 cm. long ; calyx- 

 lobes 2 mm. long, lance-subulate, hispid, in fruit 3-4 mm. long; 

 corolla about 3 mm. long ; limb scarcely i mm. wide ; nutlets 

 ovate, 2 mm. long, light-colored, smooth, shining, thin-walled, 

 attached by the lower half or two thirds ; groove closed and simple 

 to the base. 



This species is related to CryptantJic affiiiis and C. leiocarpa, 

 but differs from both in the broader leaves. The nutlets are most 

 like those of the former but the attachment extends somewhat 

 higher.
