POLYTRICHADELPHUS INTEGRIFOLIUS CM., n. Sp. Unduavi, lOOOO 



ft. October, 1885 (3159a). 



Stems 5-8 cm. high, leafless below and tomentose, proliferous 

 at apex; leaves erect, slightly spreading, vein broad, excurrent 

 into a smooth, dark awn; margins entire, incurved; lamellae 

 seven, rows of cells high, uppermost cells rounded in section. 

 Dioecious. Perigonial bracts scarious, with short triangular 

 points. 



Male plants only collected, and from the robust stems and 

 broad, scarious, perigonial bracts it strongly resembles Polytri- 

 chum. Compared with various species of PolytricliadclpJuis at 

 Kew, none of which it resembles.

 ■ Polytriclnun aristifioriim Mitt. Unduavi, 8000 ft. October 



1885 (3155a). 



This species has also been collected at Yungas by Pearce 

 There are a great many diverse localities cited for this species by 

 Mitten, and there is as much diversity in the specimens at Kew. 

 We referred all of Dr. Rusby's specimens from Yungas, nos. 3155b 

 and c and no. 3155a from Sorata and 3155c from Mapiri to this 

 species, but Dr. Miiller gave it a manuscript name, which is ante- 

 dated by P. patnliim Harvey (Miill. Syn. Muse, i : 210) from Ne- 

 paul. It seems probable that there is room for the separation of 

 several species, but as ours agree with Jameson's from the Andes
