Resembling B. andina Mitt, in its secund leaves, but when 

 compared with Spruce no. 429 from Pichincha they are quite dis- 

 tinct, our species belonging to the section with B. araiaia and B. 

 scopa) ia ,h\.\\. agreeing with neither. The absence of fruit prevents 

 the determination of its closest alliance.

31:161. 1892. Sorata 1 3000 ft. February, 1886 (3137). 



Large plants of a glossy golden green color ; stems 6-7 cm. 

 high densely matted with brown tomentum below ; capsules few 

 and immature. 



Mixed with and resembling B. tomciitosa, but differing in its 

 squarrose, not secund leaves, which are longer and more sharply 

 acuminate, and serrate.

Plants decumbent and matted together with brown tomentum 

 at base; stems 3-4 cm. high ; leaves very brittle, with a conspicu- 

 ous, white, clasping imbricate base, those of the young branches 

 with a slender twisted apex 3-5 mm. long ; older ones all broken 

 off, the white base smooth, the upper part opaque and papillose 

 on the short walls of the cells ; margins bordered by i row of 

 long yellow cells with small appressed teeth ; vein narrow, toothed 

 on back. Dioecious. Perichetial leaves with a short base and 

 long serrate awn. Pedicel curved, 5 mm. long, red; capsule 

 curved, 2 mm. long, with a small orange-colored lid ; mouth 

 small ; walls ribbed ; peristome short, double. 



Allied to B. potosica Mont., but differing in the longer, less 

 crowded, more spreading leaves with a more conspicuous white 

 clasping base. Named by Dr. Miiller for Dr. Rusby but Schim- 

 per's name has priority.
