March, 1886 (3147). 



Plants small, bright glossy, yellowish-green; with julaceous 

 branches less than i cm. high ; stems red ; leaves small, i mm. 

 or less, imbricate, concave, those of the young branches obtuse 

 and closely imbricated, the vein dividing and ending below the 

 apex ; lower cells lax and enlarged, upper rhomboidal spindle- 

 shaped, forming small inconspicuous teeth. Dioecious. Pedicels 

 short, 5-7 mm. long, darker below ; capsules 2 mm. long, pen- 

 dant ; neck nearly half the length, contracted below the spore- 

 sac; lid mamillate, orange-colored, rim red; annulus large, falling 

 with the lid ; peristome double, outer of light yellow teeht, papil- 

 lose outside, trabeculate inside ; endostome a shorter membrane 

 with carinate segments, open along the keel, with rudiments of 

 two cilia between. 



Closely allied to Bryimi jiilacejnn Sm.,but differing from Euro- 

 pean specimens at Kew in the shorter more rigid branches, with 

 more closely imbricated leaves and shorter pedicels. Specimens 

 collected by Mandon near Guyaboya, 28th May, 1866, named 

 B.julaceiuiiy at Kew, differ in much longer, more slender branches 

 and pedicels 10-12 mm. long.

 Ingenio del Oro, lOOOO ft. (3148). 



Compared at Kew with specimens collected by Jameson from 

 Quito, nos. 1 51-200, and Pichincha, no. 328. Sent to Dr. Muller

 lanceolate carinate, serrate above the middle, margins bordered by 

 2-3 rows of elongated cells ; vein round, ending in a short mu- 

 cronate apex ; cells all regularly rhomboidal. Dioecious. Peri- 

 chetial shorter with a longer mucronate tip. Pedicels straight or 

 bent, about 2 cm. high, glossy yellow; capsules nodding, 4-5 mm.
