uous white hairs, ovate and quite concave in the middle with a

 gins double or recurved, bluntly papillose, frequently brown 

 in the upper half with elongated cells in the centre of the base, and 

 others sinuous; apex serrulate or erose when long and hyaline; 

 perichetium short, 3 mm., enclosing very long paraphyses, bracts 

 strongly plicate, cells long and clear, apex not hyaline ; pedicels 

 I cm. long, capsules about 3 mm. with small orange-colored

Mandon's specimens at Kew in Herb. Schimper are somewhat 

 larger and lighter colored than Dr. Rusby's, but agree in all es- 

 sential characters, especially no. 1641 of the Exsiccatae in Herb. 

 Hooker. Sent to Dr. MuUer as H. cUrhifolia (Wils.) Mitt. (J. L. 

 Soc. xii., 406, ex descriptio) and named by him Braunia argyrocarpa 

 n, sp., also to Bescherelle, who says," ut videtur foliis tamen apice 

 diaphanis quod nos indicat Mitten." 

 Braunia subplicata E. G. Britton, n. sp. Ingenio del Oro, loooo 



ft, May, 1886 (3154); Mapiri, 5000 ft. (3154a). 



Plants dark brownish green, in large dense mats, stems de- 

 cumbent, pinnately branched, often giving off radiculose stolons, 

 branches erect, 4-5 cm. long ; leaves subsecund when moist, im- 

 bricate and erect when dry, with three blunt ridges, not hyaline 

 pointed, ovate-concave, over i mm. long, less than i mm. broad, 

 with entire revolute margins and a conspicuously rolled border to 

 the concave center, apex acute and concave, erose dentate, but not 

 hyaline, conspicuously papillose at the tips of the branches, basal 

 cells elongated brown, others regular and sinuous; perichetium 

 narrowly lanceolate, erect, sulcate, 3 mm. long, with oblong yellow 

 cells at base and middle and blunt erose tips ; pedicels i cm. long, 

 erect or cernuous twisted, fulvous as well as the base of the cap- 

 sule, which is 2 mm. long with a straight beak over i mm. long, 

 mouth with a thick red rim, calyptra brown, 3 mm. long, tufted 

 and ragged at base with a straight beak i mm. long. 



Differs from H. plicata Mitt. (Bridget, Bolivia in Herb. Hooker) 

 in the dull brown color of the plants and in the leaves not being hy- 

 aline tipped ; from H. secnnda (Hook. Musci Exot. t. 46, Humboldt's 

 type in Herb. Hooker) in the larger, less secund leaves with more 

 strongly revolute margins ; resembling only an unnamed scrap in 

 Herb. Hooker, collected by Mathews in Peru at Casapi, and a 

 part of Braunia siibsecunda Sch. M. S., no. 5, in Herb. Schimper 

 without locality or name of collecter. (See Jaeger, p. 86) pencilled 

 Mexico? by J. G. Baker. Sent to E. Bescherelle as B. plicata 

 Mitt, he says = •' ? var, foliis inajoribus !"
