■3. H. atrovircns, sp. nov. 



Plant terrestrial, loosely tufted, sub-erect, l^m. high. 

 Stem simple (rarely branched), dark-coloured (young stems 

 reddish-brown, glossy), stout, leafy, with many dark-brown 

 rootlets at base. Leaves quadrifariously disposed, free, loosely 

 imbricated at top, dark olive-green (young leaves green) ; mar- 

 gins entire, but under a powerful lens slightly and irregularly 

 denticulate near tip, though not serrated ; cells large, hexa- 

 gonal-orbicular, but hexagonal-oblong at base, their centres 

 blotched with irregular dark dots, very small at margins : 

 lateral leaves spreading, 2 lines long, elliptic or elliptic-ovate, 

 tip obtuse ; nerve very stout, colour of leaf, extending two- 

 thirds length of leaf, and slightly bifid near top : dorsal and 

 ventral sub-orbicular, a little shorter than lateral. Peri- 

 chaetial small, numerous, orbicular, apiculate, apex blunt and 

 excised on each side, serrulate ; cells smaller ; nerve 0. 

 Fruit-stalk very stout, -^ in. -fin. long, black, shining, curved, 

 4-6 on a branch, thick and bulbous at base. Capsule (old) 

 small, 1 line long, oval, slightly tubercled at base, dark-brown, 

 nodding. Calyptra (young) linear, sub-acute, li lines long, 

 black, smooth, grey and slightly jagged at base. i\ntheridia,

Obs. This plant shrivels much and becomes black in dry- 

 ing. Its nearest affinity seems to be with II. quadrifaria, Sm., 

 and II. robusta, Hook. f. 



4. H. flava, sp. nov. 



Plant small, |^in.— lin. long, leafy to base, stems branched 

 above, main stem and branches dark-red. Leaves yellowish- 

 green, sub-quadrifariously disposed, thickly set, imbricate, 

 ^Jine long, obovate-spathulate, apiculate, tapering to base, 

 margined, entire, slightly uneven, very crisp when dry; nerve 

 strong, single, fiexuous, extending through four-fifths of leaf. 

 Pericliaitial few, erect, sub-linear-oblong, apiculate. Cells 

 compact, orbicular, very minute at tips, larger at centre and 

 increasing in size to base, where they are very clear parallelo- 

 grammatic and oblong-hexagonal. Fruit-stalk (immature) 

 short. Calyptra smooth, beak very long.
