Maruhantiales — (ctinchuled). 



(^Continued from page .I'lO of V>,/. XXI 1.) 



Flmhriaria reticulata, n. s. Ditecious. Thallus yellowish lin'Oii, thin, 

 nnbrancheil, npto 6 mm. long and 4 mm. broad, obovate with a tlec'i) notch 

 at the apex. Margins entire. Dorsal snrface l!at. Stomata not prominent, 

 each bounded by one ring of t)-7 cells ; air chambers empty in two layers. 

 Ventral surface greenish ; scales purple ovate, appendage ovate entire. 

 Midrib broad, elliptic — oblong in transverse section, slightly projecting 

 ventrally, rather suddenly passing into the wings. Carpocephalum — stalk 

 naked reddish at base upto 4A^ mm. long ; receptacle Hat, stomata only 

 slightly raised spor<\gonia upto 4; pseudo-perianth hyaline, S exserted. 

 Spores, elaters and antheridia not seen. The apical part of the thallus in 

 sterile plants becomes narrowed and thickened, and persists in this con- 

 dition through the dry period. 



Habitat. — Kashmir, 8,000 ft. in a shady place along the road. 

 Fla(/iochasma ^imlensis, n. s. Dioecious or mon(Ccious. Thallus closely 

 creeping, bluish green, branched, upto lo mm. x4 mm. Margins entire or 

 slightly crenulate. Dorsal surface smooth, plane ; stometa not at all 

 prominent, very small, pore minute bounded by 4 or •"> cells ; upper epid- 

 ermis thin walled, trigones small. Ventral surface i)urple ; scales over- 

 lapping, triangular, entire, appendage not sharply constricted off from the 

 body, purple or hyaline. Transverse section of the thallus biconvex in the 

 middle gradually thinning towards the margins. Female receptacle sessile 

 or shortly stalked (stalk when present upto '1 mm.), concave dorsally. 

 Sporogonia 1 or '2. Spores broadly reticulate-lamellate ; margin spinulosc ; 

 about lli^ n. Elaters closely o-4-spiral, broad large, occasionally bran- 

 ched, 340-400 u. Male receptacles in a middorsal row, either on dilierent 

 lobes of the thallus bearing female receptacles or on difterent plants, 

 cushion like, circular or notched anteriorly. 



Habitat. — Simla, below Chota Simla, near a small stream, August. The 

 "aestivation " of the involucre is similar to that of other species described 

 by the writer before, (New Phyti>logist, Vol. XIII, No. i)), one valve being 

 iolded and the other being fullj^ opened out. 



Jungermannialex. 



liie/fa in(lira-<t., n. s. Plants submerged erect or ascending, Hrmly fixed to 

 the mud by rhizoids, often i:i dense patches, light green, simple or once or 

 twice forked, upto 10 mm. long. Often many branches are given ofi" from 

 the base and plants have a tufted habit. Wing well developed m early 

 stages upto 2 mm. broad ; in the fertile portion small and interrupted, 

 lateral leaves long and narrow, linear, conspicuous. Involucres upto on 

 each plant, densely situated, cylindrical pointed upto 2 mm. long, cells 

 papilliform. Spores reticulate spinous, 7-H reticulations in the diameter, 

 spines conspicuous projecting beyond the margins.
