W. H. PEARSON: HEPATIC. 25 
lata, cellulis 2 interioribus minutissimis costam obtegentibus et 2 lateralibus 
(intramarginalibus) quadratis vel oblongo-quadratis. 
Inflorescentia feminea ramulo postico brevi orta; bracteæ e cellulis teneris 
oblongis composite lanceolateeacuminatee. Perianthia et androecia haud visa. 
Dimensions. Stems + inch long, 5 mm. wide, :2 mm. thick; costa ‘05 mm. 
wide ; middle antical cells 15 mm. x 1 mm., marginal cells 1 mm. ; setze 
'075 mm. long ; bracts ‘4 mm. long. ` 
Obs. Differs from Z. setulosa Leitgeb in being more robust and rigid ; in 
the marginal cells having a narrow sinus between two of them, not a large 
gap; setæ usually longer and narrower ; perichætial bracts small and very 
delicate, composed of narrow elongate delicate cells, quite different from the 
stem cells ; in Z. setulosa the cells of the bracts are large, similar to the cells 
of the stem. 
Hab. Ignambi. On gneiss rocks, in moist air, 3000 ft. 1531. 
NOWELLIA BORNEENSIS (De Not.), Schiffner. 
Dioieous. Minute, 3 to 4 cells wide, pale yellow in colour; creeping 
amongst other hepaties. Stem simple or with few postical branches, radi- 
culose, rhizoids single, long, hyaline, with suckers. Leaves distant, alternate, 
often secund, semi-amplexicaul, erect, usually parallel with the stem, bifid to 
the middle or below, segments setaceous, 4 to 8 uniseriate cells long, 2 cells 
wide at the base, hamato-incurved or spreading, proceeding from the angles 
of the lobe, lobe 4 cells wide at the mouth, cucullate, inflated, keel smooth, 
arcuate; cells small, quadrate, walls thin, no trigones. No underleaves. 
Inflorescence $ on short postical branches; bracts broadly lanceolate, bifid 
to about the middle, segments acuminate, serrate. Andreecia on short 
postical branches, 3 to 4 pairs of perigonial bracts, closely imbricate, oval, 
lobe acute, lobule similar, almost equal in size ; antheridia oval. 
Dimensions. Stems 4 to Zinch long; diam. of stem ‘05 mm. ; with leaves 
-3 mm. wide ; leaves, lobe *15 mm. x 1 mm., ‘15 mm. x'15 mm., sete *1 mm. 
to 2 mm. long; cells ‘02 mm. ; perigonial bracts ‘2 mm.x 125 mm. ; anthe- 
ridia ‘075 mm. x ‘05 mm. 
Obs. One of the smallest and most beautiful of hepatics; De Notaris’s 
figures are fairly good and enable the species to be recognized. 
Nowellia eurvifolia (Hook.) from Japan, of which I have seen specimens 
(Mt. Yokagura, Tosa; coll. Shutai Okamura), agrees in every particular 
with our native species. 
Hab. Mont Koghi. On upper surface of fallen log. Forest, 3000 ft. 
740.
