short, 1-13 lines long, with small fine rootlets at base ; fructification on the 
upper side, seattered, mostly on nerve near the middle of the frond, some- 
times near the base, and sometimes at the forking but above it, and not 
unfrequently two on a frond; involucre broad, subplicate, deeply and finely 
laciniate, sometimes three occur on a branchlet ; calyptra cylindric, two 
lines long, whitish, glabrous, slightly rugulose, with delicate small fimbrie 
at the mouth; peduncle slender, 8-12 lines long; capsule linear, obtuse, 
1 line long, glossy dark brown, valves not cohering at tips ; spores circular, 
presenting a ringed appearance ; cellules very minute, chain-like, irregular 
in shape and size, mostly pentagonal. 
Hab, On clay banks, sides of streamlets near Norsewood, 1878-83 
(but barren): W.C.  Petane, near Napier, September, 1888: Mr. A. 
Hamilton ; profusely in fruit. 
Obs.—A species having alliance with S. subsimplea, Mitten, and S. pro- 
lifera, mihi (infra), but very distinct from both. Occasionally, however, a 
frond is met with slightly rooting from its centre, below the fruit-point, or 
from becoming recumbent, and sometimes, though rarely, by throwing out 
lateral fronds from its base. A few young fronds are also found intermixed, 
very narrow long and pointed ; these, I am inclined to believe, enlarge their 
pagina afterwards. 
3. S. melanoneuron, sp. no 
Plant small, single s bae. erect; frond reniform in outline, 7-8 
lines broad, 4—5 lines long, forked, once or twice divided, stoutish, wavy, 
colour dark olive, cellules small, oblong; segments few, sublinear-oblong, 
short, about 13 lines or more wide, not divided deeply, not decurrent on 
stipe, very slightly and distantly serrulated towards bases nct above, tips 
largely emarginate ; midrib stout, almost black, not extending to tips, in 
some segments midrib forked at tips; stipe 6-9 lines long, stoutish, black- 
brown; ¿involucre small, simply 2-8 times notched, on upper surface at 
second forkings above, 2-8 on a frond; antheridia on lower surface, under 
minute ovate leaf-like scales, scattered on both sides of the midrib. 
Hab.—On clay banks under ferns, &c., dark forests near Norsewood, 
1879-88: W.C.; and at Great Barrier Islet, 1888: Mr. C. P. Winkelmann. 
Obs.—This is another peculiar-looking species, of which I should have 
liked to have had better fruiting specimens. It is a rather scarce species 
and generally barren. I have long known it in this state, and I should not 
care now to describe it had I not been engaged lately in studying and 
working-up the several species I have described in this paper—besides my 
well-knowing all the other published N.Z. species of this genus. I have, 
therefore, no doubt of its being quite distinct as a species from all of them, 
although I find it hard to describe plainly in a few words its characteristic
