1020 FILICES. [Gleichema. 
Allied to G. flabellata, but the fronds spread in a horizontal plane, and are 
much more rigid and coriaceous, and the segments are shorter and narrower, 
quite entire, and glaucous beneath. It appears to be confined to New Zea- 
Jand. 
4. G. flabellata, #. Br. Prodr. 161.—From 1 to 4 ft. high. Bhi- 
zome long, stout, branched, more or less clothed with reddish- 
brown laciniate scales. Stipes erect, cylindrical below, subcom- 
pressed above, slightlv scaly or almost glabrous. Fronds several times 
dichotomously branched, ascending and fan-shaped, not spreading 
in a horizontal plane, often proliferous from the lower forks, so that 
there are sometimes 2-3 tiers of superposed branches. Ultimate 
branches or pinne 4-12in. long, 1-2in. broad, lanceolate, acumi- 
nate or caudate, deeply pectinate-pinnatifid or pinnate towards the 
base. Segments close-set, ascending, 4—-lin. long, narrow-lmear, 
subacute, serrulate towards the tip, dilated at the base, green on 
both surfaces, glabrous above, often more or less scaly-pubescent 
beneath. Transverse veins numerous, forked near the base. Sori 
copious, solitary on one of the veinlets, of 3-5 sporangia.—A. Cunn.

Norru Istanp: Auckland— Not uncommon by the side of streams, &c., 
from the North Cape to the Bay of Islands, rare and local southwards to the 
Kauaeranga River (Thames) and the Manukau Harbour. 
Also in Australia, ranging from Queensland to Tasmania, and in New 
‘Caledonia. Mr. Colenso’s G. littoralisis certainly nothing more than a dwarf 
state, usually occurring near the sea. 
5. G. dichotoma, Hook. f. Sp. Fil. i. 12.—Usually from 2 to 4 ft. 
high, but sometimes dwarfed to a few inches, and occasion- 
ally reaching 6ft. Rhizome long, slender, clothed with narrow 
reddish-brown bristly scales Stipes slender, smooth and polished. 
Fronds repeatedly dichotomous or trichotomous, the ultimate 
branches ending in a pair of pinne 3-12 in. long; a pair of smaller 
spreading or deflexed pinne is also placed at the base of the 
lower forks. Pinne lanceolate, acuminate, pinnatifid almost to 
the base. Segments close, spreading, 4-lin. long, linear, entire, 
obtuse or emarginate, glaucous beneath and sometimes pubescent 
on the costa, firm or more or less membranous, pale-green. Veins 
transversely spreading from the costa, each one pinnately divided 
from near the base into 3-6 veinlets. Sori solitary on an exterior 
veinlet, of 6-12 sporangia.—Hook. and Bak. Syn. Fil. 15; Hook. f.
