1022 FILICES. [Schizea. 
NortH anp SoutH IsuAnps, CHATHAM IsLANDS, AUCKLAND. IsLaAnDs: The 
typical form not uncommon in barren clay soils throughout the North Island, 
apparently rare and local to the south of Cook Strait. Var. australis: Cold 
peaty localities in mountain districts from Moehau (Cape Colville) southwards, 
descending to sea-level in Stewart Island and the Auckland Islands. Sea-level 
to 4000 ft. 
Also in Australia and Tasmania, New Caledonia, Madagascar, Chili, and the 
Falkland Islands. S. australis is clearly only a depauperated form, connected 
with the type by transitional stages. 
2. S. bifida, Swartz, Syn. Fil. 151.—Rhizome very short, stout, 
creeping. Fronds close together along the rhizome, not distinct 
from the stipes, 6-12 in. high or more, about =, in. diam., rigid, erect, 
wiry, more or less scabrous, somewhat flattened, with a prominent 
midrib and narrow thick wing on each side, usually forked at or 
below the middle, rarely undivided, the branches sometimes forked 
a second time. Fertile segments terminating the branches, 4-3 in. 
long, erect or slightly recurved, rather broader than in S. fistulosa, 
of 10-20 closely placed pinne on each side. Pinne all turned 
to the one side, 4-4in. long, linear, fringed with long cilia. 
Sporangia in 2 closely placed rows, rather smaller than in 
S. fistulosa.—A. Rich. Fl. Nowv. Zel. 95; A. Cunn. Precur. n. 169 5.

(Type BOs ees 
Norra Istanp: On sterile clay or pumiceous soils from the North Cape to 
Cook Strait, but often local. SourH Istanp: Nelson—Takaka and Paramahoi,. 
Kingsley. Sea-level to 2000 ft. 
Also in Australia and Tasmania. Unbranched specimens are best dis- 
tinguished from S. fistulosa by the scabrous frond and broader fertile segment. 
3. S. dichotoma, Swartz, Syn. Fil. 151.—Rhizome short, stout, 
creeping. Fronds-few or many, close together, 6-14 in. long, erect,. 
rigid, wiry; lower portion or stipes angular, channelled in front ; 
upper portion repeatedly dichotomous, forming a flabellate or 
deltoid frond 2-4 in. across or more; branches flattened, ;,—-;51n. 
broad; midrib stout, evident ; margins sometimes minutely toothed 
towards the tip. Fertile segments terminating the branches, dis- 
tinctly stalked, erect or inclined, +-tin. long, consisting of 4-10 
spreading pinne on each side; pinne }-+in. long, linear, fringed 
with long hairs. Sporangia in two closely placed rows.—Hook. and 
Grev. Ic. Fil. t. 17; A. Cunn. Precur. n. 170; Raoul, Chotxw, 37; 
Hook. f. Fl. Nov. Zel. ii. 47; Handb. N.Z. Fl. 385; Hook. and
