152 FLORA OF TASMANIA. [ Filices. 
Distri. East and West Australia, New Zealand, North and South Africa, extratropical South 
America, the Himalaya Mountains, and shores of the Mediterranean, Jersey. 
This beautiful little Fern is remarkable for its wide geographical distribution in the northern hemisphere.— 
Fronds an inch to a span high, perfectly glabrous, membranous and shining, pale-green, oblong-lanceolate, bi-tripin- 
natifid. Pinnules 2-4 lines long, obovate-cuneate, twice or thrice lobed or crenate, the lobes blunt. Partial rachis 
winged. Stipes and main rachis usually red-brown, brittle, shining, grooved in front. 
Tribe V. Scu1zaum.—Sori arranged in imbricated spikes, or on resupinate divisions of the frond. - 
Capsules sessile, striated at the apex (the horizontal ring being terminal). 
Gen. XXI. SCHIZAA, Sm. 
Capsule ovoidex, basi insertee, reticulatee, apice striatee, secus lacinias lineares incurvas frondis resu- 
pinate biseriatim insertee. Indusium nullum v. e margine laciniarum inflexa formatum.— Rhizoma repens, 
breve, squamosum. Frondes cespitose, erecta, simplices v. dicholome ramose, filiformes, sulcate, sepius 
eristam terminalem profunde pinnatifidam gerentes; pinnis linearibus, conniventibus, pagina superiore sori- 
feris. : 
A very curious genus, rare in the north-temperate zone, common in the south-temperate and tropics. The 
species have erect, generally simple, sometimes dichotomously or flabellately branched, linear, flattened or filiform 
fronds, which bear at their apices a small, inclined, pinnatifid limb or comb, upon whose divisions the capsules are 
arranged.— Capsules in two series, close together on each side of the costa of each division, partially covered by the 
incurved margin, ovoid, sessile by the broad end, reticulated, striated at the smaller end, bursting laterally. Spores 
with rounded angles.— The fructification deceptively appears borne on the upper surface of the frond in this genus, 
the upper portion of the latter being resupinate ; the groove of the stipes, which indicates the true upper surface, 
will be found on the opposite side from the capsules. (Name from oxılw, to divide ; from the split frond.) 
1. Schizza bifida (Sw. Fil. 151); frondibus simplicibus dichotomisve asperulis subsemiteretibus, 
pinnis 8-16-jugis margine lacero-crinitis.— Br. Prodr. 162 ; Schnizlein, Icon. t. 24; Fl. N. Zeal. ii. 4T.

Disrris. Australia, New Zealand, East Indies, tropical America, Antarctic Islands. 
Rhizome short, stout, subterranean, thickly covered with red-brown paleaceous hairs. Fronds numerous, 
tufted, wiry, erect, rough to the touch, a few inches to 13 foot long, simple or once branched, semiterete, grooved 
on one side. Comb or appendix reclined, of eight to ten pairs of pinne, with laciniate-crinite edges.—The S. aus- 
tralis of Auckland Island seems to be a small variety of this species. 
Tribe VI. OSsMUNDACE®.—Sori naked. Capsules stalked, with a broad, dorsal, incomplete ring, 
bursting vertically. 
Gen. XXII. TODEA, Willd. 
Capsule pedicellate, globose, nude, annulo dorsali brevi lato, superficie inferiore frondis sparse, 
venis simplicibus furcatisve insidentes. Spore ovoidee.—Frondes fasciculata, coriacee. 
The only Tasmanian species of Todea is a tall, handsome, tufted Fern, with glabrous, bipinnate, coriaceous 
fronds, the lower pinnz on each division of which are generally densely covered with large, crowded, pale-brown
