high, bright green above, usually glaucous below, 3-piunate ; stipes and 
racliis glabrous, polished, channelled, pale brown ; pinnae ascending, lower 
opposite ; secondary lanceolate, again pinnate or pinnatifid ; segments linear- 
oblong, subacute, notched. Involucres in the notches of the segments, point-

low) ; Coromandel, Mrs. Jones (fronds always white below). The only species of the genus, 
not found elsewhere. 
8. CYSTOPTERIS, Bernhardi. 
Delicate, flaccid ferns. Rhizome short, creeping. — Fronds tufted, pinnate 
or 2-pinnate. Veins pinnate and forked ; veinlets free. Sori small, globose, 
on the back of the pinnules, inserted on the middle of a venule, distant 
from the margin. Involucre very membranous, attached by a broad base to 
the veinlet below the sorus, ovate or oblong, very convex, acute ; margin 
jagged, at length reflexed. Capsules pedicelled, with a dorsal striate ring. 
A small genus of ferns, natives of mountainous, cool, damp regions in the northern and 
sou*hern hemispheres. 
1. C. fragilis, Bernliardi. Fronds 3-6 in. high, lanceolate or oblong- 
lanceolate, pale green, pinnate or 2-pinnate ; stipes slender, brittle, glabrous ; 
rachis winged above, primary pinnae rather remote, oblong or lanceolate, sim- 
ple or again pinnate ; pinnules incised and lobed, upper decurrent. — Hook. 
Sp. Fil. i. 198; FI. Tasman, ii. 136. t. 166. 
Northern Island : Mount Egmont, ranges ( Mrs. Jones). Middle Island : Wairau 
and Kaikora mountains, alt., 3600 ft., Travers , Sinclair ; Southern Alps, alt. 3000 ft., 
Haast ; Otago, lake districts, Hector and Buchanan. 
9. DAVALLIA, Smith. 
Rhizome creeping in the New Zealand species, tufted in many others. 
— Frond compound, rarely simple. Veins pinnate, simple or dichotomous. 
Sori oblong or rounded, on or near the margin. Involucre coriaceous, super- 
ficial, arising from the tip of a vein, its base and usually its sides too, adnate 
to the surface of the frond, opening outwards. Capsules pedicelled, with a 
dorsal striate ring. 
A large tropical and subtropical genus, of often very handsome ferns. 
1. D. novae-Zelandiae, Col .; — FI. N. Z. ii. 19. Rhizome creeping, 
woody, hispid. Frond 3-24 in. high, 3-pinnate, ovate or oblong, acuminate; 
stipes red-brown, polished, glabrous above, hispid below; rachis glabrous, 
polished, sometimes hairy in the axils ; pinnae stipitate, linear-oblong, acumi- 
nate ; secondary ones oblong-lanceolate, with pinnatifid incised tips ; ultimate 
stipitate, \ in. long, sharply cut. Involucre orbicular or broadly ovate, 
jagged, attached by a broad base. — Hook. Sp. Fil. i. 158. t. 152; Garden
