Tribe IV— VII. Gen. XXVIII— XXXV. 
woolly appearance. Frond simple, leathery. Sori numerous, round, 
protruding through the white covering. 1 Species. 
Gen. XXVIII. Grammitis. Sori oblong or linear, naked, in 
Dne series on each side of the costa to which they are oblique ; 
veins immersed in the simple frond. 1 Species. 
Gen. XXIX. Gymnogramma. Sori naked occupying the 
veins and veinlets, hence often running in lines and forking, or 
covering the spaces between the veins and forming a mass of fruc- 
tification. 2 Species. 
Gen. XXX. Notholaena. The only New Zealand species 
very much resembles Cheilanthes ternuifolia , but may be distin- 
guished by its scaly, hairy frond ; sorus marginal, naked, but 
.ometimes partially concealed by the margin of the frond. 
I Species. 
Tribe V. — Schiz^ee^e. 
Gen. XXXI. Lygodium. A remarkable genus of creeping, 
viry ferns ; fertile and barren fronds differing in form ; fertile 
ronds repeatedly branching dichotomously, the stalk thus 
-ividing three or four times between its point of junction with 
he stem and its fertile lobes, the leafy part of which is very incon- 
picuous, being almost concealed by the numerous little spikes of 
ructification with which they terminate. 1 Species. 
Gen. XXXII. Schizsea. A very curious geaus to be distin- 
guished by the small pinnatifid limb or comb with which each frond 
>r each pinna terminates, and on which the capsules are arranged in 
wo series, partially covered by its incurved margin. Ferns of 
his genus often have the appearance of withered stalks, with a 
ittle brown comb of fructification at the top. 3 Species. 
Tribe VI. — Osmunde^e. 
Gen. XXXIII. Leptopteris. The New Zealand ferns of this 
;enus are very finely cut, bright green and translucent. Capsules 
cattered over the back of the frond on the veins. 2 Species. 
Gen. XXXIV. Todea. May be distinguished from Leptopteris 
y its fronds being very thick in texture. 1 Species. 
Tribe VII. — Marattie^e. 
Gen. XXXV. Marattia. Sori of very curious structure placed at 
tie ends of the veins, just within the margin, and consisting of two 
pposite, parallel, plates which are marked within by transverse
