Gen. V, Sp. 12. — Gen. VI, Sp. 6. 
inatifid ; stipes quite smooth, stiff. The pinnate frond distinguishes 
from II. polyanthos, and the smooth stipes, from H. scabrum . 
12. II. scabrum. Fronds darker coloured ; often hanging 
m trees, and attaining a great length ; always to be recognized 
| the scattered, stiff, deciduous, reddish-brown, hairs, on the stipes 
|i rachis. Bay of Islands. East Coast. Dense forests near 
pllington. 
13. II. jlabdlatum. A very bright green species, generally 
|nd on the trunks of tree-ferns ; 2-8 inches long ; somewhat re- 
abling H. demissum , but distinguished from it by having broad, 
-shaped, lower pinnae ; and light, soft, woolly, hairs at the base of 
> stipes, and on the rhizome.

14 . H. ceruginosum. Fronds pendulous, 3-10 inches long; 
little, branched, reddish, hairs, all over its surface, render this 
l unmistakeable. Waikare Lake. Dusky Bay. Wellington. 
15. H. Lycdlii. A very distinct little species ; stipes hair- 
e ; frond |-2 inches long, fan-shaped ; involucra sunk in the 
jx of the segments ; branching hairs round the margins. Thom- 
’s Sound. Middle Island. Huia, Manukau Heads. 
Gen. VL — Trichomanes. 
1. T. renifbrme . The simple, bright green, kidney-shaped 
ids, with their fringe of fructification, render this species quite 
ily recognised. Common, but peculiar to New Zealand. 
2. T. humile. Frond variable in shape, delicate in texture ; 
inches long, bi-pinnatifid ; involucra sunk in short segments ; 
iptacle generally very long and hair-like. On trunks of trees, &c. 
jrows in a small cave at the Three Kings, 
3. T. venosum. Pinnate and brighter in colour, otherwise 
ewhat resembling T. humile ; pinnae pinnate or pinnatifid, often 
ery irregular length. On wet rocks, trunks of tree-ferns, &c. 
4. T. Oolensoi. Hitherto only found in the dense forests 
• Waikare Lake. It appears to differ from the two last species 
ts distant, shortly stalked, pinnae ; and its involucre, which is 
ked, instead of being sunk in a segment. 
5. T. strictum. Fronds densely tufted ; stipes and rachis 
k and rigid ; frond pinnate ; pinnae very finely cut into 
lerous, very narrow, segments ; involucra stalked. This fern 
iry rare : it has been found in thick forests near the East Coast, 
at Dusky Bay, Massacre Bay, and Hokianga. 
6. T. elongatum A lurid-green, rigid, tufted species ; 4-9 
es high ; pinnae over-lapping each other, pinnate, with toothed
