DAVALLIA Nova-Zenanvia, Col. 
New Zealand Davallia. 
Davauiia Nove-Zelandie ; caudex long, creeping, hairy (not chaffy), as well as 
the lower part of the stipes and the axils of the primary pinne, with soft, 
copious, jointed, ferruginous hairs; fronds a span to a foot and more long, 
ovate, acuminate, tripinnate, membranaceous, but rather rigid, divisions all 
rather distant, finely cut, ultimate pinnules deeply pinnatifid, lanceolate ; 
segments ovato-lanceolate, falcate, cuspidato-acute, entire, or with one or 
two teeth; sori rather large, upon a lateral tooth, rarely in a sinus; invo- 
lucres subreniform, at length forced back from the enlargement of the sorus ; 
secondary rachises flexuose. .

Has. New Zealand, Northern Island, .4. Cunningham in Herb. Heward (D. his- 
pida, Hew. MS8S.). Common on the coast and in the interior, Colenso, 
n. 50, Stephenson, x. 121.—Cultivated at Kew. 
Quite distinct from any other Davallia, but allied to the East 
Indian D. cherophylla, Wall., and to D. affnis, J. Sm.; also an 
Indian species. In size most resembling the former. Caudex 
slender, creeping, hairy, or almost tomentose, with jointed, soft, 
ferruginous hairs, not at all scaly, sending down numerous, 
hairy, fibrous roots from beneath. Stipes six to eight inches 
high, mahogany-brown, glossy ; main rachis the same, flexuose 
and slender. Frond eight inches to a foot long, membrana- 
ceous, but very firm; thrice pinnated. Sori large in proportion 
to the size of the segments, often equal in breadth to the teeth 
on which they are placed. The colour of the frond is brownish- 
green, slightly glossy, much paler below. Mr. Heward had 
given a very appropriate name to this species in his herbarium, 
which we would gladly have adopted, but that Mr. Colenso’s 
name is published in the ‘ Tasmanian Journal of Science.’
