Norru Istanp: Three Kings Islands, abundant, 7. F. C. 
Very close to the northern D. canariensis L., but stouter and more coriaceous, 
and not so finely cut. 
15. LINDSAYA Dryander. 
Usually small subcoriaceous bright-green ferns. Rhizome creeping ot 
short and tufted. Fronds pinnate or 2-3-pinnatifid ; pinnae often 1-sided. 
Veins tree, or anastomosing in a few species not found in New Zealand. 
Sori forming a continuous or more or less interrupted line within the 
margin of the frond and parallel to it, placed at the apex of 2 or more veins 
and uniting them. Indusium apparently double and 2-valved, opening 
outwards ; upper valve formed of the more or less altered margin of the 
frond; lower valve thin, membranous, continuous. Sperangia numerous, 
stalked, bursting transversely ; ring vertical, incomplete. 
Understood in the sense of the “Svnopsis Filicum,” this is a genus of about 
75 species, mainlv found in the tropics of both hemispheres. Two of the New Zealand 
species extend to Australia, Tasmania, and Polynesia, one of them reaching New 
Caledonia as well, the remaining one is endemic.

Fronds 2-3-pinnatifid, dark-green, oblong-lanceolate, broadest at 
the base ; ultimate segments obovate, rounded at the tip .. 2. L cuneata. 
Fronds 2-3-pinnatifid, pale-green, lanceolate, not broadest at the

1. L. linearis Swartz Syn. Fil. (1806) 118, 318, t. 3—Rhizome slender, 
creeping, clothed with yellowish-brown scales. Stipes 2-9 in. long, slender, 
flexuous, wiry, dark red-brown, smooth and shining. Fronds 3-8 in. long, 
about din. broad, narrow-linear, membranous, pinnate; barren ones 
shorter and broader than the fertile, often prostrate ; fertile always erect ; 
rhachis naked, glossy. Piunae of the fertile froads 4-din. long, flabellate 
or cuneate, sessile or nearly so, not lobed or very indistinctly sc, revolute 
when dry. Sori forming a continuous line along the upper edge. Indusium 
broad, membranous; both valves minutely and irregularly laciniate. 
Pinnae of the barren fronds 4-4 in. leng or more, deeply lobed or incised.

NortH Aanp Sovuru Is~tanps, Stewart Istanp, CHATHAM ISLANDS. From the 
North Cape southwards, usually on clay hills or in cold swampy soils, most plentiful 
to the north of the East Cape, rare and local in the South Island. Sea-level to 
2069 ft. 
Also iound throughout the whole of eastern Austrclia and Tasmania, in Norfolk 
Island, and in New Caledonia. Mr. Colenso’s L. trilobata, which appears to be the most 
abundant state in New Zealand, only differs in the pinnae of the barren frond being 
rather more deeply lobed than usual.
