NortH Is~tanpd: Not uncommon from the Bay of Islands to the Hast Cape 
and Taranaki, from thence somewhat rare and local to Cook Strait, usually on 
calcareous or alluvial soils. SourH Isntanp: Nelson—Travers; near Foxhbill, 
T. F.C.; West Wanganui, Kingsley. Sea-level to 1800 ft. 
Also found in Australia and Tasmania, the Malay Archipelago, India, 
‘tropical Africa to the Canary Islands, the Azores, and Madeira. 
12. A. japonicum, Thunb. Fl. Jap. 334.— Rhizome long, 
slender, creeping, branched, densely scaly at the tip. Stipes 3-9 in. 
long, slender, pale-brown or straw-coloured, scaly when young, 
especially near the base. Fronds 6-12 in. long without the stipes, 
24-5in. broad, ovate-lanceolate, long-acuminate, pale-green, thin 
and membranous, glabrous on both surfaces or sprinkled with a 
few weak hairs, pinnate below, pinnatifid towards the apex; rhachis 
slender, slightly scaly. Pinnz spreading, rather distant, 14-3 in. 
long, lanceolate, acuminate, deeply pinnatifid; lobes about in. 
long, close, oblong, obtuse, slightly toothed or nearly entire. Veins 
pinnate in the lobes; veinlets 4-6 on each side, simple or forked. 
Sori linear-oblong, usually occupying all the veinlets, reaching two- 
thirds of the distance from the midrib to the margin, the lowest one 
in each lobe usually diplazioid.—Hook. and Bak. Syn. Fil. 234;

This appears to be a widely distributed species, ranging through Polynesia 
to the Malay Archipelago, India, China, and Japan. It is possible that 
Mr. Kirk’s A. umbroswm var. tenuifoliwm (Trans. N.Z. Inst. xxiii. 424), of 
which I have seen no specimens, may be identical with it. 
19. ASPIDIUM, Swartz. 
Rhizome short and erect or ascending, or long and creeping. 
Fronds tufted at the top of the rhizome or more or less distant 
along it, very variable in size cutting and venation, 2—3-pinnate or 
pinnate, coriaceous, more rarely submembranous; veins free in all 
the New Zealand species. Sori globose, dorsal, placed on the back 
or at the tip of a vein, or at the junction of two veins. Indusium
