Extends northwards through Australia to the Malay Archipelago, India, and 
China. The typical state is easily distinguished from the following species by the 
broad deltoid frond, but intermediates are occasionally seen. 
2. €C. Sieberi Kunze in Pl. Preiss. ii (1847) 112.—Rhizome short, 
stout, creeping, clothed with chestnut-brown scales. Stipes 3-9 in. long, 
densely tufted, erect, wiry, dark chestnut-brown, polished, glabrous or 
with a few fibrillose scales. Fronds 3-9 in. long, 3-14 in. broad, linear- 
oblong or linear, erect, rigid, glabrous, 2-3-pinnatifid; rhachis smooth, 
glossy. Primary pinnae 3-15 opposite pairs, ascending, the lower rather 
remote, 5-lin. long, ovate-deltoid. Pinnules oblong, deeply pinnatifid ; 
segments entire or cuneate, margins much recurved when dry. Sori 
roundish or oblong, distinct, or ultimately confluent and continuous round 
the margins of the pinnules. Indusium usually elongated, narrow ; margins 
pale, entire or minutely denticulate.—Hook. Sp. Fil. 11 (1858) 83, t. 973;

NortH AnD Soutu Istanps: From the North Cape southwards, not uncommon 
in dry rocky places. 
Abundant in Australia, and also found in New Caledonia and the Isle of Pines. 
25. HYPOLEPIS Bernh. 
Rhizome usually wide-creeping. Fronds large, 2-3-pinnate or decom- 
pound, often glandular or tomentose ; texture membranous or herbaceous. 
Veins forked, free, never anastomosing. Sori small, globose, distinct, placed 
in the sinuses of the ultimate divisions of the frond. Indusium orbicular 
or reniiorm, membranous, composed of the modified margin of the frond, 
reflexed over the sorus and more or less covering it. Sporangia stalked, 
bursting transversely, with an incomplete vertical ring. 
Species 24, confined to the tropics and the South Temperate Zone. Of the 3 
species found in New Zealand, 2 are endemic, the remaining 1 extends to 
Australia, Polynesia, and the Malay Archipelago. The genus only differs from the 
Phegopteris section of Dryopteris by the sori being partly covered by an incurved 
lobule of the frond. 
Fronds (with the stipes) 2-5 ft., deltoid, tomentose, 4-pinnate.

Fronds (with the stipes) 9-24 in., deltoid, almost glabrous, 3-pin-
