964 FILICES. [Adiantum. 
6. A. fulvum, Raoul, Choix de Plantes, 9.—Rhizome long, 
creeping, clothed with brownish subulate scales. Stipes 4-12in. 
long, erect, dark reddish-brown or almost black, rough with minute 
projections throughout, more or less scaly towards the base. 
Fronds 6-15in. long, 3-9in. broad, ovate-deltoid in outline, 
2-3-pinnate or rarely in large specimens 4-pinnate at the base, 
olive-green or pale-green, not glaucous beneath; rhachis and cost 
more or less densely clothed above with strigose fulvous hairs. 
Pinne 2-4 pairs with a long terminal one, in small specimens not 
branched, in larger ones the lowest pair and sometimes all again 
divided, or rarely the lowest pair twice branched. Pinnules 4-2 in. 
long, about +in. deep, petiolate, dimidiate, obliquely oblong, often 
slightly falcate; lower margin curved or nearly straight, entire; 
upper margin almost parallel, deeply crenate ; lower surface often 
minutely setulose with stiff fulvous hairs; texture firm but not 
coriaceous. Sori usually numerous in shallow notches at the tips 
of the lobes of the upper and outer margins, not in the sinuses 
between the lobes. Indusium orbicular-cordate, often pale when 
young.—Hook. Sp. Fil. ii. 52, t. 854; Hook. f. Fl. Nov. Zel. ii. 22;

Peninsula, not uncommon. 
Very close indeed to A. affine, with which it certainly seems to me to be 
connected by intermediate forms. It is more copiously branched, the rhachis 
and coste are clothed with strigose fulvous hairs, the stipes is minutely muri- 
cate, and the pinnules are narrower and subfalcate, and often setulose beneath. 
It is also found in Norfolk Island, New South Wales, and Fiji. 
12. HYPOLEPIS, Bernh. 
Rhizome usually wide-creeping. Fronds large, 2—3-pinnate or 
decompound, 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 cr reniform, membranous, composed 
of the modified margin of the trond, reflexed over the sorus and 
more or less covering it. Sporangia stalked, bursting transversely, 
with an incomplete vertical ring. 
Species 12, confined to the tropics and the south temperate zone. Of the 
three species found in New Zealand, two are endemic, the remaining one extends 
to Australia, Polynesia, and the Malay Archipelago. The genus only differs 
from Polypodiwm (as defined in the ‘‘Synopsis Filicum’’) by the sori being 
partly covered by an incurved lobule of the frond. 
Fronds (with the stipes) 2-5ft., deltoid, tomentose, 
4-pinnate. Pinnules crenate-toothed = .. 1. H. tenutfolia.
