64 FILICES. [ Gymnogramme. 
As defined above, this is a heterogeneous assemblage of over 100 species, differimy 
greatly from one another in habit, venation, and the arrangement of the sori, and often 
split up by authors into several small genera. Under this system G. rutaefolia would 
fall into the genus Plewrosorus, while G. leptophylla,. with a few allied plants, would 
constitute the genus Anogramma. But in a small flora like that of New Zealand it 
seems inadvisable to encourage the multiplication of closely allied small genera, only 
separated by comparatively trivial characters. 
Perennial. Fronds pinnate or 2-pinnatifid, subcoriaceous, densely 
clothed with ferruginous woolly hairs G. rutaefolia.

1. G. rutaefolia Hook. and Grev. Ic. Fil. (1829) t. 90.—Rhizome short, 
thick, erect or ascending, clothed with blackish-brown lanceolate scales. 
Stipes +-lin. long, stout or slender, everywhere densely villous with soft 
ferruginous woolly often glandular hairs. Fronds 1-3in. long by about 
+in. broad, linear-oblong, obtuse, subcoriaceous, pinnate; both surfaces 
densely clothed with soft ferruginous or silvery-brown woolly hairs, many 
of which are glandular-tipped. Pinnae alternate, rather distant, 1-4 in. 
long, obovate or rhomboid or fiabellate, shortly stipitate and obliquely 
cuneate at the base, the lowermost with 2-3 shallow lobes or rarely pinna- 
tifid. Veins flabellate. Sori linear-oblong, occupying most of the veins 
of the under-surface, distinct at first, but often confluent in age.— Hook.

Also widely distributed in Australia and Tasmania. It is united by most authors 
to the European @. Pozoz, which, however, seems to me to differ in the more slender 
habit, in being much less densely villous, the hairs seldom glandular, and in the narrower 
oblong (not obovate or flabellate) pinnae. 
2. G. leptophylla Desv. Journ. Bot. i (1813) 26.—Slender, delicate, 
-annual, 1-6in. high. Roots fibrous. Stipes $-3in. long, slender, brittle, 
smooth, glossy, bright chestnut-brown. Fronds 1-3 in. long, 4—-1in. broad, 
ovate or ovate-oblong to oblong-lanceolate; the outer spreading, much 
shorter and broader, usually sterile; the inner longer and narrower, fertile, 
erect ; pale-green, shining, thin and membranous, quite glabrous, 2—3-pin- 
nate. Pinnae alternate, stipitate, }-}in. long, again pinnate; secondary 
rhachises margined throughout. Pinnules few, obovate-cuneate, 2—3-lobed 
or -partite; lobes linear or linear-oblong, obtuse. Veins forked, a single 
veinlet only to each lobe. Sori oblong or linear-oblong, usually a single 
one to each lobe, often becoming confluent and covering the whole pinnule.—
