338 Ferns of British India and Ceylon. 
digitately dichotomous, dark brownish-green above, pale and tawny 
beneath, segments 4-8 inches long, scarcely half an inch wide, linear- 
sublanceolate, finely acuminated costate entire ; venation manifest, 
the costules form a costal series of large soriferous areoles, the rest of 
the veins unite, constituting lesser areoles and include free veinlets ; 
sori 1-2 in each primary areole (sometimes confluent) in a single 
series very near the costa. Hook. Sj>. Fil. v. 100. Hook, in Kew

GENUS LXIV.— DRYNARIA. {Bory.) 
{Dryads, the sterile fronds being like oak-leaves, a tree sacred to the 
Dryads.) 
Fronds articulate with the caudex, with either a separate sterile 
frond Hke an oak leaf, or the base of the frond pinnatifid and oak- 
leaf-hke ; veins copiously anastomosing, forming quadrate or hex- 
agonal areoles ; sori small, round or oval, numerous 
I. Drynaria CORONANS. {Wall.) Rhizome thick, creeping, 
branched and interwoven, villous-paleaceous with golden scales ; 
fronds large uniform, when growing arranged in a circle, firm, coria- 
ceous, but rather thin and translucent, two and more feet long, from 
a broad sessile cordate, lobate-pinnatifid base (then suddenly con- 
tracted), lanceolate, deeply almost to the rachis pinnatifid, segments 
8-12 inches long, f-i inch and more wide, oblong-lanceolate, acu- 
minate, lower ones gradually shorter, entire, incrassated at the margin ; 
venation very manifest, costules parallel extending to the margin, 
these are connected by transverse veins forming 5-6 soriferous areoles 
and then again generally two or three others which include free 
veinlets; sori oval, often confluent longitudinally, solitary in the 
primary areoles, forming an eccentric series always nearer one costule 
than the opposite one. Wall. Cat. n. 288. Hook. Sp. Fil. v. 94.
