This was founded on an incomplete specimen but is apparently a very di- 
stinct species. The original specimen consists of the lower half of a lamina with 
a part of the stipe, which is stramineous and glabrous. Lowest pair of pinnze 
deflexed and below them a pair of auriculiform pinnz. Pinne opposite, sessile, 
12 cm long by 2 cm broad, acuminate, thinly herbaceous, the costz above pilose, 
cost, costule and veins beneath long- and soft-hairy by whitish, thin, pluri- 
cellular hairs, the coste besides furnished with a few small, red, thin scales. 
Rachis stramineous, deciduously hairy. Segments close, connected by a wing 
1'/2 mm broad, bluntly rounded at the apex, the margins obscurely crenate, ciliate, 
6—7 mm broad, the lower pair not reduced. Veins simple, 8-jugate. Sori medial, 
reddish, exindusiate. 
D. baniensis Ros. based on a single leaf with a pinnatifid apex is quite 
the same.
