thick coriaceous, quite opaque, sometimes with black dots on the back, 
naked on both faces, rarely with a few a sealelets along the 
rhachis, linear-lanceolate, entire, 6—12' X '/s—5/s', gradually tapering at 
both ends, sometimes forking at the apex. Veins hidden, anastomosing, 
forming 3 oblique sets of angular meshes on each side, the first two with 
appendages. Sori confined to the upper portion of the frond, on projecting 
angles or inner anastomoses of the second set of meshes, large, round 
or oblong, 11/2——21/2” in the longest diameter, immersed, with corresponding 
to t n y

scales. Stip. 1—4/ distant, pale, naked, 3—8‘ long. Frond thin charta- 
ceous, naked, hastately 3-lobed, with a deeply sinuose- cordate or shallow 
reniform base, 6—12‘  5—14’, the lobes long acuminate, the lateral ones 
rounded at the base and sometimes overlapping, or produced into acute 
auricles. Veins very prominent, a costa to each lobe, anastomosing 
(nervatio Drynariae). Main veins at oblique angles to the costa, sub- 
parallel, a their perpendicular branches forming rectangular meshes 
which are again subdivided into 2, 3 or more rectangular areoles with 
vacate branching appendages. Sori pale, small, very numerous, often 
ne at the swollen end of each appendicular branch or at their junctions. 
“ss angia few, with 12—14 joints. Spores ovoid-reniform, with one dorsal 
line which bifurcates at one or both ends. Five fib. vas. fascicles. —
