gradually tapering below and decurrent upon the stipes, costules 
distinct, elevated on the under side ; sori immersed, very minute and 
numerous, arranged in compact closely placed lines or series between 
the costules and in equally-compact series transversely with them ; 
areoles in about 10 series between the costa and margin, each in-

wide, broad-lanceolate or oblanceolate, sharply acuminated below, 
gradually and much attenuated upon the stipes, glabrous above, 
minutely sellate-tomentose beneath, the tomentum thin, firm and 
close so as to appear subfurfuraceous or compactly pannose of a 
whitish colour, costa stout, costules evident but not elevated ; vena-

15-20 in a series between the costa and the margin, each with
