We found that unicellular papillate
hairs were scattered on gametophytes, and this is likely a stable characteristic of the Polypodiaceae (Nayar and Kaur, 1971).
The gametophytes of Elaphoglossum decursivum share the same general morphology of most other species of the genus, the most prominent characters being the elongate, strap-shaped thallus and presence of papillate, glandular hairs on the margins and surface (Chiou et ah, 1998; Nayar and Kaur, 1971; Stokey and Atkinson, 1957).
papillate hairs and proscales) found on the very young leaves of Elaphoglossum decursivum represent the first observation of such indument in sect.

In this type, the apical cell of the germ-filament produced a unicellular papillate
trichome crowning it.
Gynoecium bicarpellate, syncarpous, superior, usually unilocular and oriented in the antero-posterior plane; surrounded by nectary-disk or distinct glands; placentation parietal (this occasionally bifid) or rarely free axile, seldom bilocular with axile placentation: style simple and terminal, with entire or bilobed, papillate
stigma, rarely style wanting and stigmas decurrent on ovary (Lomatogonium); ovules usually numerous and anatropous.

9 mm SL in males; body deep and moderately compressed; dorsal profile slightly concave to nearly straight on head, convex from nape to end of dorsal fin base; ventral profile convex, slightly concave on caudal peduncle posterior to dorsal and anal fins; maximum body height occurring at the base of the pelvic fins; dorsal and anal fins shallow and rounded, tips with short filamentous rays; dorsal and anal fins with papillate
contact organs, distributed over fin rays; pelvic fins shorts, tips reaching the anus; caudal fin subtruncate; branchiostegal membrane projecting from opercle, distal edge slightly wrinkled.
