Common name


Rhizome short, creeping, up to 7 mm in diameter; rhizome scales linearin outline, subentire, up to 5 mm long pale chestnut to dark brown. Fronds monomorphic, tufted, erect to suberect, 4-8, 10.5-90 cm tall, coriaceous. Stipe6-50 cm long, black, shining, with a few brown scales near the base. Lamina pinnate in the distal half of the lamina with a single pinna on the top resembling the lateral pinnae, to 3- to 2-pinnate on the lower pinnae, sharply triangular in outline, 4.5-40 x 13-43 cm; pinnae with 5-7 pairs of pinnules; ultimate segments narrowly triangular to lanceolate in outline, forming a long drawn out point, rounded to cordate base articulated to a short black petiole, glabrous on both surfaces; veins hardly visible, anastomosing; rhachis, secondary rhachis and petioles black, with short brown hairs on the upper surfaces. Sori marginal, continuous to within a few milimeters of the apex and petiole; indusium entire, membranous, continuous.


Can be seperated from Cheilanthes virides by the articulated pinnae, the obscure and anastomosing venation, the basiscopical developed basal pinnae.


angulosa: strongly angled; an allusion to the sharp angles created by the rhachis, secondary rachises and pinnules.


In tall, evergreen forest dominated by Chrysophyllum gorungosanum, on moist forest floor where an opening in the forest canopy occurs, evergreen forest in rocky places.
