Common names:
Frequency: Rare
Status: Native
Rhizome short, creeping, up to 7 mm in diameter; rhizome scales dark brown, subentire, linear, up to 5 mm long. Fronds tufted, erect to suberect, coriaceous. Stipe black, shining, up to 44 cm long, with a few brown scales near the base. Lamina sharply triangular in outline, c. 40 mm long and almost as broad at the base, 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. Ultimate segments lanceolate in outline, forming a long drawn out point, 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.
Notes: Can be seperated from Cheilanthes virides by the articulated pinnae, the obscure and anastomosing venation, the basiscopical developed basal pinnae.
Derivation of specific name: angulosa: strongly angled; an allusion to the sharp angles created by the rhachis, secondary rachises and pinnules.
Habitat: In tall, evergreen forest dominated by Chrysophyllum gorungosanum, on moist forest floor where an opening in the forest canopy occurs.
Altitude range: (metres) 1370 - 1400 m
