Petiole chestnut brown to dark brown, somewhat shiny, glabrous or sometimes viscid-glandular or rarely somewhat white-farinose proximally. Blade thin and herbaceous to thick and leathery, abaxially densely farinose, farina white or yellow, adaxially bright green to yellowish green when fresh, glabrous to glandular or viscid.
Habitat: Chaparral, pine and oak woodlands.
Elevation: 100–900 m
Discussion
Pentagramma triangularis occurs in rock crevices and at the base of overhanging boulders in drainages and on slopes and roadbanks. Occasional plants in which the farina is nearly absent may be encountered. These have been described as Pityrogramma triangularis var. viridis Hoover, a name of uncertain application that appears to refer to misshapen-spored hybrids of various parentage within the Pentagramma triangularis complex.
Selected References
