Petiole sometimes viscid-glandular. Blades thick and leathery, abaxially densely white-farinose and viscid-glandular, adaxially viscid-glandular. Distal pinnae mostly entire. Proximal basiscopic lobes of basal pinnae entire to undulate or crenate. 2n = 60.
Habitat: Chaparral, pine and oak woodlands
Elevation: 50–500 m
Distribution
Largely coastal, Calif., Mexico in Baja California.
Discussion
Pentagramma triangularis subsp. viscosa was said to introgress with P. triangularis subsp. triangularis by K. S. Alt and V. Grant (1960), who noted both diploid and tetraploid plants of intermediate morphology at some sites where these two occur together.
