Latest revision as of 19:14, 5 November 2020

Leaf blades green adaxially, elliptic, 2–5(–6) cm, margins sharply serrate to dentate-serrulate with gland-tipped teeth, sometimes strongly revolute, apex abruptly acuminate to acute, abaxial surface sparsely to moderately densely white stellate-hairy, with intermixed longer, simple, erect hairs at least along veins, adaxial surface glabrous or sparsely hirsutulous; veins not prominent abaxially. Drupe stones 2.


Phenology: Flowering Apr–Jun.
Habitat: Chaparral, desert scrub, montane woodlands.
Elevation: 400–2300 m.

Discussion

When present, the strongly revolute leaf margins of subsp. cuspidata contrast with those of other taxa of Frangula californica. Plants identifiable as subsp. cuspidata but with flat-margined leaves perhaps show the influence of subsp. tomentella.

Selected References

None.
