Frangula californica subsp. cuspidata
Phytologia 76: 449. 1994.
Endemic
Basionym: Rhamnus cuspidata Greene Leafl. Bot. Observ. Crit. 1: 64. 1904
Synonyms: Frangula viridula (Jepson) Grubov R. californica subsp. cuspidata (Greene) C. B. Wolf R. californica var. viridula Jepson R. tomentella subsp. cuspidata (Greene) J. O. Sawyer
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.
