Arctostaphylos stanfordiana Parry

Morphology

provided by EOL authors

Arctostaphylos stanfordiana is a woody shrub with a stature of one half to two meters in height. This species lacks any basal burl and manifests stems and twigs that are glabrous or finely glandular-bristly (rarely puberulent).

Leaves are erect with four to twelve millimeter petioles and blades three to five centimeters in length and 1.5 to 2.5 cm wide; moreover, each leaf is generally elliptic or oblanceolate, with wedge-shaped or obtuse base. Leaf margins are entire, with upper and lower surfaces alike, bright green to slightly glaucous, generally shiny, glabrous, smooth (finely glandular-puberulent, finely scabrous in subspecies ''raichei''). The inflorescence is open with scale-like bracts 1.0 to 1.5 millimeters; moreover, the bracts are deltate and acuminate. Pedicels are glabrous. Corollae are typically a deep pink and the ovary is smooth. Asymmetric glabrous fruits are six to eight mm wide.
