Grevillea

Silky oak Grevillea robusta in flower, photographed by Jan Smith.


Belongs within: Proteaceae.

Grevillea is a genus of about 270 species of trees and shrubs found in Australia and New Guinea. Some species are popular garden plants for their bright comb-like flowers. One such species is the largest member of the genus, the silky oak G. robusta, a native of coastal eastern Australia growing to over 30 m in height.

Characters (from Foreman 1995): Leaves spiralled to alternate, simple or pinnate, usually with differentiated upper and lower surfaces. Inflorescences terminal or axillary, panicles or raceme-like, sometimes with flowers borne on one side. Peduncles absent. Indumentum adpressed, hairs 2-branched or appearing to be attached near the middle. Flowers bisexual, pedicellate, in pairs, subtended by small, non-persisting bract; floral bracts absent. Perianth mostly recurved; limb oblique, globular, segments coherent at limb for some time after tube splits open. Anthers all perfect, ovate or oblong, sessile in concave limb segments; connective not usually prolonged. Disc fleshy, semi-annular or annular, mostly entire or sometimes more or less bilobed. Ovary shortly stipitate or sessile, 1-locular; ovules 2, hemitropous, attached laterally; style often elongated, protruding from slit on lower side of tube, retained for some time by coherent limb segments, eventually free; pollen presenter more or less dilated, straight, oblique or lateral and disc-like; stigma usually in centre of pollen presenter. Fruit a follicle, coriaceous to woody. Seeds 1 or 2, flat, orbicular or oblong, winged all around or occasionally wingless.
