Genus Lomatia Family Proteaceae
Common Name: Crinkle Bush

Description: Shrubs or small trees.

Leaves alternate, simple to bipinnate, margins entire or toothed to deeply pinnatisect.

Conflorescences raceme-like or paniculate, terminal or axillary, usually much longer than the leaves; flowers pedicellate in pairs, bracts caducous. Flowers zygomorphic. Perianth tube slit by the style on the lower side while in bud. Anthers sessile. Hypogynous glands 3, or occasionally the fourth present but small. Ovary stipitate, glabrous; ovules several, in 2 rows; style long and dilated apically into a pollen presenter.

Fruit a follicle, ± leathery; seeds several, flat with a terminal wing, a yellow powdery substance between the seeds.

Distribution and occurrence: World: 12 spp., S.Amer. & Aust. Aust.: 9 spp. (endemic), Qld, N.S.W., Vic., Tas.

All species of Lomatia show considerable variation, so that it is sometimes difficult to separate them. The situation is further complicated by hybridization that frequently appears to occur when 2 species are found growing together in the field.
