Electronic Flora of South Australia genus Fact Sheet

Family: Goodeniaceae

Citation: Smith, Trans. Linn. Soc. 2:346 (1794).

Derivation: After Samuel Goodenough, 1743-1827, Bishop of Carlisle, botanist and vice-president of the Royal Society.

Synonymy: Not Applicable

Common name: Goodenias.

Herbs, undershrubs and shrubs; leaves basal or cauline, usually flat, entire to pinnatipartite.

Inflorescence racemose, sometimes a thyrse or condensed almost into an umbel, rarely flowers solitary in axils of basal leaves; flowers often with a pair of small bracteoles, strongly zygomorphic, epigynous with a hypanthium; sepals 5; corolla shortly tubular, deeply split posteriorly, with an anterior nectary pocket or spur appressed to the ovary; lobes winged, unequal, the 2 posterior upcurved, often auriculate, more deeply cut than the anterior 3; stamens free, epigynous; anthers oblong; style simple or deeply 2-fid, glabrous to villous, shorter than the corolla; indusium square to transversely elliptic or ovate, 2-lipped, with bristles on the upper or both lips; stigma entire to emarginate; ovary inferior to semi-inferior, incompletely 2-celled with a dissepiment bearing few to many ovules.

Fruit a 2-valved capsule; valves often 2-fid; seeds endospermic, more or less flattened, with a distinct rim and/or a wing; caruncle absent.

Distribution:  About 170 species, almost all Australian, but extending to New Guinea and Indonesia.

Biology: No text

Taxonomic notes: Descriptions of Goodenia species were written by D. A. Cooke with the help of an unpublished draft revision by R. C. Carolin. Latin protologues of new species are entirely the work of R. C. Carolin.
