Pigea

Ging.

Mém. Soc. Phys. Genève 2: 27,28 (1823)

Taxonomic status Accepted

Occurrence status Present

Establishment means Native

Degree of establishment Native

Perennial herbs or shrubs, (in Victoria) glabrous. Leaves alternate or in clusters, rarely opposite, sessile or petiolate, entire to toothed; stipules present or absent. Inflorescence axillary or terminal, flowers solitary or in raceme or cyme. Sepals subequal; petals unequal, lower petal longer than others, spurred, clawed, with broad lamina, lower pair linear, lateral pair broader; staminal filaments short, anthers free but cohering by narrow wings, often with appendages, the 2 lowermost anthers with basal nectaries; ovary globose, style clavate, curved at the apex. Fruit a capsule, coriaceous, glabrous, dehiscing into 3 boat-shaped valves; seeds 2–5 per valve, smooth, pitted or reticulate.

In resurrecting Pigea, Forster 2021 recognised 31 species, treating the genus as a synonym of Afrohybanthus Flicker, a genus of the paleotropics (Africa, Madagascar, southern Asia, northern Australia and the SW Pacific). However Wahlert et al. (2014) and subsequently Flicker and Ballard (2015) considered Pigea to comprise a monophyletic group of species from temperate Australia and islands of the South Pacific. In this more restricted sense, Pigea comprises 10 species from Australia and 3 (not yet transferred to that genus) from South Pacific islands.
