Description

Plants in the genus Gompholobium mostly have leaves composed of three separate leaflets but some species have simple leaves and others have pinnate leaves. The leaflets are arranged alternately along the stems and are usually narrow and have smooth edges. The flowers are usually arranged in groups on the ends of the branches, sometimes singly or in pairs. The sepals form a short tube with five lobes longer than the tube. The large "standard" petal at the back of the flower is circular to kidney-shaped and is larger than the other petals. There are ten free stamens and the ovary is glabrous. The fruit is an oblong to almost spherical legume containing two to many ovules.[3][4]

Taxonomy and naming

The genus Gompholobium was first formally described in 1798 by James Edward Smith and the description was published in Transactions of the Linnean Society of London.[1][5] In 2008, Gompholobium grandiflorum was designated the lectotype.[2] The genus name is derived from the Ancient Greek words gomphos, meaning "bolt", "peg", or "nail"[6]:545 and lobos meaning a "capsule" or "pod"[6]:118 referring to "the inflated shape of the seed pods".[7]

Distribution

Glory peas are found in all states of Australia.

Ecology

Toxicity of plants of the genus was suspected and proven to be fatal to sheep, goats and other livestock introduced by the pastoralists at the Swan River Colony. This was reported by James Drummond in Hooker's London journal of botany 1842.[9]
