Overview:
Gompholobium, commonly known as glory peas or wedge-peas, is a genus of plants in the pea family Fabaceae and is endemic to Australia
Most species have compound leaves composed of three leaflets and all have ten stamens which are free from each other and a distinctive arrangement of their sepals
Common name: Glory Peas
Conservation status: ...
Etymology:
The genus name is derived from the Ancient Greek words gomphos, meaning "bolt", "peg", or "nail" and lobos meaning a "capsule" or "pod" referring to "the inflated shape of the seed pods"
Flowers:
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
Fruit:
An oblong to almost spherical legume containing two to many ovules
Leaves:
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

In 2008, Gompholobium grandiflorum was designated the lectotype

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
