us.
Information given for each species will give botanical name, known common names, describe the flower, give time of year it
flowered, and where it was photographed, and the areas it occurs in. Names have been matched to Florabase which has also
been used to show distribution.

Gastrolobium spinosum is one of the poison plants that has high levels of Fluoroacetate, synthesized as Sodium Monofluoroacetate
known as 1080 poison. Native animals in the south west have a tolerance to 1080 whereas feral vermin such as cats and foxes
do not, so 1080 bating is used for pest control.

This is the most toxic of all
the poisonous Gastrolobiums, and many plants of the Gastrolobium family are poisonous if eaten by livestock. Orange yellow
pea flowers with red markings, arranged in a circular cluster at the end of each stem. A large shrub with four leaves per leaf
joint. These leaves are wedge shaped, with an indent at the top of each leave, giving the name Heart Leaf. Above right
