Augustin Pyramusde Candolle was a Swiss botanist. René Louiche Desfontaines launched de Candolle's botanical career by recommending him at a herbarium. Within a couple of years de Candolle had established a new genus, and he went on to document hundreds of plant families and create a new natural plant classification system. Although de Candolle's main focus was botany, he also contributed to related fields such as phytogeography, agronomy, paleontology, medical botany, and economic botany.

Pomax is a genus of flowering plants in the coffee family, Rubiaceae. Pomax umbellata, found in Australia, is the sole species of the genus. The genus was created in 1830, by the Swiss taxonomist Augustin Pyramus de Candolle, and published in his Prodromus Systematis Naturalis Regni Vegetabilis. Pomax umbellata was first described as Opercularia umbellata by Joseph Gaertner in 1788. but was transferred to the genus, Pomax by Daniel Solander in 1834.

Only found in the south west corner of Western Australia. The preferred habitat is eucalyptus woodland or shrublands. Attractive colourful flowers appear in October and November. This species first appeared in scientific literature in 1839, in the Prodromus Systematis Naturalis Regni Vegetabilis published by the Swiss botanist Augustin Pyramus de Candolle.

Blumea tenella is a flowering plant in the family Asteraceae found in northern Australia from Queensland through the Northern Territory to Western Australia. It is also found in Indonesia, Borneo, New Guinea and New Caledonia.
Leucopogon capitellatus is a species of flowering plant in the heath family Ericaceae and is endemic to the south-west of Western Australia. It is an erect, more or less glabrous shrub that typically grows to a height of 0.2–1 m. It has linear to lance-shaped leaves longer than about 12 mm (0.47 in) long, tapering to a rigid point on the tip. The flowers are borne on short spikes on the ends of branches or in leaf axils on short side branches, with small bracts and bracteoles about half as long as the sepals. The sepals are broad, about 2 mm (0.079 in) long and the petals white and about 4 mm (0.16 in) long, the petal lobes longer than the petal tube.
Styphelia insularis is a species of flowering plant in the heath family Ericaceae and is endemic to the south-west of Western Australia. It is a rigid, scrubby shrub with many branches, linear or oblong leaves and tube-shaped, white flowers.
Styphelia racemulosa is a species of flowering plant in the heath family Ericaceae and is endemic to the south-west of Western Australia. It is an erect, rigid shrub with linear leaves and white, tube-shaped flowers usually arranged in pairs or threes in leaf axils.
Styphelia rigida is a species of flowering plant in the heath family Ericaceae and is endemic to the south of Western Australia. It was first formally described in 1839 by Augustin Pyramus de Candolle who gave it the name Leucopogon rigidus in his Prodromus Systematis Naturalis Regni Vegetabilis from an unpublished description by Allan Cunningham. In 2020, Michael Hislop, Darren Crayn and Caroline Puente-Lelievre transferred the species to Styphelia as S. rigida in Australian Systematic Botany. The specific epithet (rigida) means "hard" or "stiff", probably referring to the branchlets. Styphelia rigida is found in the Esperance Plains bioregion of southern Western Australia and is listed as "not threatened" by the Western Australian Government Department of Biodiversity, Conservation and Attractions.
Leucopogon tenuis is a species of flowering plant in the heath family Ericaceae and is endemic to the southwest of Western Australia. It is an erect shrub with slender, wand-like branches, linear or narrowly lance-shaped leaves and white, tube-shaped flowers arranged in cylindrical spikes on the ends of branches.
