Androcalva gaudichaudii explained

Androcalva gaudichaudii is a species of flowering plant in the family Malvaceae and is endemic to the far west of Western Australia. It is a low, dense shrub that forms suckers and has broadly oval leaves with a heart-shaped base, and clusters of 2 to 11 white flowers.

Description

Androcalva gaudichaudii is a dense shrub that typically grows up to high and wide, and forms suckersr. The leaves are asymmetrical, broadly oval with a heart-shaped base, long and wide on a petiole long with stipules long at the base. The edges of the leaves are irregularly lobed, the upper surface is glossy and sparsely hairy, the lower surface densely covered with mostly star-shaped hairs. The flowers are white, arranged in clusters of 2 to 11 on a peduncle long, each flower on a pedicel long, with bracts long at the base. The flowers are wide with 5 white, petal-like sepals and 5 petals, the ligule much shorter than the sepals. There is a single staminode between each pair of stamens, the central one spatula-shaped and the other two linear. Flowering occurs from July to December and in March, and the fruit is a bristly capsule in diameter.[1]

Taxonomy

This species was first formally described in 1823 by Jaques Étienne Gay who gave it the name Commersonia gaudichaudii in the Mémoires du Muséum d'histoire naturelle, from specimens collected by Charles Gaudichaud-Beaupré.[2] [3] In 2011, Carolyn Wilkins and Barbara Whitlock transferred the species to Androcalva as A. gaudichaudii in Australian Systematic Botany.[4] The specific epithet (gaudichaudii) honours Gaudichaud-Beaupré, a botanist on the Freycinet expedition.[5]

Distribution and habitat

Androcalva gaudichaudii mostly grows as an undershrub in heath between Shark Bay and Yuna in the Carnarvon, Geraldton Sandplains and Yalgoo bioregions of far western Western Australia.

Conservation status

Androcalva gaudichaudii is listed as "not threatened" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions.
