Acacia ataxiphylla, commonly known as large-fruited Tammin wattle, [1] is a species of flowering plant in the family Fabaceae and is endemic to the south-west of Western Australia. It is a prostrate shrub with linear phyllodes, spherical to slightly oblong heads of yellow flowers, and curved, narrowly oblong pods up to 20 mm (0.79 in) long.

Description

Acacia ataxiphylla is a prostrate to spreading shrub or subshrub that typically grows to a height of 15–60 cm (5.9–23.6 in). Its phyllodes are linear, continuous with the branchlets but lack wings, sometimes pentagonal in cross-section, straight to curved, 15–60 mm (0.59–2.36 in) long, 1–2 mm (0.039–0.079 in) wide and with a hooked or shallowly turned down tip. There are linear stipules 2–3 mm (0.079–0.118 in) long at the base of the phyllodes. The flowers are borne in a spherical to slightly oblong head 4–6 mm (0.16–0.24 in) diameter in axils on a peduncle 4–12 mm (0.16–0.47 in) long with 15 to 20 yellow flowers in each head. Flowering time varies with subspecies and the pods are narrowly oblong and curved, reddish-brown, up to 20 mm (0.79 in) long and 4 mm (0.16 in) wide. [4] [5] [6] [7]

Taxonomy

Acacia ataxiphylla was first formally described in 1855 by George Bentham in the journal Linnaea: Ein Journal für die Botanik in ihrem ganzen Umfange, oder Beiträge zur Pflanzenkunde from specimens collected by James Drummond. [8] [9] The specific epithet (ataxiphylla) means 'disordered-leaved', probably referring to the "strongly hooked phyllodes, that give plant a somewhat tangled aspect". [10]

In 1999, Bruce Maslin described two subspecies of Acacia ataxiphylla in the journal Nuytsia , and the names are accepted by the Australian Plant Census: [7]

Distribution and habitat

This species of wattle is scattered and infrequent in the Avon Wheatbelt and Jarrah Forest bioregions of south-western of Western Australia. [6] Subspecies ataxiphylla grows in wandoo and jarra woodland within 30 km (19 mi) north and west of Kojonup. [7] subspecies magna in low heath and is apparently restricted to the Tammin area. [7]

Conservation status

Acacia ataxiphylla is listed as "not threatened", [6] but subsp. ataxiphylla is listed as "Priority Three" , [12] meaning that it is poorly known and known from only a few locations but is not under imminent threat, and subsp. magna is listed as "Threatened Flora (Declared Rare Flora — Extant)" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions.
