Acacia burkittii

Acacia burkittii is a species of wattle endemic to Western Australia, South Australia and western New South Wales, where it is found in arid zones,[3] and is a perennial shrub in the family Fabaceae. Common names for it include Burkitt's wattle, fine leaf jam, gunderbluey, pin bush and sandhill wattle.[3] It has also been introduced into India. Previously this species was referred to as Acacia acuminata subsp. burkittii, but is now considered to be a separate species.[4] Grows in mallee, eucalypt and mulga woodland or shrubland, often on sandhills.[5]

Description

Erect or spreading shrub 1–4 m high or sometimes taller; bark finely fissured, dark brown; branchlets terete, glabrous.

Phyllodes straight or curved, terete or subterete, 5–16 cm long, 0.5–1.3 mm wide, obscurely multistriate, usually finely hairy along margins especially towards curved, acute apex; glands absent or 1 inconspicuous gland at base; pulvinus 2–3 mm long.

Inflorescences 2 or 3 in axil of phyllodes; heads ± ovoid or cylindrical, 0.5–1.5 cm long, bright yellow, usually sessile or with peduncles 1–3 mm long. Flowers mostly 4-merous; calyx dissected by 1/2 or more, the lobes usually narrow, with rounded obtuse apices (i.e. ± spathulate).

Pods slightly curved, moniliform, 5–12 cm long, 5–7 mm wide, papery, glabrous; seeds longitudinal; funicle expanded towards seed.

Flowers from July to October.

Taxonomy

The description (by Ferdinand von Mueller) was published in George Bentham's Flora Australiensis in 1864 from a specimen, MEL 2078154,[6] found near Lake Gilles in South Australia, by Burkitt.[2]

Alkaloids

DMT in bark (0.2-1.2%), 0.1% alkaloids from leaves (mostly NMT);[7] 1.5% alkaloids from leaves and stems, mostly tryptamine[8]
