Acacia equisetifolia
Contents
General Plant Info
Acacia Equisetifolia (Acacia sp. Graveside Gorge), Leaves are narrow and needle like, 10-15 mm long, hairy and arranged in whorls around the stem. The inflorescence is globular and the pods short.
It is very closely related to Acacia hippuroides, including the relatively long phyllodes with minute apical points, non-striate petals, and very small, free, oblong to elliptic sepals, rather similar pods and transverse seeds. The main morphological features separating these two species are the nature of branchlet and peduncle indumentum and various pod attributes.
Acacia Equisetifolia (Acacia sp. Graveside Gorge) is listed as Critically Endangered (Territory Parks and Wildlife Conservation Act 2000 (Northern Territory): 2012)
Geographic distribution
Acacia Equisetifolia , endemic to the Northern Territory, is a newly discovered rare species, known only from the Graveside Gorge area, Kakadu National Park, 220 km east-south-east of Darwin, Northern Territory. It grows on rocky sandstone slopes at cliffline in sandstone woodland.
It has a very restricted distribution, with a total recorded population of less than 1,000 mature individuals distributed quite unequally across two subpopulations about 1 km apart.
Identification
It is a very distinctive perennial with grey-green foliage. Its leaves are narrow and needle-like, 10–15 mm long, hairy and arranged in whorls around the stem. The inflorescence is globular and the pods are short. Fruiting specimens have been collected in March and October. It is apparently an obligate seeder (Kerrigan et al., 2006).
