Acacia covenyi Tindale

Common Name

Blue Bush




Restricted in N.S.W. to the eastern hills of the Great Divide from the Deua R. to near Kybeyan.


Glabrous shrub or tree 1.5–7.5 m high. Branchlets acutely angled at extremities, pruinose. Phyllodes on raised stem-projections, crowded, slightly inequilateral, narrowly oblong-elliptic, (2–) 3.5–5.5 cm long, 5–11 mm wide, mucronate, thin, glaucous, 1-nerved per face, obscurely penninerved; gland not prominent, 5–25 mm above pulvinus, commonly connected to midrib or pulvinus by fine oblique nerve(s). Inflorescences racemose; raceme axes 3–6 cm long, slender, normally pruinose and flexuose; peduncles 2–5 mm long, slender; heads globular, normally 5–8-flowered, bright yellow; bracteoles sessile, widely ovate, pruinose. Flowers 5-merous; sepals 2/3–5/6-united. Pods narrowly oblong, to 8 cm long, 8–13 mm wide, firmly chartaceous to thinly coriaceous, pruinose. Seeds longitudinal, ovate, 4–4.5 mm long, somewhat shiny, black; funicle straight and appressed to inner surface of pod for 4 mm; aril clavate.


Grows in thickets, mainly on limestone slopes and ridges but also sometimes on quartzite.


N.S.W.: Bendethera Caves, 32 km W of Moruya, E.F.Constable 6857 (NSW); E of Kybeyan near Cooma, early Aug. 1977, G.Neville s.n. (NSW).


Gland morphology is important in distinguishing A. covenyi from related species such as A. prominens, A. barringtonensis, etc., fide M.D.Tindale, Telopea 1: 436, pl. 20 (1980). Acacia barringtonensis is further distinguished by its hairy branchlets, phyllodes, raceme axes, peduncles and ovary.

The distinctive bracteoles are similar to those found in A. dawsonii (sect. Plurinerves).
