Acacia longipedunculata Pedley, Contr. Queensland Herb . 11: 17 (1972)
Shrub to 1 m high. Stems pilose, somewhat viscid. Stipules 1–2 mm long. Phyllodes 15–27 per whorl, terete at base, 10–25 mm long, gently incurved from base, abruptly contracted at apex into mucro c. 1–1.5 mm long, pilose. Peduncles usually exceeding phyllodes, 15–45 mm long, viscid. Heads 25–40-flowered, slightly elongated. Flowers 5-merous; calyx 1.2 mm long, the lobes linear to narrowly triangular, acute or acuminate, 0.4–0.6 mm long, with a few long hairs on back; corolla lobes smooth, sparsely hairy. Pods sessile, linear, curved, 20–40 mm long, 6–8 mm wide, glabrous. Seeds longitudinal, depressed-globular, 4 mm long; pleurogram obscure.
Restricted to shallow sandy and rocky soils, in open forest, near Herberton and in the Paluma Ra., north-eastern Qld.
A distinctive species with long phyllodes and peduncles. For a study of the arrangement and development of the phyllodes of this species see R.Rutishauser & R.Sattler, Canad. J. Bot . 64: 1987–2019 (1986). A collection from 100 km S of Elliott, N.T., P.E.Conrick 1165 (AD, PERTH), resembles this species but has a shorter mucro (0.2–0.3 mm) a pilose non-viscid peduncle, longer bracteoles (3 mm) and pilose corolla lobes. It represents a substantial extension of range, if indeed it is this species.
Acacia porcata appears to be related to A. longipedunculata. Also, the smooth corolla suggests relationships with A. hippuroides .
