Acacia amentifera F.Muell.




Known only from the type specimen.


Shrub(?). Branchlets angled by rather prominent resinous ribs, glabrous. Phyllodes in clusters of 3–5 per node, obliquely oblong-elliptic to oblong-oblanceolate, commonly curved upwards from near base, 6–10 mm long, 1–2.5 mm wide, rostellate to subuncinate, glabrous, lacking discernible nerves but finely longitudinally wrinkled (at least when dry); gland obscure, 1–2 mm above pulvinus. Inflorescences simple; spikes ±sessile, 5–10 mm long, resinous; bracteoles long-acuminate, with claws short, exserted in buds. Flowers 5-merous; sepals free, linear. Pods and seeds not seen.


In the absence of pods A. amentifera seems most closely related to A. conjunctifolia which is most readily distinguished by its normally longer, finely nerved phyllodes (commonly only 1 or 2 nerves evident) and generally longer spikes on peduncles 2–6 (–7) mm long. Perhaps also related to A. phacelia from the NW Kimberley region of W.A.
