Scientific name: Amphibromus whitei

Amphibromus whitei was a perennial "grass-like" plant, often growing in dense clumps or tufts to a height of 30–35 cm. The long, narrow leaves were scattered along the stems. The flat leaf blades, which joined the sheath gradually, were approximately 15 cm long and 1–1.5 mm wide, with a prominent midrib. The leaf margin was smooth. The base of the leaves were densely hairy with golden hairs turned downwards. The ligule (a thin outgrowth at the junction of the leaf and leafstalk) was 4–8 mm long (Weiller et al. 2009).

Amphibromus whitei was recorded from the Maranoa District of Queensland, near Roma, on the edge of a large fresh-water swamp (Weiller et al. 1995).

Amphibromus whitei was a bisexual plant (flowers contained both male and female reproductive parts). The flowerhead usually consisted of 1–3 small closed flowers (spikelets) clustered together. The flowerhead varied from pale green to green in colour. The main axis of the flowerhead was 6–12.5 cm long and the primary branches of the flowerhead were covered in scales (Weiller et al. 2009).

The dry, seed-like fruit of Amphibromus whitei was pale yellow-brown in colour, generally oblong in shape, about 1.3 mm long and 0.4 mm wide (Weiller et al. 2009).

The reasons for the decline and extinction of Amphibromus whitei are unknown.

The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
