Ancistrachne maidenii (A.A.Ham.) Vickery
Family Poaceae
Ancistrachne maidenii (A.A.Ham.) Vickery APNI*

Description: Scrambling perennial with slender, rigid decumbent stems and ascending branches.

Leaves with sheath sparsely hairy; ligule ciliate; blade subcordate at the base.

Racemes terminal or axillary, c. 4 cm long, the lateral ones shorter and partially enclosed in the sheath. Spikelets falling entire at maturity, 2.5–3 mm long. Lower glume abaxial, a hyaline scale to 0.25 mm long or often reduced or absent. Upper glume distinctly 5-nerved, subequal to the spikelet, obtuse to subacute and, together with the lower lemma, sprinkled with fine, mostly curved, tubercle-based hairs. Lower lemma similar to the upper glume, distinctly 7-nerved, sterile, without a palea. Fertile floret elliptic to lanceolate, obscurely nerved, produced into a short but distinct mucro to 0.25 mm long, the palea subequal to the lemma and similar in texture.
