Roberty subvar. hendersonii (C.E.Hubb.) Roberty (1960) 388, nom. inval.]. — Type: SF 17940 (Henderson) (holo K; SING).
Culms rambling, 70–150 cm long. Ligule c. 1.6 mm long. Blades linear to lanceolate, 10– 22 cm by 6–12 mm, moderately puberulous on both sides. Panicles 8–18 cm long. Racemes 3–10, ascending, 8–17 cm long. Rachis internodes 6–7 mm long. Sessile spikelets upper glume apex acuminate, mucro 0.5–1.5 mm long. Upper lemma awn 11–48 mm long. Upper palea 0.8–1.8 mm long, as long as the lemma. Anthers c. 2 mm long. Pedicels c. 3 mm long.
Distribution — Vietnam, S China (Fujian, Guangdong, Hainan), Taiwan, Malesia: Malay Peninsula (Pahang), N Sumatra (Aceh, E Coast), Sabah.
Habitat — Open, half shaded place, among boulders, on sand, near small stream, moist slope, slopes under Pinus , along path, roadside, 900–2400 m altitude.
Collector’s notes — Creeping to scrambling, erect. Inflorescence very pale green.
Notes — Roberty (1960: 388, 392) erroneously equated Eulalia geniculata Stapf from Africa with Microstegium geniculatum . We presume the combination Pogonatherum aureum forma geniculatum was based on the first.
This species has been illustrated by Hsu (1975) under the name of M. geniculatum and by Chen & Phillips (2007).
