Bromuniola gossweileri
HABIT Perennial; caespitose. Rhizomes elongated. Culms erect, or decumbent; 60–120 cm long. Leaf-sheaths glabrous on surface; outer margin hairy. Ligule a ciliolate membrane; 0.5 mm long. Leaf-blades lanceolate; 10–20 cm long; 10–20 mm wide. Leaf-blade venation with distinct cross veins. Leaf-blade surface pilose; sparsely hairy. Leaf-blade apex acuminate.
INFLORESCENCE Inflorescence a panicle.
Panicle open; ovate; effuse. Primary panicle branches spreading.
Spikelets solitary. Fertile spikelets pedicelled. Pedicels filiform; curved; 20–60 mm long; scaberulous.
FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 3–8 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 10–17 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes eventually visible between lemmas; scaberulous.
GLUMES Glumes persistent; similar; shorter than spikelet; similar to fertile lemma in texture. Lower glume ovate; 5–7.5 mm long; 0.8–0.9 length of upper glume; membranous; 1-keeled; 5 -veined. Lower glume primary vein scaberulous. Lower glume apex acute; muticous, or mucronate. Upper glume ovate; 6–8 mm long; 0.9–1 length of adjacent fertile lemma; membranous; 1-keeled; 5 -veined. Upper glume primary vein scaberulous. Upper glume lateral veins with cross-veins. Upper glume apex acute; muticous, or mucronate.
FLORETS Basal sterile florets barren; without significant palea; separately deciduous. Lemma of lower sterile floret similar to fertile lemma; ovate; 9 mm long; membranous; much thinner on margins; 1-keeled; 7 -veined; acute; mucronate. Fertile lemma ovate; 6–9.5 mm long; membranous; much thinner on margins; keeled; 7 -veined. Lemma midvein scaberulous. Lemma apex acute; awned; 1 -awned. Principal lemma awn 2.5–4 mm long overall. Palea oblong; bowed outwards; 0.9 length of lemma; 2 -veined. Palea keels ciliolate. Apical sterile florets resembling fertile though underdeveloped.
FLOWER Lodicules 2; cuneate. Anthers 3; 2–3 mm long. Ovary glabrous.
FRUIT Caryopsis with adherent pericarp.
DISTRIBUTION Africa: west-central tropical, east tropical, and southern tropical.
NOTES Centotheceae. FTEA.
