Loudetiopsis baldwinii

HABIT Perennial; caespitose. Culms erect to geniculately ascending; 50–70 cm long. Culm-nodes glabrous, or pubescent. Leaf-sheaths striately veined; scaberulous. Ligule a fringe of hairs. Leaf-blades flat, or involute; 10–13 cm long; 2.5–3.5 mm wide. Leaf-blade apex attenuate.

INFLORESCENCE Inflorescence a panicle.

Panicle open; elliptic, or oblong; 8–13 cm long. Panicle axis bearing deciduous spikelet clusters. Panicle branches abruptly recurved near tip; scaberulous; glabrous.

Spikelets in threes. Fertile spikelets pedicelled; 3 in the cluster. Pedicels fused to each other; united below; filiform; subequal; 0.5–2 mm long; ciliate.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; laterally compressed; compressed slightly; 4–5 mm long; falling entire; deciduous in a cluster with fused pedicels; readily shedding fertile florets; pedicel base hooked. Floret callus 0.2 mm long; pilose; hairy in 2 tufts; obtuse.

GLUMES Glumes similar; exceeding apex of florets; thinner than fertile lemma; gaping. Lower glume lanceolate; 3–3.5 mm long; 0.7–0.9 length of upper glume; chartaceous; dark brown; without keels; 3 -veined. Lower glume surface setose; hairy in lines (along margins); with tubercle-based hairs. Lower glume hairs white. Lower glume apex acuminate. Upper glume lanceolate; 3–4 mm long; chartaceous; dark brown; without keels; 5 -veined (lateral veins close). Upper glume surface setose; hairy on veins (along margins); with tubercle-based hairs. Upper glume apex acuminate.

FLORETS Basal sterile florets male; with palea. Lemma of lower sterile floret similar to upper glume; lanceolate; 3–4 mm long; membranous, or chartaceous; 7 -veined; acute. Palea of lower sterile floret winged on keels; pilose. Fertile lemma elliptic; 2.5–3 mm long; coriaceous; without keel; (7–)9 -veined. Lemma surface pubescent; hairy all along (very sparsely in the middle). Lemma margins involute; interlocking with palea keels. Lemma apex lobed; 2 -fid; with lanceolate lobes; incised 0.2 of lemma length; awned; 1 -awned. Principal lemma awn from a sinus; curved; flat below; 3.5–4 mm long overall; without a column; limb scaberulous. Palea 2 -veined. Palea surface pilose; hairy on back.

FLOWER Lodicules 2; cuneate. Anthers 3; 2–2.5 mm long. Stigmas 2.

DISTRIBUTION Africa: west tropical.
