Type
Type: Ethiopia, Tigray, Mt Semaiata, Schimper 233 (P, holo.; BM, BR!, FT, K!, iso.)
Morphology General Habit
Perennial, up to 105 cm high, spreading by branching scaly stolons.
Morphology Culms
Culms rounded, sometimes somewhat flattened, 16.5–44 cm long, 1–4.5 mm wide, glabrous Culms densely tufted, basal part 4–13 mm wide, covered by old leaf sheaths, the sheaths sometimes fibrous.
Morphology Leaves
Leaves up to 70 cm long. Leaves subtending the primary branches. Leaf blade set off from the stiff sheath by an abscission-plane, marked on the outer surface by a dark band, caducuous, narrowly linear, folded, 29–59 cm long, 3–5.6 mm wide, margins and midrib sometimes scabrid, upper surface sparsely to densely villous, lower surface ± glabrous, apex acuminate Leaf sheath basally reddish-brown, rest brownish-yellow, 3–12.5 cm long; ligule a very dense band of white hairs, 1–2 mm long.
Morphology Leaves Leaf sheaths
Sheath 2.5–14.5 cm long; blade 13–52 cm long, shape and surface as basal leaves
Morphology Reproductive morphology Inflorescences
Spikes spikes pedicellate, in fascicles of 1–6, ovoid, (4–)5–9 mm long, 2–4.5 mm wide. Inflorescence a diffuse panicle with 2–6 main branches protruding from the upper leaf sheaths.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets many per spike, lanceolate, ellipsoid to oblong, 4–5.5 mm long, 1–1.5 mm wide.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes very sparsely hairy, yellowish to pale to dark reddish-brown, elliptic to ovate; all glumes 3–4 mm long, 1–2 mm wide, apex (long) acuminate to mucronate
Morphology Reproductive morphology Flowers
Male flower with 3 stamens. Female flower: sac-like utricle lanceolate, overtopping the glumes, 4–6.2 mm long, 0.4–0.9 mm wide, with a curved beak.
Morphology Reproductive morphology Flowers Androecium Stamens Filaments
Filaments 2.5–3.8 mm long.
Morphology Reproductive morphology Flowers Androecium Stamens Anthers
Anthers 1.1–2.2 mm long
Morphology Reproductive morphology Flowers Gynoecium Stigma
Stigmas often broken off, the basal hairs 2/3 to nearly as long as the nutlet
Morphology Reproductive morphology Fruits
Nutlet linear, 1.3–2 mm long, 0.4 mm wide, glabrous, yellowish-brown.
Ecology
On periodically wet rock surfaces and in mountain grassland; 1350–2600 m
Conservation
Least Concern (LC) due to its wide distribution and fairly common habitat.
Note
" Eriospora abyssinica var. castanea is based on its deeper chesnut coloured glumes in comparison to var. abyssinica, which are, according to Nelmes (1953), fulvous to castaneous to bright reddish. According to C.B. Clarke (1894), Nelmes (1953) and Lye (1983) this variety occurs in the Flora area as well as north of the area. There does not seem to be a clear boundary between glume colour from the Flora area and neighbouring countries, and a lot of intermediate colour forms are found. For this area therefore, var. castanea will not be recognized.
