Morphology General Habit
Robust perennial tussock plant 15–50 cm tall with short woody rhizome.
Morphology Stem
Stem 0.4–0.8 mm thick, angular or ± flattened, scabrid or shortly hairy
Morphology Leaves
Leaves basal.
Morphology Leaves Leaf sheaths
Sheaths pale reddish brown, glabrous or shortly hairy but with long hairs at the throat; blades up to 10 cm long, 0.3–0.5 mm wide, shortly hairy or scabrid
Morphology Reproductive morphology Inflorescences
Inflorescence a dense head or lax, 1–3 cm wide, of 1 sessile and 2–5 stalked spikelets and sometimes 1–2 additional spikelets at base of the stalked ones.
Morphology Reproductive morphology Inflorescences Peduncles
Peducles 0.5–1.5 cm long.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets 5–8(–12) × 2–3 mm.
Morphology Reproductive morphology Inflorescences Bracts
Bracts reddish brown, triangular but with long excurrent green midrib.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes ferruginous to dark reddish brown with paler margins, ovate-oblong to elliptic-oblong, 3.5–4.5 mm long, minutely hairy
Morphology Reproductive morphology Fruits
Nutlets olive-brown to pale reddish brown, oblong-obovoid, 1–1.4 mm long (excluding style base), 0.8–1 mm wide, 3-angled, with 8–12 prominent rounded wrinkles on each face and close microscopic ribbing.
Morphology Reproductive morphology Flowers Gynoecium Style
Style base 0.2–0.4 mm long, persistent.
Ecology
Rocky hillsides; ± 1650 m
Note
Gordon-Gray says extremely common in Natal, polymorphic and taxonomically difficult. Lye does not mention any inflorescence but open lax ones, but Gordon-Gray dealing with variation mentions plants with single hemispherical heads of closely packed sessile spikelets. I am not sure that B. boeckeleriana should be kept distinct from B. contexta and the specimen is not really different from B. boeckeleriana var. transiens. Haines & Lye state of B. contexta ‘only from Tanzania’ and do not state from which specimen the drawing is taken.
