Figures

Ecology
Seasonally wet habitats, grassland, TerminaliaLannea–Pappea and Brachystegia woodland, crevices in rock faces; near sea level (fide Haines & Lye) –2400(–2700) m
Note
Haines & Lye distinguish var. metralis from var. filamentosa by being taller, 60–100 cm (rather than 20–70 cm). Culms 1–1.5 mm wide (rather than 0.3–0.8 mm) and glabrous (rather than glabrous or scabrid), the characters Chermezon emphasized when he described B. metralis. Hooper keeps both up as species, and says of B. metralis ‘distinguished from B. filamentosa by the dark clearly white-fringed leaf-sheath and the lanceolate glumes.’ Haines & Lye add that most of the East African plants of A. filamentosa could possibly be included in var. metralis. Maquet does not keep up var. metralis, and Gordon-Gray states “ B. metralis ‘from Madagascar’ is now generally accepted as a synonym of B. filamentosa”.
