Ecology and distribution
Trop. Afr.
Biology : Tufted leafy annual herb 5-35 cm tall; culms 0,5-1 mm Ø, ± triangular; leaf sheaths straw-coloured to brown; blade flat mostly much shorter than culms 1-2 mm wide; inflorescence open, 2-6 cm wide, with 10-40 spikelets, main branches 1-3 cm long; spikelets angular-elongate-ovoid, 3-8x1-1,5 mm; glumes boat-shaped, sharply keeled.
Ecology : Seasonally submerged sandbanks in rivers; seasonal pools in woodland; mud flats; rocky and sandy river-banks; exposed bare alluvial loamy-sandy soil near streamlets and pans; dense Acacia, Commiphora bush with Adansonia; usually a sign of fertile soil; cultivated fields; 0-1500 m alt.
  Hybridisation not uncommon with F. dichotoma (Natal). – “When dealing with older herbarium material anything labelled F. diphylla is what is now called F. dichotoma in recent literature and anything labelled F. dichotoma might well be F. bisumbellata” (Fl. Trop. E. Afr., l.c.)
