Abstract:
Helictotrichon Besser ex Schult. & Schult.f. (excluding
Avenula (Dumort.) Dumort. and Amphibromus Nees)
is a genus of temperate C3 grasses with about 40 species
(Gibbs Russell et al. 1990; Mabberley 2008). The genus
is most diverse in the temperate regions of the northern
hemisphere, especially in Europe, from where it extends
southwards along the African mountains (Afromontane
Region). This paper deals only with those species occurring
in southern Africa, a secondary centre of diversity
for the genus.
