. This species is currently known from three localities, two of which are in close proximity in western Moxico Province. The third locality is over 200 km to the northeast of the Moxico sites, in southern Lunda Sul Province. However, the area of Angola in which it occurs is one of the least well botanised regions of continental Africa (see Discussion) and its range is likely to be larger than currently known given the fact that its preferred habitats are widespread there. Of the two populations found by D. Goyder (pers. comm.), only a single patch of this species was found at the type locality, but at the second locality (his collection 8952) the population was much larger and scattered over several kilometres. The perched valley-grasslands on sand that this species occupies are nutrient-poor and are not suitable for agriculture, so there are no obvious threats. Increased frequency of burning, observed in some areas (D. Goyder, pers. obs.), may result in gradual ecological changes over time but the human population remains low within much of its range at present. It is therefore assessed as of
