Elsewhere in the inter-montane areas, the vegetation is sparse, mainly Fagonia bruguieri, Zygophyllum simplex, Cornulaca monocantha, Citrullus colocynthis, Tephrosia and Indigofera spp. and the grasses Stipagrostis pungens and S. plumosa.
That honour goes to Indigofera astragalina, a member of the legume – or pea and bean – family collected by Daniel du Bois at Fort St George in India in 1700.
The understory vegetation of this elevation includes Indigofera gerardiana, Sambucus ebulus, and Plecanthrus rugosus.
The Namibian portion of the Kaokoveld Desert consists largely of sand dunes sparsely vegetated by isolated plants of Salsola nollothensis, Ectadium virgatum, Merremia multisecta, and Indigofera cunenensis and the grasses Stipagrostis ramulosa and Eragrostis cyperoides.
The next most extensive vegetation types are dwarf shrublands, dominated by Duosperma eremophilum on heavier, wetter sedimentary soils and Indigofera spinosa on stabilized dunes.
There has also been a recent burst of evolution reflected in endemics such as Barleria solitaria, Indigofera cunensis, Merremia multisecta, and Stipagrostis ramulosa.
Important sources were Isatis tinctoria (woad rather than indigo proper), native to northern Europe and Britain; Indigofera tinctorium, imported from India; and Indigofera suffructicosa, imported from the Americas.
Although miombo as a whole has a fairly low degree of generic endemism – sharing many species with the Sudanian and coastal formations – species richness and localized endemism is high in many herbaceous plant genera such as Crotalaria and Indigofera.
The principal shrubby species are Aerva javanica, Indigofera sparteola, Jatropha pelargoniifolia (glandulosa) and Farsetia longisiliqua.
Indigo is made from the Indigofera genus of plants part of the pea family and was plentiful.
