Kuntze Moghania semialata (W.T.Aiton) Mukerjee Flemingia macrophylla is a tropical woody leguminous shrub in the family Fabaceae.

Pods are small and turn brown when ripening; they are dehiscent, generally with two shiny black seeds in the vessel.

[1][2] It is a native plant of subhumid to humid (sub-) tropics where average annual rainfall is typically 1100–3500 mm with up to 6 dry months, at altitude up to 2000 m above msl.

Thus its natural habitat is found in Asia including Bhutan, southern China, Cambodia, India, Indonesia, Laos, Myanmar, Malaysia, Nepal, northern Pakistan, Papua New Guinea, Philippines, Sri Lanka, Taiwan, Thailand and Vietnam.

It has been cultivated and naturalised in sub-Saharan Africa (such as Côte d'Ivoire, Ghana, Nigeria, Cameroon), Central and South America (e.g. Costa Rica, Panama, Colombia), and tropical Australia.

[1][3][4] Its natural habitat is often in shaded locations, scrub, woodlands, grasslands, gallery forest edges and alike, and on soils with fertility ranging from very low to intermediate (and even high) acidic contents.

[10] It is also often used to shade young coffee and cocoa plants, for weed suppression and soil enrichment in orchards, and to provide fuel wood and stakes for climbing crop species.

However, it is considered a poor forage since its leaves have a high fibre and condensed tannin concentrations and is not readily eaten by stock.

It is also one of the major sources of the resinous powder, called in Arabic ورس (wars), with variants waras, wurs and wurus, obtained from fruits of the plant.

It is a coarse purple or orange-brown powder, consisting of the glandular hairs rubbed from the dry pods, principally used for dyeing silk to brilliant orange color; the active compound for it is flemingin.
