G.L.Webster Flueggea fagifolia Pax Phyllanthus amapondensis Sim Margaritaria discoidea is a tree in the family Phyllanthaceae, commonly known as the pheasant-berry, egossa red pear or bushveld peacock-berry.

4 varieties are now recognized (1981), these having in the past been treated variously as distinct species, subspecies or synonymous with typical M.

[5][10][11] Oral administration of an aqueous extract at various concentrations showed no acute toxicity in rats and no adverse change in behavior; suggesting that it may be safe for pharmacological uses.

[6] The aqueous extract of M. discoidea stem bark was investigated for its anti-inflammatory and analgesic activities in animal models (rats): The extract reduced significantly the formation of oedema induced by carrageenan and histamine, and had a good analgesic effect, with the results comparable to those of indomethacin, the reference drug used in the study.

[16] The wood is hard and durable and the trees are fast growing from seed,[4] suggesting that this species may be suitable for agroforestry.

The sap-wood is yellowish, and the heartwood is pinkish-white to brownish-red, hard, heavy, of medium texture, not difficult to work and is suitable for cabinetry; finishing smoothly and taking a fine polish.

[18] When applied on ticks on cattle in the field, the 50% oil extract induced 100% and 50% mortalities in adult R. appendiculatus and A. variegatum, respectively, by 2 days post-application.

[18] The leaves are eaten by the larvae of the scarce forest emperor butterfly (Charaxes etesipe tavetensis).
