Maesopsis eminii or Umbrella Tree , Umushehe , Mutere , Musizi is a kind from the family of the cross thorn plants (Rhamnaceae) and the only member of the genus Maesopsis and the tribe Maesopsideae. It is native to tropical Africa.
description
Maesopsis eminii are unreinforced, large and fast-growing, semi-evergreen trees that grow up to 25-30 meters high or higher (45 meters). The trunk diameter reaches 1–1.8 meters.
The simple and short-stalked, slightly leathery leaves are alternate or almost opposite and are clearly distant round-toothed to entire, with more or less large teeth. The leaves are ovate - lanceolate or elliptical to obovate. They are almost bald, pointed or acuminate to tailed and about 7-14 inches long and 2.5-6 inches wide. The petiole, which is about 1.2 centimeters long, is more or less hairy with rust. The small stipules are sloping.
The five-fold, yellowish-green, small, short-stalked flowers with a double flower envelope are in axillary, stalked and multi-flowered, short, slightly rusty hairy cymes . The flower cup is bell-shaped, the thin disc is fused with the flower cup. Unlike many genera of the family , petals are present, they are 2–3 millimeters long, hood-shaped and enclose the anthers. The small stamens are attached to the petals almost sitting. The ovary is above and single-fan. The short pen is thick, the scar is resistant to fungi and star-shaped and zehnlappig (or five lobes and each two-piece). There is a discus .
The 2–3.5 centimeters large, obovate, bare and slightly pointed fruits with small handle residues are one, rarely two seed bearing, first yellow and later when ripe black-purple drupes . The mesocarp is floury and cream in color.
Distribution and systematics
Maesopsis eminii is found exclusively in tropical Africa. The species and genus were first described by Heinrich Gustav Adolf Engler in 1895 . Within the Buckthorn family is Maesopsis eminii in 1895 by August Weberbauer established tribe filed Maesopsideae, the tribe is monotypic .
Forestry benefits
As a typical forest tree, Maesopsis eminii tends to compete with other trees in terms of length growth, which is why it was recommended as frugal shade for plantations more than a century ago. In addition, its medium-weight and relatively soft, non-durable heartwood is highly valued, at least in the Indian timber market. It is known as Musizi . The umbrella tree is currently experiencing its big comeback as part of projects to reduce carbon dioxide emissions.
