  approximate range

Uapaca kirkiana, the sugar plum or mahobohobo, is a species of dioecious plant in the family Phyllanthaceae. It is native to the southern Afrotropics, where it occurs in well-watered miombo woodlands. Within range it is one of the most popular wild fruits. It is rarely cultivated but trees are left when land is being cleared. Still a traditional food plant in Africa, this little-known fruit has the potential to improve nutrition, boost food security, foster rural development and support sustainable land care. [1]

Contents

In Shona, the fruit are referred to as mazhanje, and in Chichewa masuku.

Range

It occurs in the miombo woodlands of Angola, the DRCongo, Zambia, southern Burundi, Tanzania, Malawi, central and northern Mozambique, and Zimbabwe. [2]

Growth

It is a dioecious species – the clusters of staminate (or male) and single pistillate (or female) flowers are borne on separate trees. It grows to a height of 5–13 meters, and 15–25 cm in trunk diameter. The dark green, glossy leaves are 12–36 cm long and 8–24 cm wide. It is not prone to attack by pests. It grows in areas with over 600mm/year of rain, and prefers well drained sand or gravelly soils low in organic matter; its presence is indicative of poor agricultural soils.

Fruit

Female trees fruit after about 9–10 years from seed. The fruit is roughly spherical drupe about 2–4 cm in diameter, green in colour ripening to yellow or brown. When ripe, the 1.5mm hard shell encloses the yellow flesh which has an appealing sweet taste that has been likened to pear or plum. Fruits usually contain 3 or 4 seeds, though sometimes 5. Fruits weigh between 5 and 50 grams each, with from 0.2 to 30 grams of pulp. The fruit is usually eaten by wild animals such as monkeys.

Propagation

It is usually propagated by seed, which is recalcitrant and germinates readily, reaching 90% after 6 weeks for fresh seed. The tree can also be propagated vegetatively - a success rate of 80% has been achieved with wedge or splice grafts. Air layering is also possible, though these trees have not fared well without a taproot. The tree naturally propagates via underground suckers and forms stands.

Cultivars

Little work has been done developing cultivars, though some named varieties do exist. Since 1996, work on propagating of superior seedlings has been carried out in Malawi, Tanzania, Zambia, Mozambique and Zimbabwe by the Southern Africa Regional Programme.[ citation needed ]

Name

The species is named in honor of Sir John Kirk, explorer and naturalist (1832-1922). [3]

Dovyalis caffra (Warb.), Aberia caffra the Umkokola, Kei apple, Kayaba, Kai apple, or Kau apple, is a small to medium-sized tree, native to southern Africa. Its distribution extends from the Kei River in the south, from which the common name derives, northwards along the eastern side of the continent to Tanzania. The ripe fruits are tasty, reminiscent of a small apple.

<i>Brachystegia spiciformis</i> Species of legume

Brachystegia spiciformis, commonly known as zebrawood, or msasa, is a medium-sized African tree having compound leaves and racemes of small fragrant green flowers. The tree is broad and has a distinctive amber and wine red colour when the young leaves sprout during spring (August–September). It grows in savanna, both open woodland and closed woodland of Southern and Eastern Africa, mostly Tanzania, Zambia, Zimbabwe, Malawi and Mozambique. The word msasa is commonly used as a proper name in African place names. The word also means 'rough plant' in Swahili. Other common names: mundu, myombo, mtondo (Tanzania), muputu (Zambia). The plant is known in the Venda language as mutsiwa, which means 'the one that is left behind'. An outlying population of Brachystegia has recently been discovered in the Soutpansberg mountains of northern South Africa. This tree is a protected species in South Africa.

Miombo

The Miombo woodland is a tropical and subtropical grasslands, savannas, and shrublands biome. It includes four woodland savanna ecoregions characterized by the dominant presence of Brachystegia and Julbernardia species of trees, and has a range of climates ranging from humid to semi-arid, and tropical to subtropical or even temperate. The trees characteristically shed their leaves for a short period in the dry season to reduce water loss, and produce a flush of new leaves just before the onset of the rainy season with rich gold and red colours masking the underlying chlorophyll, reminiscent of temperate autumn colours in the temperate zone.

<i>Ricinodendron</i> Genus of trees

Ricinodendron is a plant genus in the family Euphorbiaceae first described as a genus in 1864. It includes only one known species, Ricinodendron heudelotii, native to tropical Africa from Senegal + Liberia east to Sudan and Tanzania and south to Mozambique and Angola. It produces an economically important oilseed. The tree is known as munguella (Angola), njangsa (Cameroon), bofeko (Zaire), wama (Ghana), okhuen (Nigeria), kishongo (Uganda), akpi, djansang, essang, ezezang and njasang. Two varieties of the tree species are recognized R. heudelotii var. heudelotii in Ghana and R. heudelotii var. africanum in Nigeria and westwards.

Meyers parrot Species of bird

Meyer's parrot, also known as the brown parrot, is a species of parrot native to Africa. A Meyer's parrot has black feathers, turquoise belly, blue rump, and bright yellow markings on the carpal joint of the wings. Most subspecies have some yellow on the top of the head as well. Forshaw (1989) recognizes six subspecies of P. meyeri which vary in home range, size and in markings, including the extent of yellow markings to the head and wings, and the intensity of turquoise markings on the belly and rump.

<i>Pterocarpus angolensis</i> Species of legume

Pterocarpus angolensis is a species of Pterocarpus native to southern Africa, in Angola, Mozambique, Namibia, South Africa, Eswatini, Tanzania, Zaire, Zimbabwe, and Zambia. It is a protected tree in South Africa. The name Kiaat, although Afrikaans, is sometimes used outside South Africa as well.

Grey go-away-bird Species of bird

The grey go-away-bird, also known as grey lourie, grey loerie, or kwêvoël, is a bold and common bird of the southern Afrotropics. They are present in arid to moist, open woodlands and thorn savanna, especially near surface water. They regularly form groups and parties that forage in tree tops, or dust bathe on the ground. Especially when disturbed, they make their presence known by their characteristically loud and nasal "kweh" or "go-way" calls, with the last syllable typically a descending drawl. Within range, their unique combination of appearance and habits precludes confusion with other bird species.
