TREES OF THE YEAR 2006

Common Tree: Wild Pomegranate

National Tree Number: 688
Botanical name: Burchellia bubalina
Other names: Wildegranaat, isiGolwane, umFincane

Description:
Shrub or small evergreen tree 3 to 5m in height but occasionally reaching 10m.

The Wild pomegranate is widely propagated as ornamental garden tree for it is attractive at all times and beautiful when in flower. Although slow growing, it is easily propagated from seed or cuttings. The showy flowers of the tree (which appear from September to December) contain copious amounts of nectar, and are pollinated by birds. The genus Burchellia was named after the traveller and botanist, William Burchell.

The bark is grey, mottled, smooth. The leaves are broadly ovate, 50-180 x 25-80 mm, glossy dark green. The flowers are orange to dark red in colour, tubular in shape and occurring in dense terminal clusters. The fruit is urn-shaped, rather leathery, about 1 to 1.5cm long, reddish-green to brownish, crowned with persistent horn-like enlarged calyx lobes. The wood is hard, dense and closed-grained.

 
 
 
Uses:
The roots provide an infusion which is taken as an emetic and used as a body-wash. The wood is used for hut-building and the making of agricultural implements. The wild pomegranate has become increasingly popular as a small ornamental garden tree.

Distribution:
It occurs in the high rainfall areas of the eastern parts of the country, mainly in evergreen lowland to montane forest and at the margins of forest, but occasionally also in woodland, grassland in rocky outcrops and also in swamp areas.


Rare Tree: Kosi Palm

National Tree Number: 26
Botanical name: Raphia australis
Other names: Kosipalm, Umvuma

Description:
A massive palm up to 24m high, erect stem, not suckering, usually with breathing roots growing up from the soil below the tree. It flowers once after about 30 years, sets fruit and then dies.

A magistrate at Mtunzini planted a grove of Kosi palms just after the turn of the century, and later their spread in this area was encouraged by an offi cial employed in malarial control who, in the course of his work, planted seeds wherever he thought the conditions suitable for the plants, and they all germinated and prospered.

The bark is thick and overlapping scales. The leaves are pinnate and feathershaped, very large, up to 10m long, spreading, dark green to bluish green, leaflets with margin and midrib spiny.

The flowers are in a massive, up to 3m high, conical, apical inflorescence above the crown of leaves. The fruit is oval, about 90mm long, shiny brown. The inner trunk does not consist of solid wood, but is fibrous in texture.

 
 
 
Uses:
The leaves of the Kosi palm are used as a thatch material, and the petioles for hut construction, outriggers for canoes, fences and rafts. The trees are vital for the survival of the rare Palm Nut Vulture.

Distribution:
The Kosi palms occur naturally in the north-eastern extremity of Kwazulu Natal and in southern Mozambique, where they are usually found in swamp forest, often in dense groves. As the name indicates, the palms are mostly found in the vicinity of Kosi Bay, but some trees became naturalised further south up to the Mtunzini area. Palm nut vultures (Gypohierax angolensis) nest in the trees and feed on the fruit.
