- African Blackwood / Grenadillo - Dalbergia melanoxylon
Other Names: Congowood, Mozambique ebony, Senegal ebony Cape Damson ebony.
Distribution: This African tree has an extensive range on the continent. It can be found in the savanna regions of the Sudan southward to Mozambique, then westward to Angola and northward to Nigeria and Senegal.
The Tree: this small tree is about 30 ft. (9.1 m) maximum height, and a diameter of 8 in. (203mm). Managed Timber Resources LLC has trees of this species that average 50 to 60 ft. (15.2 to 18.3m) tall and with a diameter of 1’-8” (50cm) and up.
The Timber: the heartwood is dark purplish black or brown with black streaks which usually predominate so that the general effect is nearly black. The luster is dull and odor and taste are not distinct. It is very hard and heavy wood with a weight of 82 lb/ft 3 (1,314 kg/m 3 ). The grain is mostly straight with a fine texture. It has a slightly
oily nature. The narrow sapwood is white and very clearly defined.
Seasoning: Blackwood dries very slowly and tends to split, especially in the log. It is advisable to coat the ends to minimize the splitting. Once dried, the timber is slow to absorb moisture.
Durability: The heartwood is said to be very durable.
Working Qualities: This wood has exceptionally good working qualities. It cuts very smooth and evenly, taking an excellent finish directly form the tool of the drill or lathe. It can be tapped for screw threads almost like metal. It is considered to be the best wood available for ornamental turnery.
Uses: A chief use is for woodwind instruments such as flutes, clarinets, bag pipes, etc... It is superior to ebony for this purpose because of its oily nature and resistance to climactic changes. The wood is also used for turnery in making such items as brush backs. Knife handles, chessmen and pool cues.

Spirostachys africana, Family : Euphorbiaceae
South / South East Africa
The wood is hard, heavy, durable and close – grained. The sapwood is creamy white and the heartwood rich brown with a satin – like lustre. It is inclined to be oily and, when freshly worked, has a distinctive sweetish smell. Care should be taken when working with Tamboti – the milky latex from the freshly cut tree is very poisonous and causes extreme irritation to sensitive skin and can damage the eyes. When working care should be taken to keep sawdust out of the eyes. This wood is not suitable for fuel as the smoke will cause headaches and nausea. Africans are warned against this tree from an early age, their fear sometimes almost amounting to taboo which prevents them from damaging any living specimens.
Furniture, turnery, inlay work, cabinet – making and carving.
- Tamboti Description
Deciduous and of medium height, the bark is characterisically rough and black. The milky latex can cause severe irritation to the skin and eyes. Furthermore, it is not used as a cooking fuel because it imparts unpleasant taints to the food. The species enjoys a degree of built-in protection against overuse by humans. Kudu browse it, but hunters are careful when dressing a carcass in Tamboti country not to allow the rumenal contents to spoil the edible cuts. The heartwood is dark brown with darker longitudinal streaks that create beautiful markings.
Figure mottled and banded, sometimes with visible growth increments. It is a hard wood, lustrous and with a powerful, persistent, and pleasant scent sweeter than that of sandalwood. This pleasant odor will last a long time after the wood is cut. A piece of furniture made of it can scent a large room for a long time.
Tamboti flowers in September and the pea sized seeds develop in three-lobed capsules which fall, when mature in November, to the leaf litter below. If you stand by a copse of Tamboti trees on a hot November day you may hear a distinctive rustling in the litter and if you look more closely you will see some flicking in the litter due to some seeds jumping intermittently. Collect some of these jumpers and place them on a plate in the hot sun and the jumping becomes more invigorated. Open one carefully and you will find a small larva whose body suddenly contorts causing the bean to jump.
Used mostly for carving, luxury furniture, turnery and curios. Because of its limited quantities, and the defectiveness of the tree, it is a rare wood and therefore sought for small fancy articles and high grade furniture.
Where they are found
South African Lowveld and Swaziland.
- Tamboti (Spirotachys Africana), commonly called African Sandalwood,The wood has a warm musky fragrance

- Leadwood (Combretum imberbe) (Hardekool)
Common name(s): bastard yellow wood, elephant trunk, ivory tree, leadwood
his semi-deciduous tree normally grows up to 20 metres tall. The Leadwood has always borne the distinction of being the most sought-after firewood. In the Okavango Delta and in the Moremi Game Reserve, this species is abundant and the wood is therefore readily availiable. It burns very slowly with intense heat, and is often used fora fire which is intended to burn all night in order to keep wild animals at bay. The Leadwood tree has a wide-spreading, rather sparse, roundish to slightly umbrella-shaped crown and a single, long, thick, bare stem. The wood is exeptionally hard and very difficult to work but suitable for ornamental workd as well as furniture.
The Hereros and the Ovambos of Namibia regard the Leadwood tree as the great ancestor of all animals and people and they never pass it without paying it the necessary respect.
Recent radio carbon dating, done in South Africa, has established that a Leadwood tree can live up to 1000 years and subsequently remain erect for an additional 50 years.

* Giraffe, elephant, Kudu, grey Duiker and impala feed them on.
* They are thought to live for around 2 000 years and thought to remain standing for at least the same length of time once the tree dies.
* The wood is sometimes used for furniture and the ash of the tree has been used as toothpaste and a white wash for buildings and the gum is edible.
* The Lead Wood is protected specie of tree in Southern Africa.
The semi-deciduous Leadwood tree, Combretum imberbe, is found from KwaZulu-Natal Province of South Africa in the south to Tanzania in the north. It normally grows up to 20 metres (66 feet) tall. The Leadwood tree has a wide-spreading, rather sparse, roundish to slightly umbrella-shaped crown and a single, long, thick, bare stem. Recent radiocarbon dating, done in South Africa, has established that a Leadwood tree can live up to 2000 years and subsequently remain standing for years after the tree has died.
* The wood is very hard, difficult to work with, and termite resistant. It was once used for railway sleepers and is now prized as wood for ornamental work and furniture.
* It burns very slowly with intense heat, and is often used for a fire which is intended to burn all night in order to keep wild animals at bay. It is sometimes used in a barbecue to provide a hot, long-lasting flame.

Acacia erioloba E. Mey., Giraffe thorn. Also known as camel thorn, kameeldoring, mimosa, and Transvaal camelthorn. Another botanical name is Acacia giraffae.
- Camel Thorn Tree - Acacia erioloba
This species is synonymous with Botswana and, like everywhere else in the country, very common in Moremi and the Okavango Delta. The dark, blue-green canopy and the black branches sharply silhouetted against the straw-coloured grass make for yet another of the most striking landscapes to be found in Botswana. The name "Camelthorn" was given by Jacobus Coetse in 1760 some 50 years before Burchell described it. It is a direct translation of the Afrikaans name "Kameeldoring", meaning "Acacia of the Giraffe", and is therefore not at all associated with the camel Giraffes are partial to all acacias and have a specially adapted tongue and lips that appear to be immune to the vicious thorns. The Camelthorn can grow up to 17m high. It is distinguished from other acacias by the blue-green colour of the foliage, the almost black bark and the untidy, pendant, broken branches and twigs. Young twigs are noticeably angled (zigzagged) between pairs of large, white thorns. The most outstanding characteristic, however, are the large ear-shaped pods which are relished by all browsers. It is a deciduous tree which loses its leaves for a short period only. In order to obtain water, the roots penetrate the deep, sandy soil to great depths, which accounts for their green foliage virtually throughout the year. It has been recorded in Namibia that the roots of a particular tree attained a depth of 46 m. In the Kalahari Desert, where the Camelthorn is very common, it has tremendous value as a shadow tree both for humans and animals. It is also one of the first species to get new leaves in late winter, providing valuable fodder at a time which is critical for most browsers.
The bark is very distinctive and very dark-brown to black. Leaves: Compared to other acacias, the leaflets are quite large (7x3mm). Flowers are sweet smelling, bright, golden-yellow balls (1,5cm in diametre).
The fruits are a large (12x6cm), thickened, ear-shaped pod, which is grey in colour with a yellowish tinge.
Thorns are paired and very well developed, strong, white and up to 5,5cm in length.
The Camelthorn is widely spread throughout Botswana wherever deep sand occurs. It is also often a constituent of marginal floodplain woodland.
