Kigelia - Sausage Tree

Kigelia is a genus of flowering plants in the family Bignoniaceae. The genus comprises only one species, Kigelia africana, which occurs throughout tropical Africa from Eritrea and Chad south to northern South Africa, and west to Senegal and Namibia.

The genus name comes from the Mozambican Bantu name, kigeli-keia, while the common name Sausage Tree refers to the long, sausage-like fruit. Its name in Afrikaans Worsboom also means Sausage Tree, and its Arabic name means "the father of kit bags".

It is a tree growing up to 20 m tall. The bark is grey and smooth at first, peeling on older trees. It can be as thick as 6 mm on a 15-cm branch. The wood is pale brown or yellowish, undifferentiated and not prone to cracking.

The tree is evergreen where rainfall occurs throughout the year, but deciduous where there is a long dry season. The leaves are opposite or in whorls of three, 30–50 cm long, pinnate, with six to ten oval leaflets up to 20 cm long and 6 cm broad; the terminal leaflet can be either present or absent. The flowers (and later the fruit) hang down from branches on long flexible stems (2-6 metres long). Flowers are produced in panicles; they are bell-shaped, orange to reddish or purplish green, and about 10 cm wide. Individual flowers do not hang down but are oriented horizontally. Some birds are attracted to these flowers and the strong stems of each flower make ideal footholds. Their scent is most notable at night indicating their reliance on pollination by bats, which visit them for pollen and nectar.

The fruit is a woody berry from 30–100 cm long and up to 18 cm broad; it weighs between 5–10 kg, and hang down on long, rope-like peduncles. The fruit pulp is fibrous and pulpy, and contains numerous seeds. It is eaten by several species of mammals, including Baboons, Bushpigs, Savannah Elephants, Giraffes, Hippopotami, monkeys, and porcupines. The seeds are dispersed in their dung. The seeds are also eaten by Brown Parrots and Brown-headed Parrots, and the foliage by elephants and Greater Kudu. Introduced specimens in Australian parks are very popular with cockatoos.


Cultivation and uses
In African herbal medicine, the fruit is believed to be a cure for a wide range of ailments, from rheumatism, snakebites, evil spirits, syphilis, and even tornadoes. An alcoholic beverage similar to beer is also made from it. The fresh fruit is poisonous and strongly purgative; fruit are prepared for consumption by drying, roasting or fermentation. In Botswana the timber is used for makoros, yokes and oars. Kigelia is also used in a number of skin care products.

The tree is widely grown as an ornamental tree in tropical regions for its decorative flowers and unusual fruit. Planting sites should be selected carefully, as the falling fruit can cause serious injury to people, and damage vehicles parked under the trees.
