SA Tree No: 427
Introduce a finer texture in your garden by planting Atalaya alata.
Atalaya alata is a small to medium-sized deciduous tree, with a sparsely branched crown. The compound leaf has 5 to 7 pairs of leaflets. They are markedly asymmetrical, often almost sickle-shaped. The leaf margins are toothed, particularly along the upper edge.
The flowers are small and white and appear in spring to early summer, September to November. The fruit is three-winged, 1 or 2 of the wings often being partially developed. The fruit ripens in autumn.
The wood is fairly lightweight, brittle, fine-textured and pale yellow-white. This tree resembles Clausina anisata (perdepis), although Atalaya alata leaves do not smell when they are crushed.
Atalaya alata is widely distributed and not declining (Raimondo et al. in prep.).
Distribution and habitat
Atalaya alata is found on rocky slopes of the Lebombo Mountains in northern Kwa-Zulu-Natal, eastern Gauteng, Swaziland and Mozambique. It is sensitive to cold, and it should be grown in warm conditions.
Derivation of name and historical aspects
The specific epithet alata is from a Latin word alatus, meaning winged, and refers to the winged fruit. There are nine species of Atalaya in Australia, Indochina and southern Africa. There are three species in South Africa: A. alata, A. capensis and A. natalensis.
In the wild this tree is browsed by elephant.
In the garden Atalaya alata gives a finer texture in its leaves and bark. It is not known to be of any cultural use other than its suitability for garden use.
Growing Atalaya alata
Atalaya alata is grown from seed. The seeds are collected when the fruit is pale brown and ripe, and before it falls. The seeds are easily cleaned by crushing the seed pod by hand. Treat the seeds with a fungicide to protect them from pre-emergence damping off. Sow seed in summer. Prepare a well-drained, well-aerated soil mix in a seed tray. Spread the seeds in the tray and cover them with a layer of bark or river sand. Water the seed tray with a very fine nozzle, place it in a warm place and always keep it moist. The seeds will take 4-6 weeks to germinate.
