Trochomeria macrocarpa is a perennial climbing plant producing annual stems 10 - 30mm in diameter and up to 6 metres long (though generally less) from a perennial fleshy, tuberous rootstock. The stems scramble over the ground or climb into the surrounding vegetation, supporting themselves by means of tendrils[
The root is sometimes harvested from the wild for local use as a food. There are conflicting reports about the edibility of the fruit.
The fruit is non-toxic, but in The Gambia an unstated part of the plant is recognized as poisonous[
Africa - drier areas from Senegal to southern Sudan, south to S. Africa.
Deciduous woodland, bushland and savannah at elevations from 600 - 2,400 metres[
]. Among rocks on granite/quartzite outcrops and wooded ridges, also on flat areas, along river banks and even rarely in disturbed ground[
A plant of the tropics and subtropics, where it can be found at elevations from 600 - 2,500 metres. In S. Africa the plant is found in summer-rainfall areas where the mean annual rainfall can range from 600 - 1,000mm[
Found wild in very sunny to very shady areas[
]. Prefers well-drained or moist, sandy, loamy and/or rocky soils[
A dioecious species, both male and female forms need to be grown if fruit and seed are required[
Root - cooked. The large yam-like root, often deep in the ground, is dug up when mature after the rains; it is boiled or roasted and eaten[
]. Not all the tuber is eaten - the core, for example, is often discarded as being too bitter[
]. The ellipsoid-ovoid tuber can be up to 60cm in diameter and can be buried up to 60cm below ground level[
There is a report that the fruit is eaten, and can keep a person going for the whole day without the need for other food[
]. However, there are also reports that the fruit is not eaten[
]. The fruit can easily be confused with the highly toxic fruit of Adenia digitata[
]. The bright orange-red oval, fleshy fruit are around 20mm long[
The root is sometimes used medicinally[
]. No more information given.
