Description

The plant reaches a height of

The fruits are capsules of 3 to 5 cm in diameter with 4 to 7 points, are green and ripen blackish brown. On ripening, the fruits contain a soft black wet pulp that is messy and inedible, so are normally left to dry on the plant before harvest. By two years of age, often up to a hundred dried fruits can be harvested at a time, giving 400 to 500 seeds a few times a year. Fruit capsules usually consist of four to five lobes, but some may have up to seven. Inside are the seeds, oval, dark-brown, 1.5 to 2 cm in diameter with a mass of 0.45 to 1.00 grams. The cotyledons are open, similar to those of almonds, and covered with a whitish film.
