Edible [2]  May be edible. See the Plants For A Future link below for details.
Flower Type [2]  Hermaphrodite
Hazards [2]  The seeds probably contain hydrogen cyanide. This is the ingredient that gives almonds their characteristic flavour. Unless the seed is very bitter it should be perfectly safe in reasonable quantities. In small quantities, hydrogen cyanide has been shown to stimulate respiration and improve digestion, it is also claimed to be of benefit in the treatment of cancer. In excess, however, it can cause respiratory failure and even death.

Usage [2]  This species is capable of growing in exposed conditions in poor soils; It is rather slow-growing, however, and would only be used in situations where faster species were not so suitable; The berries have been rubbed onto the scalp in order to get rid of lice; Wood - moderately light with little strength, it is of no commercial value;
