This tree, a relative of the cashew (Anacardium
occidentale 1.), can grow as tall as 18 meters. It
supposedly is or was consumed in South Africa for
its inebriating properties (Lewin 1980 [orig. pub.
1929], 297*). It is possible that marula was the
kanna plant or one of the plants known as kanna
(Schultes and Farnsworth 1982, 174*). The closely
related species Sclerocarya schweinfurthiana Schinz.
has also been characterized as psychoactive (Lewin
1980, 297*; Schultes and Farnsworth 1982, 187*).
Constituents are unknown (Emboden 1979, 191*).
