In Mr. Johnson’s specimen the fruit is obovoid or subglobose, 
about 3 cm, long (not including the 1 cm.-long beak) and somewhat 
constricted at the base, not ventricose as in some varieties. The 
sclerenchymatous endocarp is about 3 mm, thick. The 6-partite 
perianth is accrescent, fleshy and almost encloses the fruit. Its 
segments have a transverse thickening about 5 mm. from their apices. 
According to an analysis made at the Imperial Institute it contains 
“© 69-9 per cent. of oil, equivalent to 14°8 per cent. calculated on the 
whole fruit, or 78:2 per cent. calculated on the dry pulpy covering.” 
The ordinary pulp adhering to the nuts of this form yields 27:2 
per cent. of oil. A specimen collected by Sir John Kirk at Zanzi- 
bar in 1869 shows the perianth enlarged in a similar manner,
