THE NIGERIAN TIMBER TREES 863 
and strip off the bark, and use them for rafters in house-building, 
especially in the Benin and Yoruba countries. 
Symphonia globulifera (Kew). Hog Gum. 
It was reported from the Calabar province. 
Allanblackia floribunda. Orogbo erin (Yoruba); Izeni or Iyockan 
(Benin); Atta (Efik); Egba (Ibo, Owerri). 
Distribution.—It is found in the evergreen forests of the 
Jebu Ode, Benin, Owerri(?) and Calabar (?) provinces of 
Nigeria. This tree usually grows on less moist soil and further 
away from water than P. butyraceew, though it likes a moist 
and deep soil. 
Chief Characteristics—The long, hard, brown, enlarged 
sausage-shaped fruit hanging on a stalk shows, when cut, large 
seeds scattered in white pulp, and is thus different in this respect 
to Pentadesma, which has dark-brown seeds embedded in a 
soft, yellowish pulp. The slash is yellow, but only exudes a 
little yellow latex at first. The branches are not so verticillate 
in form as Pentadesma, but are more pendulous, especially 
when the tree is in fruit. They also are further apart 
and give the crown a more open appearance. The fruit is 
three times the length and the diameter rather more than 
that of P. butyracee. 
Timber.—The sapwood is whitish-yellow and the heartwood 
yellowish-red and moderately hard. It is not attacked by 
white ants; it does not split easily, but planes with a smooth 
surface. It is a medium-sized tree, reaching a height of about 
80 feet, with a bole length of 20 feet and a girth of 8 feet. 
Silvicultural Qualities—It is a shade-bearer and grows 
comparatively slowly. Natural reproduction is chiefly by seed, 
though fine and succulent stump shoots appear when a tree 
is cut down. 
The timber has not been exported nor has it been used 
locally ; the natives occasionally cut the bark for medicinal 
purposes, but otherwise apparently have no use for the tree. 
Ochrocarpus Africanus? sp. of Allanblackia. African Mammee 
Apple, Mahogany (Calabar). Igoda (Benin); Ereruku, Edeng 
Edem (Calabar); Baulan Bolo (Degema, New Calabar) ; Okut 
and Otun (Oban, Ekoi). 
Distribution.—It is found in the Calabar, Owerri and Ogoja 
provinces of Nigeria, occurring sparsely in the evergreen 
forests in several localities, where it takes the place of Khaya, 
which is not prevalent in such places. 
Chief Characteristics.—It is a large tree, with orange- 
coloured bark, especially in young specimens, and a little scaly. 
In habit otherwise rather like Mahogany, after which the
