The useful trees of northern Nigeria
Lely, Hugh Vandervaes
Plants, Useful -- Nigeria, Northern; Trees -- Nigeria, Northern
=The Flowers= are irregularly shaped, of an uniform red-purple, in
small loose spikes. Two of the sepals are modified and appear to be
petals. There is a concave lower petal with an appendage and two small
petals. There are 8 stamens with peculiar-shaped anthers. The flowers
appear from February to April and are very decorative and highly
perfumed.
=The Fruits= are winged seeds, 2 inches long, the seed portion being
prominently ridge-veined and the wing with close parallel venation.
They become red before drying to pale yellow and are conspicuous.
=Uses.=—The root, which has a rank odour, is made into a concoction
and taken as a purge. Bits of it are also worn as a charm. The seeds
are crushed and used as a substitute for soap and a concoction of them
taken as a cure for colds. The roots are sometimes an ingredient of
arrow poisons. The name “Mother of Medicines” is given it from the
number of medicinal properties possessed by the plant.

=STERCULIA TOMENTOSA= G. & P.—_Kukuki_. STERCULIACEAE.
A common tree which inhabits granite country and may be found in
quantity on hills or in valleys amongst rocks. It does not occur in
the extreme north on laterite formations. There is rarely any length
of bole, the stem branching low down and the large, crooked limbs
spreading wide apart to form a very open crown of irregular form. It
can be distinguished at once by its purple bark. Amongst rocks the
roots are above ground for several feet, clasping the boulders or
creeping between the crevices. Root flanges are common. The branches
are so soft in the wood that they, or even the whole of a fair-sized
tree may be swayed to and fro by the hand, without difficulty.
=The Bark= is purple and quite smooth except for occasional large grey
scales which leave yellow patches of very distinctive appearance. A gum
exudes from the crimson slash and a watery sap flows at certain seasons.
=The Wood= is white and so soft as to be useless.
=The Leaves= are about 4-5 inches long and 3½-4 inches broad, cordate
with the lobes overlapping the stalk, roughly 3-lobed, the middle lobe
being the most prominent and the outline of two other lobes at the base
being sometimes visible. There are 5 main veins corresponding with
these lobes. The leaves are light green and downy on both sides, the
nerves prominent on the under surface. There is a stalk about 3 inches
long. The leaves are soft in texture.
=The Flowers= which spring from old as well as young wood are in small
erect panicles 2-3 inches long, appearing February to April. The calyx
is ½-¾ inches across, pale green with reddish lines from base to near
tip, 5-lobed and downy. There are no petals. The stamens are on a
column which is divided into 5 branches, each bearing 3 anthers. The
anthers surround the style which is curved and finally the stamens drop
off and leave the style exposed.
