The useful trees of northern Nigeria

=The Fruit= is a plum, single-stoned and fleshy. If cut through before
ripe, the seed can be seen growing in the top under the stigma and it
expands downwards from this point, only partly filling the cavity when
ripe. The ripe fruit is light brown and ribbed, about ½ inch long, and
the stone is white, very hard and marked all over with a raised network.
=Uses.=—The leaves are a valuable fodder for cattle and made into soup
by the natives.

=COMBRETUM ABBREVIATUM= Engl.—_Kariya_. COMBRETACEAE.
This very beautiful species is a climbing or spreading shrub with a
multitude of stems forming a tangled thicket with occasional stems
extending into the air some 30 feet in length. It can be distinguished
by its masses of brilliant red flowers and by the great variety of its
leaves and the pale colour of its fruits. It is not common, so mention
is made of two places where it may be seen, namely, in a “kurmi” at
Rahamma (Zaria Province) and at Dan Tudu, near the G. Mainu Reserve on
the River Rima (Sokoto Province).
=The Leaves= vary very considerably from 3-7 inches long and 2-4 inches
broad. They may be almost as broad as long or twice as long as broad.
On the new shoots there are short branches, modified to the form of
blunt spines at the end of which are single leaves. When these drop off
the thorn hardens but is never very sharp. These leaves are arranged
spirally round the stem, unlike those of the other branches without
thorns, which are inclined to one plane. The leaves are dark green and
smooth and the venation shows up almost white in contrast. The venation
is prominent on the under surface.
=The Flowers= are in enormous panicles several feet in length at the
end of the shoots. The clusters vary in size at close intervals all the
way along the shoot and the flowers themselves all stand up in the same
vertical position, forming a great flat mass of brilliant red bloom.
They appear in February and each consists of a light green 4-lobed
calyx, 4 small red petals meeting at the tips and overlapping. From the
tips of the petals 8 stamens emerge, 4 long, 4 short, bright red, as is
the pistil.
=The Fruits= are 4-winged, ¾-1 inch in diameter, a delicate green when
new and a light brown when ripe. The single seed is long and 4-angled.
They are ripe in March.

=COMBRETUM HYPOPILINUM= Diels.—_Jan Taramniya, Jan Ganyi_. COMBRETACEAE.
A small tree, rarely exceeding 20 feet in height, except in good
soils, found very commonly in the drier country of the extreme north
or in open savannah where the _Terminalia_ species abound. It is not
unlike _C. lecananthum_, but the seeds are larger and the leaf broader.
Its form is typical of the small, wide-spreading trees of the Bush
savannah, one or more stems and a number of spreading branches forming
an open crown. Occasionally, though rarely, the species exceeds 20 feet
and has an 8 feet bole. The tough, deep red fruits are distinctive.
