The useful trees of northern Nigeria

=The Flowers= are pendulous balls some 2½ inches in diameter on a 7
inch stalk. They appear in March before the new leaves or with them
and are dark red in colour and sweet-scented. They consist of 10 long,
red stamens with black anthers and a simple style, in a 5-lobed calyx
with honey glands. The flowers are visited both by bees and flies.
Called “tutu” by the native, boys suck the balls for the honey. The
flower-buds are called “gundar tutu.”
=The Fruit= is a bean, some 9 inches long, dark brown in colour, in
pendulous clusters on the tree in July. When young they are called
“sabada”; when brown, but before ripening, they are called “garda.” The
ripe seeds are black and embedded in a yellow, mealy pulp. They are of
great value as an annual food-crop.
=Uses.=—The timber is used for making mortars and basins. The seeds are
fermented and made into cakes called “daudawa.”
The husks are soaked in water till fermentation takes place and the
resulting liquid spread over earth floors and on the walls of dye-pits
to bind the surface. The liquid is called “makuba” and is also used as
a fish poison.
The branches are cut for fuel for the boiling of the water used in the
purification of women after child-birth.
The mealy pulp round the seeds (garin dorowa) is used in soup.
An infusion of the bark is a tonic.

=PARKINSONIA ACULEATA= Linn.—_Sasabani, Sharan labbi_. “_Jerusalem
Thorn_.” LEGUMINOSAE.
A small exotic tree introduced by Arabs and planted in most of the
Northern towns to such an extent that it is worthy of inclusion here.
It is a delicate and graceful shrub-like tree up to 25 feet high. It
has a single stem branched a foot or two above ground level; in some
cases there is a stem over 6 feet in length before the branches, erect,
with their ends spreading out and drooping down, occur. It grows best
in an open position and does not thrive in the shade, where it grows
very weak and straggling, without the vivid green of trees in the open.
=The Bark= is bright green and smooth.
=The Thorns= are straight and sharp, ¼ inch long, light red in colour
with thickened, fleshy green bases from which spring the leaves. The
scars of fallen leaves can be seen on this thickened base.
=The Leaves= are bipinnate with one or two pairs of pinnae which
consist of a broad, flat mid-rib some 9 inches long from which little
oval leaflets under ¼ inch long spring alternately. These are sensitive
and at night, or when gathered, fold inwards and lie flat on the
mid-rib. The rib and leaflets are dark green and smooth.
=The Flowers= are in pendulous, sparse spikes amongst the leaves. Each
is an inch in diameter and has 5 pale green sepals, 5 crinkly yellow
petals, one of which is more prominent than the rest and forms a throat
covered with small red spots. There are 10 short stamens with red
anthers and a short brown pistil. The flowers are found most months of
the year.
