The useful trees of northern Nigeria

Plants, Useful -- Nigeria, Northern; Trees -- Nigeria, Northern
=The Flowers=, which appear in December cover the leafless twigs in
pendulous masses. They are lily-shaped, with 5 brownish petals, so
densely covered with silky hairs as to appear white on the tree,
especially when in bud. There are 5 stamens with rolled-up anthers and
a long, white pistil. The attachment of the pistil to the ovary is
peculiar. The concave base of the corolla, which sits on the ovary, is
pierced with a small hole through which the pointed end of the pistil
passes, but when the corolla falls entire, the pistil is prevented from
remaining attached to it by a swelling of the style at the base of the
corolla, on the inside. The ground may be seen littered with the fallen
flowers, each containing the unattached pistil.
=The Fruits= are large, pendulous capsules, 6 inches long, which are
black when ripe and split into 5 sections, releasing a number of small,
black seeds which are embedded in a mass of silky fibre known as Kapok.
The fibre grows from the inner surface of the capsule.
=Uses.=—The wood is used for canoes of inferior quality in places where
a better timber is not handy.
The silk-cotton is used for stuffing all kinds of articles, and by the
native for stuffing donkeys’ saddle-pads. It is also used as a kindling
for flint and steel.

=ERYTHRINA SENEGALENSIS= DC.—_Minjiriya_. _Majiriya_. LEGUMINOSAE.
This species is common locally and prefers the banks of streams, on
which it grows to large dimensions. Examples 40 feet high with a girth
of over 6 feet are met with and numbers may be found growing together
along a considerable length of a stream. It occurs also, more or less
commonly in open forest country, but does not reach the same dimensions
as those near water. The larger trees have 20 feet boles and large,
crooked limbs forming a wide, open crown, irregular in form.
=The Bark= of old trees is very rough and, in the case of those trees
growing on stream banks, covered with lichen. There are long, vertical
fissures and long, heavy scales. The stem of the young tree, and the
branches of the old, are covered with short, sharp thorns with heavy
bases, in pairs, pale brown with black points. The slash is yellow.
=The Leaves= are trifoliate, the lateral pair without stalks, the
terminal larger with an inch stalk. They are a dull, grey-green, often
blotched on the under surface. The leaflets are 2-3 inches long.
=The Flowers= readily identify the species and are borne in bright red,
terminal spikes. Each flower is a highly modified form of the “Pea,”
and consists of a hood-shaped calyx and a large standard petal, folded
down the middle, enclosing the long pistil and 10 stamens, some of
which protrude with the pistil. They appear from November-January.
