The useful trees of northern Nigeria

Plants, Useful -- Nigeria, Northern; Trees -- Nigeria, Northern
=The Wood= is yellow, hard, crisp under the axe, planes well, seasons
well, is sound and clean and weighs 50 lbs. a cubic foot. In transverse
section the rings are clearly visible as fine white lines, the pores
are minute, open, evenly distributed and more numerous in the light
annual rings. The rays are extremely fine, rather far apart and wavy.
=The Leaves= are about 5 inches long and 2½ inches broad, bright green
and shiny on the upper surface, lighter beneath, with the mid-rib
raised on both sides. The margin is wavy or not, and some leaves are
narrow at the tip and others blunt and flat. They do not form as marked
rosettes as those of _G. ternifolia_.
=The Flowers= are large, white, tubular, 6-petalled blooms, 3 inches
in diameter with a very long, narrow corolla tube from which protrudes
a ribbed club-like stigma, surrounded by 6 stamens consisting only of
long anthers attached by their centres to the corolla. They are very
highly scented and are conspicuous from their size, colour, number and
perfume about December.
=The Fruits= are fleshy, potato-like, yellow, with a smooth surface
and variable in size and shape, though usually long. The flower-parts
are persistent at the top. The firm, juicy flesh surrounds a number of
small, flat, yellow seeds in a bright yellow, pithy pulp, and is sweet
and edible. They are eaten by antelopes.
=Uses.=—The fruits are eaten fresh or made into a sauce as an
ingredient of soup.
The whole plant is cut for fencing farms as protection from goats,
etc., and the twigs are stuck on the tops of compound walls.

=GARDENIA TERNIFOLIA= Thunberg.—_Gauden kura_. RUBIACEAE.
This species, similar to _G. erubescens_, is found in the same
situations, but is less plentiful as a rule. It may be seen mixed with
the other species or over considerable areas by itself. It is, or can
be, a taller species, occurring as a tree about 20 feet high with a
less spreading habit, and a flat-topped crown. It branches from just
above the ground and the branches are crooked and very springy, but not
so stout and blunt as those of _G. erubescens_, in fact, the straight
twigs of this species are very distinctive.
A comparison with _G. erubescens_ shows _G. ternifolia_ to be a larger
or taller tree, less shrub-like; to have greener bark; to have smaller,
darker, rougher and more crinkled leaves with pointed tips, and to have
fibrous, grey-green fruits which vary exceedingly in size and in shape.
=The Bark= is smooth and grey or green with a powdery surface, and
there are small, thin, grey scales which leave greenish-yellow scars.
The end of the twig is covered with knobs of soft green cork. The slash
is yellow, with green edges.
=The Wood= is yellow, close-grained, tough and hard to cut with the axe.
