The useful trees of northern Nigeria

=The Bark= is a light brown colour and the scales are small,
rectangular and grey, in patches on the tree. The slash is light red
with a flow of milky sap.
=The Leaves= are 3-4 inches long and some 2 inches wide, of rather
unusual shape, with broad tip, unequal basal lobes and wavy edges
parallel in the middle portion. They are dark green with a bluish,
waxy upper surface, paler beneath, and have ½ inch, stout stalks. The
foliage is dense.
=The Figs= are borne in dense clusters on the trunk and wood of the
larger branches, much branched twigs bearing the heavy crop. They are
pear-shaped, about an inch long, and smooth. They are not edible.

=FICUS GNAPHALOCARPA= A. Rich.—_Baure_. MORACEAE.
A very large fig tree, common throughout the country, but not in dry
localities. It demands a moist site, preferably on the banks of a
stream or in a fairly well watered locality. Though giving a deep
shade it is not, like the “chediya” and “durumi” planted in towns for
that purpose. It occurs in gregarious clumps, self sown and the seed
is distributed by birds or goats and sheep which are very partial to
the figs. It grows to very large dimensions, 50 feet in height with
girths of 10-20 feet. There are two common forms: the high-crowned with
long bole, erect branches and rather narrow, flat-topped crown, and
the heavy-crowned, short-boled tree with low, widely-spreading limbs
and immense crown. This is probably, like many other trees, merely a
question of age and surroundings. Flanges a foot or two high and the
roots running above ground for several feet are common features. The
tree puts on its new foliage very quickly and this is a brilliant dark
green colour.
=The Bark= of young trees is a light green colour with a soft, powdery
covering. That of older trees is very distinctive, grey-green, fairly
smooth with grey scales here and there about the bole and light
brown patches where these have fallen. The trunk presents a mottled
appearance most of the year, and green, grey, light and dark brown and
bluish tints are intermingled. The slash is pale pink with a flow of
milky sap.
=The Leaves= are 4-5 inches long and 3-3½ inches broad, cordate at the
base with irregular margins. They are dark green on both sides with the
veins very clearly visible in lighter colour and all prominent on the
underneath. Both surfaces are rough to the touch, this being the most
distinguishing characteristic of the species. There is a ½-¾ inch stalk.
