boundary, larger in the mixed deciduous forests farther south and in 
fringing evergreen belts. The foliage is dark and the bark blackish ; 
the inconspicuous whitish flowers, of separate sexes on different trees, 
are attractive to bees. The wood is white, with a black heartwood, 
and the spherical yellow fruits (“‘ Monkey Guava’) have a crisp rind 
and sweet edible pulp, with four or five seeds. 
Strychnos spinosa, Lam. (Loganiacee). Kokiya. 
A small thorny tree with opposite three- to five-nerved leaves, 
conspicuous by its round yellow fruit, which is orange-like, but has a 
hard rind and flat seeds embedded in a pleasant acid edible pulp. 
Cordia Abyssinica, R. Br. (Boraginezx). Aliliba. 
A shrub or small tree with broad leaves and white flowers, valued 
for the sweet yellow berries, which are used in making sweetmeats. 
Kigelia Aithiopica, Decne.; var. Bornuensis, Sprague (Bignoniacez). 
Rahaina or Rawuya. 
A species of ‘“‘ Sausage Tree,” of irregular distribution in Northern 
Nigeria, known in Sokoto, etc., but commoner in the Benué region 
and in Bornu (possibly more than one species occurring). It grows to 
a fairly large size, with dense foliage and pendulous racemes of lurid 
purple and spotted flowers and large, yam-like fruits. 
Stereospermum Kunthianum, Cham. Jiri or Sansami. 
A small tree of the savannah forests, with smooth pale bark, 
beautiful pink caducous blossoms and long slender pods. 
Vitex Cienkowskit, Kotschii et Peyr. (Verbenacex). Dinya. 
A fairly large tree, chiefly of open forest country and extending 
at least as far as the Anglo-French border. The bark is somewhat 
smooth, the crown of digitate leaves fairly dense, and the black, damson- 
like fruits are used in making molasses and sweetmeats. The natives 
value the wood as strong and suitable for local use. 
Uapaca Guineensis, Muell. Arg. (Euphorbiacez). Ka Jafogo. i: 
In the open country a rather small tree, with the habit of a Ficus, 
but becoming a large tree, sometimes prop-rooted, in the Benué region 
and in some ravines. 
Chlorophora excelsa, Benth. and Hook. (Moracee). The “ Iroko ” 
or “ Odum.” 
Some of the splendid Nupé canoes are made of this, but the tree 
really belongs to the southern forests, though it occurs in the Benué 
region and perhaps in some northward extensions in river valleys.
