To the botanist the stretches of wooded bush and flat plain offer 
perhaps little that is not to be found in other riverine or landward 
provinces of Central Nigeria, but the absence of Hausa names for 
several trees and plants well known to the local Fulani suggests 
that the collection of plants prepared in this province may contain 
at least a few species not yet known to exist farther west or north, 
As one travels southwards from Bornu towards the Benue an 
obvious difference in the arborescent vegetation of the bush presents 
itself, the preponderance of thorny acacias in the more northerly 
district giving place to broad-leaved trees in increasing degree 
within Yola Province. Gum acacias are still abundant, however, 
and the larger species continue to be conspicuous trees both north 
and south of the river, across the Anglo-German boundary, and 
into Muri Province on the west. 
From a commercial point of view there are at present only two 
vegetable products which are important and valuable enough for 
export, viz., Gum and Shea Kernels (Butyrospermum Parkii, Hausa, . 
“ Kedanya,” Fufulde, “ Karehi”), which after collection by Fulani and 
pagans alike, or bartered from the latter, are brought in considerable 
quantities to the trading companies’ stores. These are, however, 
less a product of native industry than an evidence of their natural 
abundance, and the facility with which they can be procured an 
fetch a market price with a minimum of labour. The Niger 
Company’s store at Yola alone received over 400 tons of butter-nut 
kernels during the months of August and September, 1909, to 
which should be added the quantity which arrives at the German 
firm, while, in addition, the store of the former company at Nafada 
on the Gongola naturally exploits the resources of Yola Provinceé 
as well as of Bauchi and parts of Bornu. 
Gum, which is the predominating forest product of Bornu and of 
time and in the most desultory fashion ree varieties are 
recognised and accepted by the Niger Company under the 
lowing names :—* * Marru “ Mumuye.” 
and 
less “Falli.” Marrua is a district in German Adamawa, and 
Mumuye is the name of a pagan tribe near the Anglo-German
