L AFRICA. ger Nigeria: Yola Province; planted in 
cage Dalsiel (coll. 1909), 1 
Boswellia odorata is ae in the native towns of Yola Province, 
Northern Nigeria, where it was collected together with another very 
fine new species, B. bingy Hutchinson, by Dr. J. M. Dalziel, of the 
African Medical Service. The fragrant resin, which is a product of the 
plant, is burnt by the natives to fumigate their clothing, and it is also 
used medicinally. The Hausa name is ‘ Hanu’; the Fufulde name is 
* Andakehi. 
The nearest ally of this species is B. papyrifera, Hochst., which occurs 
in Abyssinia and the Eastern Sudan, and Chevalier has sathered what 
appears to be the same in the Central Chari region.—J. HUTCHINSON.
