The other species is a tree which I have not observed in the 
Hausa States, and for which I have never been able to ascertain a 
Hausa name. It is called in Fufulde “'Tursuje,” and is a tree of 
about 15 to 20 ft. at most, with pinnate leaves and pendulous 
(W. Afr. Copaiba balsam), along with the odorous resin of two 
re arabi ” 
the whole bark is powdered and burnt. e above mentioned 
species of Boswellia, though well known all over N. Nigeria, are 
exceedingly abundant in Yola Province, and are frequently planted

in native towns, 
These two new species may be described as follows :— 
Boswellia Dalzielii, Hutchinson, sp. nov.; ab omnibus speciebus 
adhuc descriptis foliis glabris argute serratis inflorescentiis elongato-
