same species on the Mau at a similar altitude. German East Africa ; 
Usambara, Kwai, 1700 m., Fick. 
The above description has been drawn up exclusively from Battis- 
combe’s specimen, which has also served as the type of the plate. 
Kick’s Usambara specimen* has smaller, less coriaceous leaves with 
shown in the raceme next to fig. 5 of the plate, is that the lowermost 
one or two bracts are foliaceous, rather smaller than the leaves and 
with more pronounced nervation, but otherwise similar, possessing 
distinct vagina and adnate stipules. The lamina is sometimes 
considerably reduced, in one case practically to the midrib, so that 
it becomes subulate, but the vagina and stipules are hardly altered. 
The upper bracts are triangular, acuminate, under 0-5 cm. in length, 
and have neither vagina nor stipules. 
Only two species of Berberis are known from Tropical Africa, and 
one from Arabia. B. Petitiana, C. K. Schneider,t from Abyssinia, 
possesses the same foliaceous bracts as B. Holstii, and may have to 
be united with it when better known. B. Forskaliana, C. K. Schneider, 
a native of Yemen, appears to be specifically distinct, but its flowers 
are not yet known. 
The genus Berberis apparently originated in the Northern Hemisphere, 
and has penetrated southwards in America, Africa and Asia as far as 
Tierra del Fuego, Usambara and the Malay Archipelago respectively. 
. SPRAGUE. 
Fia. 1, base of a foliaceous bract, showing the articulation of the lamina with 
the vagina: the blunt appearance of the stipules is due to the upper subulate 
part having been broken off ; 2, flower; 3, the same, expanded; 4, petal and

* It has not been possible to ine the type, which was collected in Usambara 
by Holst, but Eick’s specimen has been identified as B. Holstii in the Berlin 
Herbarium.
