LOBELIA MINUTIDENTATA, Engl. 4 Gilg, in Baum, Zambesi- 
Kunene Exp. p. 398. 
Matopo Hills, on edge of bog, where it drains over granite. 
Malam River. Fl. Oct. 272. 
Distrib. Type locality, Chihinde, in Portuguese West Africa. 
This plant was collected by Baum on the Kunene-Zambesi 
Expedition. My specimen is really intermediate between 
L. angolensis, Engl. & Gilg, and L. minutidentata, Engl. & Gilg, 
as it shows the less luxuriant inflorescence and slightly larger 
calix of the former, while in the shape and more obscure 
dentation of the leaves it approaches the latter. The structure 
of the flower is similar in all three, and I am inclined to think 
these are only forms of one species.

Matopo Hills, banks of Malami River, in sand. FI. Sept. 96. 
Distrib. Type locality, left bank of Chitanda River, in Port. 
W. Africa. 
This is an interesting record of another of Baum’s West 
African plants. It is a very characteristic little species, the 
whole plant white with silky adpressed hairs and very minute 
white flowers. Only three specimens of this species were seen 
by me, but it may be more abundant later on in the summer.
