HAMAMELIDES. 
MYROTHAMNUS FLABELLIFOLIA, Welwitsch. 
Matopo Hills, kopjes, common; also at the Victoria Falls. 
Sept. 309. 
Distrib. Angola, Mozambique District, Rhodesia, Transvaal. 
Grows abundantly in shallow pans on granite. This plant 
shows characteristic drought condition. The leaves fold up and 
are pressed against the stem enclosing the flower catkins, and 
the branches curl over, looking like dead wood. On the first 
shower of rain, the leaves unfold and a plant is often seen one 
half dried up and the other half with green leaves. Soaking in 
water also causes the leaves to unfold.

Another species of this genus was collected at Victoria Falls, 
veld. Fl. and Fr. very young, Sept. 134. It was a small tree 
about 6 m. high, flowers with leaves on young wood. Judging 
from the very young fruit, this plant belongs to Engler and 
Diel’s section Chionanthoides, near C. :a?tense, Engl. The 
flowers are yellow with comparatively large, 5-dentate petals. 
CoMBRETUM sp. 
Victoria Falls, veld, general. Fl. only, Sept. 127. 
A straggling shrub, with long branches, inclined to scramble. 
A lovely sight in flower, as the bare stems are almost covered by 
the dense elongated racemes of white flowers with exserted red 
stamens. This species comes into the section Trichopetale, and
