488 MISS L. 8. GIBBS ON THE 
As is shown in the photograph, the face of the cliff is bare. 
This holds for the whole length of the Falls, except in one or 
two places not so exposed, where small patches of grass have 
obtained a footing. In the Rain Forest, under the trees, there 
are few undershrubs, but the ground is thickly carpeted with 
ereeping plants, the following species being dominant in Sep- 
tember :— Eleocharis capitata, Hemigraphis prunelloides, Cyperus 
Haspan var. B. americana, Scirpus paludicola, Oplismenus sp., 
Achyranthes aspera, Dyschoriste Perrottetii, and the ubiquitous 
Floscopa glomerata; of ferns, Nephrodium molle, Pteris quadri- 
aurita, Cheilanthes farinosa, Nephrolepis exaltata, Adiantum 
Capillus- Veneris, and A. Oatesii were plentiful, with the epi- 
phyte Nephrolepis cordifolia growing round the trunks of trees, 
and Psilotum triquetrum amongst a dense growth of pleurocarpous 
mosses towards the base. Where the Rain Forest ceases, 
beyond the reach of the spray on the east side, we find dense 
masses of young Phænis reclinata, which is only scattered on 
the cataract side, with Phaylopsis longifolia beneath. Vernonia 
senegalensis and tall Andropogons lead on to the usual tree-veld, 
which constitutes the east and major part of the first zigzag, the 
Rain- Forest fringe facing the cataract on the west. 
It should be stated that the species enumerated in the body of 
this paper are only those collected or seen in flower or fruit at 
the most inauspicious season of the year, and as my visit was of 
only two weeks' duration, I speak with the greatest reserve on 
the one or two points which most impressed me.

The Matopo Hills run in a north-eastern direction, about 
30 miles south of Bulawayo, extending over an area about 
30 miles broad and over 100 long. They are not a range of 
hills 1n the ordinary sense of the term, but consist of bosses of 
eruptive granite, which, varyiug in height and in every stage 
of disintegration, form innumerable kopjes massed one against 
the other, wooded to the top with or without intervening strips 
of veld *. The level of the veld varies from 4500 to 5000 feet in 
the north-eastern direction ; the average height of the kopjes is 
from 100 to 150 feet, but tcwards the south they are higher. 
* I am indebted to Mr. Mennell for these altitudes.
