THE FLORA OF THE GREAT KARASBERG 
from the eastern edge across two-thirds of its breadth. These plains are 
deeply cut by narrow river channels but, only in a few isolated localities, are 
they broken up into ridges and peaks. The main watershed lies between 
the localities 7 and 3, here coinciding with a line which approximately 
bisects the range from south to north. Near the western boundary the 
configuration is very different. Erosion has here been much greater than 
further east and the range is broken up in all directions by deep ravines 
whose sides are frecjuently almost vertical. Among the peaks and ridges, 
which here replace the plateaux of the east, are found the highest elevations 
of the range. These facts are indicated in the above diagram, which 
represents a section, roughly drawn to vertical scale, from Zandmund on 
the east to Wasserfall on the west. 
The names and elevations of the stations visited by the expedition which 
are indicated in the sectional diagram and, by numbers, on the sketch map 
are as follows :

The main watershed between localities 7 and 3 is crossed at 5600 ft. 
The principal localities for which these stations served as centres were as 
follows : 
1. Wasserfall. 
(a) Conglomerate foothills and deep dry ravines (containing water 
pools at the end of January) trending upwards to Scharfenstein. 
(b) An ancient and very broad river bed running west from Wasser- 
fall, now thickly occupied by Euphorbia. 
2. Scharfenstein. 
Eastern slopes from 4800 ft. to summit.
