The intervening distance varies according to the localities, 
— it is less in more horizontal, damper places, which there- 
fore at a distance assume a strange dotted appearance, — 
greater on parched southern slopes, which seem at first 
glance to be entirely bare. 
On the whole the vegetation of High Pamir lends only 
a faint greenish hue to the landscape. Seen from a high 
altitude, brown seems the colour of the entire country; the 
mountains are brown, brown too the flat bottoms of the 
broad valleys, while the talus look like darker brown sha- 
dows at the base of the mountains. At the bottom of the 
furrows on the mountain-sides dark green lines may often 
be seen; they are narrow stripes of vegetation which only 
serve to make the furrows appear even deeper, accentuating 
the picture just as an exaggerated retouch may a photo- 
graph. Looking toward the north and east nothing green 
or only the very faintest green tones are visible, because 
from that point only the slopes with.a southern or south- 
western exposure are turned toward the spectator, but look- 
ing toward the south a greenish shadow seems to rest on 
those mountain-sides having no western exposure. Exposure, 
as the following will also prove, plays then a very great 
part for the vegetation of High Pamir. 
I have previously (PAULSEN, 1912) given an account of 
the biological types (growth-forms, based on RAUNKIAER'S!) 
system), to be found in Pamir. The following statistics give 
a summary of the facts.
