5. Species distributed towards the North and South, but 
not towards the East, denoted in the list by RV: 56 or 7 
p. cent. 
6. Species distributed towards the East and South, but 
not towards the North, denoted in the list by HV: 68 or 9 
pcent, 
7. Species distributed towards the East and North, but 
not towards the South, denoted in the list by HR: 52 or 7 
p. cent. 
8. Species distributed equally towards the East, North 
and South, denoted in the list by HRV: 169 or 22 p. cent. 
From these statistics it follows by addition that 372 
species (48 p. cent.) are distributed towards the East, 306 
species (40 p. cent.) towards the North, 435 species (57 p. 
cent.) towards the South, while 169 species (22 p. cent) are 
endemic. 
These figures form the basis of the following conclusions, 
but their accuracy must only be regarded as more or less 
comparative. As previously stated, the flora of Transcaspia 
is insufficiently investigated, and to a still greater extent is 
this the case with several of the neighbouring countries, 
especially Persia and Afghanistan. This will naturally involve 
mistakes in the figures given above. Another source of error 
is that the species are differently interpreted by the various 
authors who have described the plants of these countries, 
and no descriptive floras have been compiled for the coun- 
tries in question. I have in several cases been obliged to 
decide according to my own judgment. Of course I believe 
that I am right in general, but future investigations on the 
flora of these countries may prove that many species which 
in this memoir are recorded as common to several territories 
ought to be divided into more species, each one endemic to 
its own territory, or that species which are here regarded 
as endemic to Transcaspia are identical with species in other 
countries. 
The figures given above must therefore be treated with 
caution, and conclusions drawn from them can only be 
regarded as rough estimates. 
As endemic species I have reckoned not only those
