5. Species distributed towards tlie 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 hst by HV: 68 or 9 

 p. cent. 



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
