== species numbers == 

 Hi, 
 I do of course agree that it is impossible to say how many species of Euphorbia "God Created". But many of the figures cited for larger genera are wildly out to the number of known species.  
 From the WCSP you get the exact number of species by using the "Build a checklist" option  select family "Euphorbiaceae" and Genus "Euphorbia and click "create a checklist". Under the genus entry for Euphorbia it will say "2003 Species". The WCSP species count is exactly that, not including hybrids or infraspecific taxa, that is why it is so usefull for large genera. 
 By citing the date this search was done, at least you have a referenced peer reviewed source of the number based on actual species counts rather than a guess. I agree the wording should perhaps reflect that this is one count of known species at one particular point in time. However this could be said about any species number. There may be only one species of Ginkgo know today but that does not mean there may be another species as yet undiscovered. 
 And Yes for Psychotria the count is exactly 1900 although I agree that there are at least another 200 or so undescribed species. But I would assume the figure to reflect current knowledge rather than looking in a crystal ball.
