It appears, from this comparison, that the families are 

 by no means of the same nature in both countries. In 

 Germany, thirteen families occur, wanting in Altai; viz. — 

 the AristolochicB, Verbenacece, JasminecB, LoheliacecB, Cucurbi- 

 tacecB, Loranthece, HederacecE, Tcj'ebinthacece, Acerece^ Cap- 

 paridecE, Tiliacece, Cisfii and Myrtacece. These, together, 

 contain forty-five species, and, therefore, form only l-64th 

 part of the whole German Flora. On the contrary, two 

 families occur in Altai, the FrankeniacecB and Reaumuriacea, 

 which, together, include three species wanting in Germany. 

 Again, those families that are common to both countries, do 

 not contain an equal proportional number of species in both. 

 The Cyperacece amount in Germany to l-22d of the whole 

 Flora, and in Altai to l-32d. The Grasses in Germany, 

 which are almost l-15th, are in Altai l-16th ; the Amentacece 

 l-28th in Germany, and in Altai l-30th ; the Personates in 

 Germany l-29th, in Altai l-26th ; the LabiatcB in Germany 

 l-23d, in Altai l-27th ; the Aroidece, Juncecs, Sarmentacece, 

 Irideae, and Orchidece, form altogether in Germany, 1-2 1st, 

 and in Altai only l-35th part of the whole Flora. Germany, 

 on the contrary, contains only two Polygona more than the 

 Altai. This family amounts there to l-85th, here to l-50th ; 

 and, in respect to the Chenopodia, the German Flora stands 

 so far behind, that this family in Germany only numbers 

 l-67th, but in Altai l-2Tth. Also in Plantaginece, Plum- 

 baginew, and Convolvuli, Germany is poorer than the Altai ;
