that grasses increase in number, proportionally to other natural families, in proceeding from the tropical to the 

 polar regions, though it is on the Savannahs of the warmer temperate zones that they form the most conspicuous 

 traits in the landscape. 



Again, New Zealand, Tasmania, and California must be considered the regions of the Pines, if the number of 

 species in a given area were to determine the point ; but all the Con if era now growing in those three countries, 

 amounting though they do to no less than forty kinds, would not, if planted together, cover the surface that the 

 Scotch Fir does in Europe. The region of the pines is in the latitudes approaching the tropics ; these trees diminish, 

 in number of species and in the proportion they bear to other natural orders, when proceeding northwards from thence, 

 and actually cease immediately beyond that point, where, from the abundance of one species, they appear to be most 

 fully developed. It is interesting to every one to know what vegetable production gives a country the peculiar features 

 of its landscape ; but attractive or wonderful though those features be, they afford no clue to the botanist, who would 

 understand, not what the vegetation of a country appears to be, but what it really is.

In the first Part of this work I described the seeds of the varieties of Montia from these two localities, and 

 expressed my opinion that the genus contains but one species, the seeds of which are variable in size and in the 

 surface of the testa. In the Kerguelen's Land individuals they also vary much in shape.
