 " trived only for two plants," but this is supposing 

 that the whole vegetable world is already known, 

 which is very far from being the case. The same 

 leaves are examples, also, of the two next terms of 

 configuration: the Compressed (compressa), which 

 is used when a thick leaf is flattened laterally, 

 so as to make it thicker than it is broad ; and 

 the flat (plana), when both surfaces of a thick 

 leaf are flat and parallel to each other. A two- 

 edged leaf (folium anceps), JO, displays both the 

 edges, in a transverse section, produced to a very 

 acute angle. The configuration is spherical 

 (sphceroidea) , when it approaches to the globular 

 form : Ovoide (ovoideaj, 1 1 , when it some-
