occasioiicxlly to both these characters. Thus, we find apetalous genera and 

 species in Banu7iciilacecp, Magnohacece, Berheridacece, Sarraceniacece , 

 Menis^jermacece, Papaveracece, Cruciferce, Canellacece, Bixacece, Vio- 

 lacece, CarijophijUacece, Paronychiacece, Sclerantkacece, MalvacecB, 

 Sterculiacece, and Tiliacece. 



Again, in the orders AnonacecB, Pittosporacece, PohjgaJacecE. Portu- 

 lacacece, Tama/ricacecB, T ernstrcemiacece , Butacecp, and Dipderacecp, we 

 find some monopetalous species and genera. 



In Dilleniacece, Papaveracece, Capparidacecp, BesedacecF, Violacece, 

 Cai-yophyUacece, Portulacacece, Malvacece, and Sterculiacece, some of 

 the species have stamens more or less perigynous instead of hypogjaious. 

 Again, in some orders, as in certain Eaminculacece, Cahjcanthacece, 

 Anonacecp^ Nymphceacecp, Portulacacecp, Cnp^yaridace^, Polygalacecp, 

 Bixacece, Ternstroe7niacece, Vochysiacecp, Tiliarecp, and Dijyferacecp, the 

 calyx is more or less superior.
