is sometimes superior in Goodeniacece. In the Superse and Dicarpiae, 

 polypetalous species are sometimes found in EricacecB, Monotroxyacece, 

 EpacridacecE^ Sti/racecB, Oleacece, Priinulacecp, MyrsinacecB, and Plum- 

 haginacece. 



Again, among the Superte and Diearpiai we occasionally find the ovary 

 inferior, or partly so, as in Ehenacece, Styracece, Mi/rsinacece, Primulacece, 

 and always in Gesneracece and VacciniacecE. 



In OJeacecB and Primulacece, apetalous species sometimes occur; and 

 unisexual species are also occasionally found in Valerianacece, Comjwsitce, 

 EbenacecE, Myrsi)iacecE, and Plantaginacece, and other exceptions have 

 been already noted.
