above given of the Gamo- 
or Epigyne we sometimes 
find polypetalous corollas in Caprifoliaceew and Lobeliucex, and the ovary is 
sometimes superior in Goodeniacew. In the Supere and Dicarpie, poly- 
petalous species are more or less found in HL’ricacew, Monotropacex, Epacri- 
dacexw, Styracex, Oleacex, Primulacex, Myrsinacex, and Plumbaginaceex. 
Again, among the Super and Dicarpie we occasionally find the ovary 
inferior, or partly so, as in Lbenacew, Styracex, Myrsinacex, Primulacex, 
and always in Gesneracew and Vacciniacer. 
In Oleacew and Primulacex, apetalous species sometimes occur ; and 
unisexual species are also occasionally found in Valerianacex, Composite, 
Ebenacex, Myrsinacex, and Plantaginacex, and other exceptions have been 
already noted,
