The following exceptions may be noted to the characters usually distine- 
tive of the Disciflore. Thus we have apetalous species in Zygophyllacex, 
Geraniacex, Bilsaminacex, Rutaceew, Simarubacex, Burseracex, Olacacezx, 
Celastracew, Rhamnacex, Sapind weex, Anacurdiacee, and some others. 
Gamopetalous corollas are foundin Humiriacee, Rutacex, Balsuminaceer, 
Meliacexe, and Stackhous'acex. 
Again, in Geraniicex, Balsaminacex, Tropwolacex, Oxalidacexw, Acer- 
acew, Anacardiacer, Malpighiacex, Linacee, &c., the disk is small, or entirely, 
or partially absent. ‘The ovary is more or less inferior in some Olacacex 
and Rhamnacex ; and the placentation is parietal instead of axile in some 
Ochnacee and in Moringaceex.
