106 F. Pax. — Euphorbiaceae-Acalypheae-Chrozophorinae. 



Nota. Genus bene limitatum est inflorescentiis terminalibus, saepius amplis bracteisque 

 parvis, antherae loculis adnatis, nee pendulis, staminibus numerosis; propius accedit ad Pseuda- 

 grostistaehydem quam ad Agrostistachydem, a priore, quocum staminibus numerosis quadrat, 

 insuper differt glandulis alternipetalis crassis, ab Agrostistachyde ovarii rudimento nullo.
