GENERA DUBIA. 
ANTHELIA, Sehott in Miq. Ann. Mus. Lugd. Bat. i. 127, genus imperfecte descriptum, insularum 
Celebes incola, est ut nobis videtur planta Aaphidophore affinis, sed. stigmate punetiformi, ovario 
imperfecte biloeulari loculis 2-ovulatis, et ovulis funiculis brevibus semianatropis placentis septifixis 
peltatim affixis. 
AmrsAcoxTIS, Schott, Prod, 415, genus ab Englero pretermissum, ad folium tantum in insula 
Radack a. Chamisso detectum conditum, omnino dubium est.
