Nota. Prius indicavi hanc memorabilem plantam propter Ovaria uniovulata ex genere 

 Damasonium excludendam esse, quam opinionem cel. Micheli, qui eam generi Alisina attribuit, 

 adoptavit. Cum autem constructio fructuum in omnibus partibus cum ea reliquarum specierum 



iSQnii congruat, nunc censeo hanc plantam tarnen in genere Damasonium habendam, et 

 hoc genus it;i amplilicandum esse, ut hanc speciem includat.
