OBSERVATIO.
Si parvi momenti sit preefloratio calycis, hocce Genus cum Moulinsiä nosträ (Erioglosso caulifloro Flor. Senegamb.)
conjungendum. Disco incomplete et quse inde oritur, excentriek staminum pistillique dispositione satis a Cupanüs propriis
distinguitur, etiamsi cum Eis, ut suspicor, conformatlone fructus congruat. Haud procul dubio haec vel illa ex aliis auctorum
Cupanüs, veluti ex. gr. C. canescens Pers. hue referenda. Nomen derivatur ab »/un>(, dimidius, et -fipot, annulus, ob discum
semilunarem.
