Bengalia (Koenig ex Retzio). Vidi specimen a el. Koenig lectum in 
h. Havniensi, Cymbachnes ciliate nomine inscriptum. In herb. Retzii, 
nunc universit. Lundensis desideratur. 
Obs. Retzii descriptio satis obscura et haud sine erroribus. Nam 
quod flores foemineos vocat nihil aliud esse videtur quam pedicelli 
crassi, post delapsas spiculas maseulas relicti.Quæ praterea Retzius 
attulit, ea ita bene cum specimine Keenigii congruunt ut non dubitem, 
quin eandem ac Retzius plantam deseripserim. Synonymon Desvauxii 
minus certum, quia figura supra laudata minus bona; descriptio 
exacte convenit.
