Of the forty -five species of Styrax enumerated by DeCandolle, 
I have removed thirty-one into Strigilia, and five into Cyrta ; to 
the remaining nine (some of which yet remain to be verified) 
must be added S. odoratissimum, Champ. (Hook. Kew Jo. Bot. 
iv. 304), S. ellipticum and S. subpaniculatum, Jungh. et Vriese
