= Strictly speaking, the genus Cerbera, Linn., is synonymous with Thevetia, and what we now consider 
as Cerbera ought to be named Odollam, Rheede. Linnzeus enumerated three species of Cerbera ; one of them 
(C. Manghas), belongs to the Tournefortian genus Zabernemontana, being identical with T. dichotoma, 
Roxb., as I have ascertained from the authentic specimens of Hermann, preserved at the British Museum ; 
and the two others (C. Ahouai, L., and C. Thevetia), have been referred to Thevetia. _ The species which 
modern authors have placed under Cerbera, are in reality no Cerberas at all, having nothing in common Mes 
the two typical species (C. Ahouai and Thevetia) of the genus. As I am not able at present to ner x all 
the doubtful species now referred to Cerbera, I shall not meddle with the generic nomenclature in this place. 
But I may add that the Tahitian plant considered by Forster and others as C. Manghas is wi very 
distinet new species, which has large white flowers with a yellow centre, erect calyx lobes, -- Ug "p 
leaves. I have named it C. Forsteri, (sp. nov.) Seem. in Herb. Mus. Brit. (C. Manghas, Forst. Prodr. n. 
120, excl. syn., non Linn.; Sol. Prim. FÌ. Ins. Pacif. p. 238; Parkins. Drawings of Tahit. Plants, t. 32 et 33). 
— Nomen vernac. Tahitense, * Reva."— Tahiti (Wiles and Smith!) ; Pitcairn Island, (Cuming! n. 1379). 
Solander has the following description of it under the name of C. Manghas :—“ Arbor 50-pedalis, lactescens.
