This plant is closely related to Ceiba boliviana, the chief points of difference being the leaflets in C. Mandoni are more numerous, more membranous, slightly more longly petiolulate, and with strongly marked serrations like the teeth of a saw ; and the main petiole is much longer than the longest of the leaflets, while in our specimens of C. holiviana it is shorter. There is considerable similarity in the calyx of the two species. The position of the staminodial annulus differs ; in C. boliviana it is about the centre of the joined portion of the filaments, while in the present species it is much nearer the apex. Petiole (of C. Mandoni) 4-6 in. long. Leaflets 2^-4 in. long, 1-1^ in. broad at the broadest part, which is about or a little above the centre. Petiolules J-| in. long. Peduncle ^-| in. long.
