Our new genus, Diplocrater, has the small flowers and fasciculate 
axillary inflorescence of Heisteria, but with membranous leaves; the. 
ovary is divided only up to the insertion of the ovules, they, as well as 
the axile placenta, being entirely free from the summit of the cavity, as — 
in Ximenia, Olax, Liriosma, and Schepffia ; and the stamens are equal to 
and opposite the petals, as in Schepffia. The general habit and foliage 
remind one strongly of the figure of Rhaptostylum acuminatum in 
Humboldt and Kunth’s Nova Genera et Species, vol. vii. t. 621, but 
the structure of the flowers is very different, as will appear from the 
following character. 
DIPLOCRATER, gen. nov.—/nvolucrum cupulatum, integerrimum, caly- 
cem mentiens. Calyx cupulatus, integerrimus. Discus petalifer 
calycem intus fere omnino vestiens, calycis margine angustissimo vix 
prominulo. Petala 5, margini disci imposita, æstivatione valvata, 
superne intus incrassata. Stamina 5, petalis opposita, ad basin - 
eorum inserta et intra cavitatem petali quasi recepta, filamento bre- _ 
vissimo crasso, anthera adnata loculis rima brevi dehiscentibus. - 
Ovarium sessile, orbieulare, medio carnoso-pyramidato in stylum 
simplicem abiens, apice ovoideo-stigmatosum. Ovula 2, ex apice - 
placentæ centralis ad summitatem cavitatis non attingentis pendula, 
dissepimento separata ultra ovula non producto.—Species unica 
D. acuminatus. Arbor 15-20-pedalis, ramulis foliaceis elongatis | 
tenuibus, ex omni parte glaber. Folia alterna, exstipulata, breviter - 
petiolata, ovato-oblonga, acuminata, basi rotundata, membranacea, - 
 penninervia, retieulato-venosa, 3~5-pollicaria. Flores minimi, ad — 
axillas foliorum fasciculati, pedicellis semilineam longis. Cupula - 
exterior (e bracteis 2 coalitis formata ?) explanata, fere lineam dia- 
metro, basi carnosula, margine tenui; interior (calyx cum disco 
adnato) paulo longior. Petala triangulari-lanceolata, semilineam -
