DiscosPERMUM. Genus novum. 
Calyx parvus, tubo turbinato brevi cum ovario connato, limbo profunde 
4-lobo, lobis rotundatis. Corolla breviter hypocrateriformis, tudo 
cylindrieo, fauce pubescente, limbi lobis 4 obtusis estivatione imbri- 
catis sub anthesi revolutis tubum equantibus. Stamina 4, fauce 
corollæ inserta, exserta, filamentis brevissimis. Ovarium inferum, bilo- 
culare; ovula in loculis 4-5. Stylus brevis, crassiusculus, ad medium 
bifidus, ramis divaricatis acuminatis. Fructus globosus vel obo- 
vatus, levis, coriaceus, indehiscens, apice calycis limbo coronatus, 
umbilieatus, vel infra apicem calycis basi circulari coronatus. 
Semina in placentis linearibus dissepimento utrinque adnatis inserta, 
compresso-lenticularia, verticalia, septulis membranaceis vel arillis 
lamellatis verticalibus distincta. Embryo in albuminis cartilaginei 
axi rectus, radicula cylindrica infera. Testa fibrosa.— Arbores 
mediocres, ramulis strictis compressis, cortice pallido, foliis oppositis — 
ellipticis coriaceis glabris petiolatis integris in axillis venarum 
primariarum glandulis cavis pilosis preditis, stipulis interpetiolari- 
bus solitariis triangularibus cuspidatis | persistentibus, floribus in 
axillis oppositis sessilibus glomeratis parvis, alabastris gemmisque 
resinosis. Fructus diametro subpollicaris, fætidus. — NECS ss 
This well-marked genus, of which I have been fortunate enough to 
discover two very distinct species, seems to me most nearly allied to 
Pouchetia (Richard). É 
I have to remark that the vertical placentze are at regular distances 
along the face of the dissepiment, the seeds closely packed like books 
on a shelf, and somewhat irregular from pressure, but the shape is that 
of a flat or slightly lenticular dise, or more like a cake, the margins — 
not being attenuated. This structure is the same in both species— - 
which may be named thus:—D. spherocarpum and D. apiocarpum
