Trees. Leaves ovate to lanceolate-oblong, nearly glabrous, with translucent glands. Flowers medium-sized, bisexual or polygamous, terminal or opposite the leaves, often produced on axillary, very reduced branchlets (pseudo-axillary flowers); pedicels articulate at the base, without bracts. Sepals small. Petals im-bricate in bud and finally widely spreading, all of about the same size, oblong-ovate or obovate. Stamens numerous; pollen sacs locellate; connective expanded above the anther into a truncate disk. Ovules numerous, lateral. Monocarps (sometimes very) large, free, stipitate, ellipsoid-cylindric, with large, reniform seeds.
