The inflorescence is shorter than the leaves, branches slender and two-fold. The peduncle is short and slender, standing about him a cover page and several bracts. The flowers are individually. The perianth is uniform and is hexadentate. The gynoecium consists of a Fruchtblattmit a single ovule. There are usually 9 (rarely 6-13 ) stamens.
The fruit is brown, pink, red or black, rarely white. The exocarp is smooth or rough, the mesocarp is thin or somewhat fleshy with fibers in the inner region. The endocarp is membranous. The seed is deeply furrowed, but not bilobed.
The chromosome number is 2n = 36
