The umbilicals have at least three husk leaves that are formed on all sides. Sepals are mostly indistinct. The round, about half a millimeter long petals are white and bare. The fruit is more or less ribbed and around twice as long as it is wide.

Chromosome number

The number of chromosomes is 2n = 20.
