description

Caulipsolon rapaceum is a recumbent to prostrate geophyte with bulbous roots . The herbaceous internodes are structured and contain additional vascular bundles in their cortex . Their nodes have distinct, fine, horizontal furrows. The almost cylindrical leaves are arranged crosswise and free at their base. The central water-storing cells are hardly pronounced. The bladder cells of the internodes and deciduous leaves are mesomorphic and flattened.

The flowers form little-flowered cymes and are rarely single. They have a diameter of 20 to 30 millimeters. There are five sepals that have grown together to form a short tube. The white petals are free at their base. There are no thread-like staminodes , the nectaries are narrow, shell-shaped.

The five-faceted capsule fruits have bent-back flaps that are fused together in pairs. The capsule fruits contain ocher-colored seeds with a rough seed coat .

The number of chromosomes is 2n = 36.
