Morphology

This plant is an erect, woody undershrub reaching up to one meter in height. The stems are covered with fine, branching hairs. The leaves are obovate to elliptic, displaying characteristic obtuse or rounded apices.

Small, pale green flowers occur in compact axillary clusters. The resulting fruit is a small, orange-red globose berry hidden inside a larger, inflated calyx.

Interesting facts

  • The name obtusifolia refers to the blunt or rounded leaf tips that distinguish this subspecies.
  • Its persistent, papery calyx acts like a protective bladder around the developing berry.
  • The plant contains secondary metabolites called withanolides, which serve as natural deterrents against herbivores.
