Discussion

Species 3 (1 in the flora).

Nicandra has been considered a close relative of Physalis. The resemblance is superficial; current molecular data neither place this genus with Physalis and its relatives nor indicate a particularly close relationship to any other genus. Although Nicandra comes out near Exodeconus Rafinesque and Solandra Swartz (R. G. Olmstead et al. 2008), it is morphologically distinct; A. T. Hunziker (2001) left it in its own tribe (the Nicandreae Lowe).
