Distribution

North America.

Discussion

Species 2 (2 in the flora).

Leucophysalis consists of two species: L. grandiflora occurring from Alberta to Quebec and adjacent states in the United States and L. nana occurring in California, Nevada, and Oregon. The northern distribution is unusual among related Solanaceae.

The relationships of the two species and of the genus were more fully discussed by J. E. Averett (2009).
