Discussion
Species 1.
Until recently, Alkekengi was treated within Physalis; phylogenetic analysis showed that it does not fall within the strongly supported clade of New World Physalis (M. Whitson and P. S. Manos 2005). Alkekengi can be distinguished by its lobed, white corolla and orange-red or bright red fruiting calyx.
