Abstract
A morphological analysis ofPhysalis and several closely related genera, with emphasis on a group of species known as “atypicalPhysalis,” showed that two of the atypical species are better treated as a distinct genus.Tzeltalia is described and two new combinations are made:T. amphitricha andT. calidaria. Restricted to the highlands of Chiapas, Mexico, and adjacent Guatemala,Tzeltalia is distinguished fromPhysalis by a combination of characters including shrubby habit; fasciculate flowers; lobed corolla; scabrate pollen; and non-invaginated, partially open, coriaceous, and reticulate-veined fruiting calyx.
Resumen
El análisis de un grupo de especies atípicas dePhysalis y otros géneros relacionados demostró que dos especies deben considerarse como otro género. Se describeTzeltalia, un género restringido a los altos de Chiapas, México, y Guatemala y se hacen dos nuevas combinaciones,T. amphitricha yT. calidaria.Tzeltalia se distingue dePhysalis por una combinación de caracteres que incluyen un habito arbustivo, flores fasciculadas, corola lobulada, polen escabroso, cáliz del fruto no invaginado, parcialmente abierto, coriáceo y con venación reticulada.
