Jaltomata chihuahuensis (Solanaceae): A New Combination and Observations on Ecology and Ethnobotany

Abstract

The new combination Jaltomata chi huahuensis (Bitter) Mione & Bye is based on Saracha chihuahuensis Bitter.This species is distrib uted in Mexico at the northern end of the Sierra Madre Occidental in the states of Chihuahua, Du rango, and Sonora.Morphological characters, arti ficial hybridizations, and distinct names applied by the Tarahumara, all indicate that J. chihuahuensis is distinct from the more widely distributed but sympatric J. procumbens.Fruits of J. chihuahuensis are consumed raw by the Tarahumara people and are either purple or green at maturity.Chromosome number: n = 12.
