Abstract

Abstract—The genusHechtiaincludes 91 species (with those described herein), 88 of them present in Mexico, and the entire genus is endemic to the region termed Megaméxico 3 by Rzedowski. With 21 species, the Mexican state of Puebla is the second most species rich. As a result of botanical exploration for the project Bromeliaceae of Mexico, we describe here seven new species, all endemic to Puebla:Hechtia anarosae,H.dasylirioides,H.espejoana,H.longissimifolia,H.microcarpa,H.minimiflora, andH.vicesphaeroblasta. The proposed species are compared with morphologically similar taxa (H.caulescens,H.ensifolia,H.flexilifolia,H.fragilis,H.podantha, andH.sphaeroblasta). Morphological descriptions, images, and a map with distributions of the described taxa are included, as well as an identification key and a list of specimens examined of all the species ofHechtiacurrently known from the state of Puebla.Keywords—Balsas Basin, endemism, monocots, Poales.
