The paucity and fragmentary herbarium material limit the species recognition but living material reveals diagnostic characters to delimitate them.  Hypothesis: Hechtia species are circumscribed by a combination of vegetative and floral characters of both sexes. If the new taxon does not share morphological characters with other species, it will be described as new.  Taxon: Hechtia.  Study site and dates: Chamela-Cuixmala Biosphere Reserve, Jalisco, 1985-2023.  Methods:  Field collected, cultivated as well as herbarium material of the new taxon were analyzed and compared to other species from the Pacific Lowlands and adjacent areas, particularly flowers of both sexes, fruits, and seeds. Conservation status using IUCN criteria is reported for the new species.  Results: Specimens of Hechtia chamelensis have been misidentified as H. laevis and H. reticulata (both described from fruiting, fragmentary specimens) but the fruit and seed features of both taxa do not match those of the new species. H. chamelensis is known from the Chamela-Cuixmala Biosphere Reserve and it is characterized by strict sympodial growth pattern, green leaves with red hues, shiny and glabrous above, white lepidote below, panicles usually simple to (rarely staminate ones) 2-divided, staminate flowers pinkish to pale white, pistillate with pale green to white petals.  Conclusions:  Vegetative and reproductive features as well as geographical distribution allow the recognition of H. chamelensis as a new species native from Jalisco, Mexico.]]></p></abstract>

El escaso y fragmentario material de herbario, dificulta la delimitación de especies, pero el material vivo revela caracteres diagnósticos para delimitarlas.  Hipótesis: Especies de Hechtia están circunscritas por una combinación de caracteres vegetativos y florales de ambos sexos. Si un taxón no comparte caracteres morfológicos y vegetativos con otras especies del género será descrito como nuevo.  Taxón: Hechtia.  Sitio y fechas de estudio: Reserva de la Biósfera Chamela-Cuixmala, Jalisco, 1985-2023.  Métodos:  Se analizó material recolectado, cultivado y herborizado del nuevo taxón y se comparó con el de otras especies de las Tierras Bajas del Pacífico y de áreas adyacentes, se analizaron y caracterizaron flores de ambos sexos, frutos y semillas. Se reporta el estado de conservación de la nueva especie utilizando los criterios de la UICN.  Resultados: Ejemplares de Hechtia chamelensis se han identificado erróneamente como H. laevis y H. reticulata (descritas de especímenes con frutos), pero características de frutos y semillas de ambos taxones no coinciden con los del nuevo taxón. H. chamelensis es conocida hasta ahora de la Reserva de la Biósfera Chamela-Cuixmala, se caracteriza por crecimiento simpodial, hojas verdes con tintes rojizos, glabras y brillantes adaxialmente, blanco lepidotas abaxialmente, panículas simples a (raramente las estaminadas) 2 divididas, flores estaminadas con pétalos rosado a blanco pálido, en pistiladas verde pálido a blanco.  Conclusiones: Características vegetativas y reproductivas, y la distribución geográfica, permiten reconocer a H. chamelensis como una nueva especie nativa de Jalisco, México.]]></p></abstract>
