Sus especies se caracterizan por presentar un involucro cilíndrico, uniseriado, formado por cinco brácteas que rodean a cinco flores y aquenios cilíndricos a fusiformes; por lo general con un vilano de escamas, escamas y aristas, o coroniforme. Si bien Stevia es un género relativamente fácil de reconocer, la identificación de sus especies suele ser bastante complicada debido a que muchas de ellas no están claramente delimitadas; además, varias hibridan o se reproducen de manera apomíctica. Por lo tanto, como una primera estrategia encaminada a mejorar el conocimiento de Stevia en México, se presenta una sinopsis taxonómica de este género en el estado de Morelos, el cual incluye una quinta parte de las especies mexicanas.  Métodos: Se estudiaron con detalle los ejemplares del Herbario Nacional de México (MEXU) y de algunos otros herbarios nacionales y extranjeros. Con el análisis de los ejemplares se realizaron las descripciones y la clave, y con las etiquetas de recolecta se sintetizaron los datos ecogeográficos de las especies. Las localidades de recolecta se georreferenciaron para elaborar los mapas de distribución.  Resultados clave:  Se presenta una sinopsis del género para Morelos, que incluye una clave para la identificación de las especies, descripciones de cada una de ellas y mapas ilustrando su distribución geográfica en el estado.  Conclusiones:  En el estado de Morelos se registran 25 especies del género, 17 de ellas endémicas de México. Las especies crecen preferentemente en los bosques templados del estado, sobre todo en los bosques de pino-encino y de encino, con unas pocas de ellas tolerando los ambientes tropicales de las partes bajas.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract:  Background and Aims:  The genus Stevia (Eupatorieae) is the third most diverse of the family Asteraceae in Mexico, with 116 species, of which 107 are endemic to the country. Its species are characterized by a cylindrical, uniseriate involucre, consisting of five bracts surrounding five flowers and cylindrical to fusiform achenes, usually with a pappus of scales, scales and awns or coroniform. Even though it is relatively simple to recognize the genus Stevia, the identification of its species is often quite complicated, as many species are not clearly delimitated, and in addition many hybridize or form apomictic populations. Hence, as a first strategy to improve the knowledge of the genus Stevia in Mexico, a taxonomic synopsis of the genus was carried out in the state of Morelos, which includes one fifth of the Mexican species.  Methods: The specimens of the National Herbarium of Mexico (MEXU), as well as specimens from other national and foreign herbaria were studied in detail. Based on examination of the specimens the descriptions and key were prepared, and from the collection labels the ecogeographical data of the species were synthesized. The locations were georeferenced to elaborate the distribution maps.  Key results:  A synopsis of the genus for Morelos is presented, which includes a key for the identification of the species, descriptions of each of them and maps illustrating their geographical distribution in the state.  Conclusions: In the state of Morelos, there are 25 species of the genus, 17 of them endemic to Mexico. The species grow preferentially in the temperate forests of the state, especially in the pine-oak and oak forests, with a few of them tolerating the tropical lowland environments.]]></p></abstract>
