| description | Urtica praetermissa (Urticaceae), a new species from central Mexico, is described and illustrated. It occurs in the trans-Mexican volcanic belt and the Sierra Madre del Sur in the Distrito Federal and the states of Guerrero, Mexico, and Michoacan. It grows at elevations from 2000 to 3100 m in forests of Abies and Quercus-Pinus, as well as scrub derived from these types of vegetation. Two subspecies are proposed: ssp. michoacana and spp. praetermissa. These taxa are separated by characteristics of the stipules: connate in the former and free in the latter. The species appears most similar to U. mexicana but differs in possessing larger achenes and inflorescences that are either completely unisexual or bisexual with the staminate and pistillate flowers intermixed along its entire length. |

Se describe e ilustra Urtica praetermissa (Urticaceae), una nueva especie del centro de México. Se distribuye en el Eje Volcánico Transversal y la Sierra Madre del Sur, en el Distrito Federal y los estados de Guerrero, México y Michoacán. Crece en bosque de Abies, bosque mixto de Quercus-Pinus y matorrales derivados de estos tipos de vegetación en altitudes de 2000 a 3150 m. Contiene dos subespecies: ssp. michoacana y ssp. praetermissa, las cuales se separan por características de las estípulas, connadas en la primera y libres en la segunda. La especie es morfológicamente similar a Urtica mexicana, de la cual se distingue por tener inflorescencias unisexuales o bisexuales con las flores estaminadas y pistiladas mixtas a lo largo de la inflorescencia y aquenios más grandes.
