A new species of Calochortus (Liliaceae) from Oaxaca, Mexico
Background and Aims: The genus Calochortus is a monophyletic group endemic to North America. In Mexico, the Cyclobothra section is the richest and most widely distributed.

| description | Background and Aims: The genus Calochortus is a monophyletic group endemic to North America. In Mexico, the Cyclobothra section is the richest and most widely distributed. During botanical explorations in the Mixtec region of Oaxaca, unknown Calochortus plants were collected, so the objective was to describe these as a new species for science.Methods: The taxon was compared with previously described species; herbarium collections and type specimens were reviewed. The morphological description, an illustration, and a distribution map were elaborated, and its relationships with nearby species were discussed. Its conservation state was evaluated according to the criteria of the NOM-059-SEMARNAT-2010 and the IUCN.Key results: Calochortus multicolor is described, which due to its morphology is situated in the section Cyclobothra subsection Barbati. It is compared to C. barbatus and C. marcellae, from which it differs by its ascending or erect and crateriform to campanulate flowers, green, greenish-yellow, brownish, rose colored or red; petals inside are densely covered with white or yellow hairs and a fimbriated membrane around the distal portion of the gland. The species is endemic to the Mixtec region, Oaxaca and according to the vulnerability criteria it is placed in the Threatened category (A) according to the Official Mexican Standard for Species at Risk and of Least Concern (LC), following the guidelines of the IUCN.Conclusions: Calochortus multicolor is recognized as a new entity for science, which grows on gypsum and calcareous soils, habitat of a large number of regional microendemic plants. It is considered necessary to develop strategies for the conservation of habitats and species in these areas of high floristic diversity. |

Antecedentes y Objetivos: El género Calochortus es un grupo monofilético endémico de Norteamérica. En México, la sección Cyclobothra es la de mayor riqueza y distribución. Durante exploraciones botánicas en la región Mixteca de Oaxaca se colectaron plantas desconocidas de Calochortus, por lo que se planteó como objetivo describirlas como especie nueva para la ciencia.Métodos: El taxón fue comparado con especies previamente descritas; se revisaron colecciones de herbario y ejemplares tipo. Se elaboró la descripción morfológica, una ilustración, un mapa de distribución y se discutió su relación con especies cercanas. El estado de conservación se evaluó de acuerdo con los criterios de la NOM-059-SEMARNAT-2010 y la IUCN.Resultados clave: Se describe Calochortus multicolor que por su morfología se ubica en la sección Cyclobothra subsección Barbati. Se compara con C. barbatus y C. marcellae, de las cuales se diferencia por las flores ascendentes o erectas, crateriformes o algo campanuladas, verdes, verdoso amarillentas, parduzcas, rosadas o rojas; pétalos con la superficie interna densamente pubescente con tricomas blancos o amarillos y una membrana fimbriada alrededor de la porción distal de la glándula. La especie es endémica de la región Mixteca, Oaxaca y de acuerdo con los criterios de vulnerabilidad se ubica en la categoría de Amenazada (A) según la Norma Oficial Mexicana de especies en Riesgo y de Preocupación Menor (LC), según los lineamientos de la IUCN.Conclusiones: Se reconoce a Calochortus multicolor como una entidad nueva para la ciencia, la cual se desarrolla sobre suelos yesosos y cálcicos, hábitat de un gran número de plantas microendémicas regionales. Se considera necesario desarrollar estrategias para la conservación de los hábitats y las especies de estas áreas de alta diversidad florística.
