Abstract: During the ongoing studies of the Crassulaceae family for the Flora of Veracruz (Mexico), we found two new species of Crassulaceae (Echeveria uxorium and Sedum jarocho), and eight new records for the state: Crassula connata var. connata, Echeveria bifida, E. coccinea, E. halbingeri, Sedum corynephyllum, S. ebracteatum, S. guatemalense, and Villadia patula. Data on the distribution and habitat of each species are given.

espanolAntecedentes y Objetivos: Los habitantes de la Meseta Purepecha conservan un excelente conocimiento ancestral sobre plantas medicinales utilizadas para tratar afecciones dermatologicas que no ha sido documentado. Un estudio etnofarmacologico fue realizado en esta region para recopilar informacion sobre el uso de plantas medicinales y preparaciones herbarias utilizadas en la zona para el tratamiento de afecciones dermatologicas, con el objetivo de difundir la medicina tradicional Purepecha e identificar plantas prometedoras en el desarrollo de tratamientos para afecciones cutaneas. Metodos: El estudio se realizo en los 21 municipios que componen la Meseta Purepecha. Se entrevisto a un total de 86 habitantes locales (62 mujeres y 24 hombres). Los datos se analizaron cuantitativamente mediante la determinacion del valor de uso, nivel de fidelidad y el factor de consenso informante. Resultados clave: En total 97 especies de plantas pertenecientes a 47 familias fueron documentadas para el tratamiento de 19 afecciones dermatologicas en la Meseta Purepecha. Asteraceae fue la familia principal entre las plantas colectadas (20.61%), seguida de Lamiaceae (13.40%) y Solanaceae (5.15%). La mayor cantidad de plantas se utilizo para tratamiento de heridas (40.20%), inflamacion de la piel (37.11%) y erupciones cutaneas (37.11%). La principal parte utilizada de la planta fue la aerea (34.75%). Las plantas medicinales con mayores valores de uso fueron Heterotheca inuloides (0.53), Aloe vera (0.37) y Oenothera rosea (0.21). La comparacion de los resultados con la literatura etnomedicinal revelo que 8.25% de las plantas utilizadas en la Meseta Purepecha se registraron por primera vez para tratamiento de afecciones dermatologicas. Conclusiones: Este estudio proporciona nueva informacion sobre plantas medicinales utilizadas en la Meseta Purepecha para tratamiento de enfermedades cutaneas. Se requieren futuras investigaciones farmacologicas y toxicologicas para demostrar la eficacia y seguridad de estas especies para el tratamiento de afecciones dermatologicas. EnglishBackground and Aims: Inhabitants of the Purepecha Plateau preserve an excellent ancestral knowledge on medicinal plants used for dermatological affections, which has not been documented. An ethnopharmacological survey was carried out in this region to gather information on the use of medicinal plants and herbal preparations for treating dermatological affections, to disseminate the Purepecha indigenous knowledge and identifying promising plants for developing new formulations for cutaneous conditions. Methods: The study was conducted in the 21 municipalities that compose the Purepecha Plateau. A total of 86 local inhabitants (62 women and 24 men) were interviewed. The data were quantitatively analyzed through the determination of the use value, fidelity level and informant consensus factor. Key results: A total of 97 plant species belonging to 47 families were documented for treating 19 dermatological conditions on the Purepecha Plateau. Asteraceae was the leading family among the collected medicinal plants (20.61%), followed by Lamiaceae (13.40%) and Solanaceae (5.15%). The largest number of plants was used for the treatment of cuts (40.20%), skin inflammation (37.11%) and rash (37.11%). The aerial parts were the most commonly used (34.75%). The medicinal plant species with larger use values were Heterotheca inuloides (0.53), Aloe vera (0.37) and Oenothera rosea (0.21). The comparison of results with ethnomedicinal literature worldwide revealed that 8.25% of plants used on the Purepecha Plateau were recorded for the first time for the treatment of dermatological affections. Conclusions: This study provides new information on medicinal plants used on the Purepecha Plateau to treat cutaneous diseases. Future pharmacological and toxicological investigations are required to demonstrate the efficacy and safety of these species for treating dermatological affections.

Oxalis morelosii is proposed as a new species, described, and illustrated. It is based on plants from the southern portion of the municipality of Morelia, Michoacan, an area to which this species is microendemic. The new taxon belongs to section Ionoxalis and is similar to O. alpina (Rose) Knuth, O. galeotii Turcz., O. gregaria (Rose) Knuth, O. jacquiniana H.B.K. y O. lunulata Zucc., all of which have 3-foliate leaves and 3-nerved scales on the bulbs. A dichotomous key is provided to help separate the new species from these others.
