Maestros y Mariano Bárcenas, 44260 Guadalajara, Jalisco, Mexico; email: [email protected] 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. ebrac- teatum, S. guatemalense, and Villadia patula. Data on the distribution and habitat of each species are given. Keywords: Crassula, Crassulaceae, Echeveria, floristics, Sedum, Veracruz, Villadia. The state of Veracruz, located in the Eastern ous taxonomic treatments or the floristic list for the coast of Mexico, has a great topographical diversity state (Meyrán & López 2003; Pilbeam 2008; Sosa & ranging from sea level to more than 5000 m in alti- Gómez-Pompa 1994) tude which provides vast environmental heterogene- ity and consequently, supports a complex biological TWO NEW SPECIES richness. The total number of angiosperms in the state of Veracruz is estimated to be 6869 spp. (Vi- Echeveria uxorium JIMENO-SEVILLA & llaseñor 2003), surpassed only by Oaxaca and Chi- CHÁZARO sp. nov.
