Range DescriptionBeta patula is endemic to two islets in the Madeira archipielago, Portugal: IlhÃ©u do Desembarcadouro in the region of Ponta de SÃ£o LourenÃ§o in the eastern part of mainland Madeira, and IlhÃ©u ChÃ£o in the Desertas Islands to the southwest of mainland Madeiraâboth small, uninhabited islets. IlhÃ©u do Desembarcadouro covers an area of 1.8 kmÂ², while IlhÃ©u ChÃ£o covers an area of approximately 0.5 kmÂ². On IlhÃ©u do Desembarcadouro, wild beets show a patchy distribution pattern. B. patula has been recorded at six sites on the islet and shares the habitat with B. vulgaris ssp. maritima and Patellifolia procumbens at five of these sites. On IlhÃ©u ChÃ£o, B. patula is found only at one site where it grows alongside B. vulgaris ssp. maritima and Patellifolia procumbens (Frese and Carvalho in prep.). The extent of occurrence (EOO) is approximately 70 kmÂ² and the area of occupancy (AOO) is less than 10 kmÂ².
