Pereskia diaz-romeroana (📷: Martin Lowry CCBYNC4) is endemic to Bolivia. It is drought-deciduous, meaning that it can lose all its leaves during dry periods. In the absence of leaves, the stems can photosynthesize. These leafy #cacti have spines. #Cactaceae #Pereskioideae #Botany #PlantScience 🌾🧪

#Rhodocactus comprises 5 spp from South America. It is a member of the #Pereskioideae, another subfamily of leafy cacti. The two leafy subfamilies are early-divergent lineages in the #Cactaceae; they are a grade, not a clade. 📷: Rhodocactus grandifolius subsp. grandifolius. #Botany #PlantScience 🌾🧪
