Species of the range in size from herbaceous plants to shrubs that measure up 4 m height. Most members have leaves fleshy fully succulent live very diverse habitats ranging shady understory exposed full sunlight. utilize different photosynthetic pathways C3 C4 Crassulacean acid metabolism (CAM) CAM‐cycling plants. We are interested prevalence CAM pathway this family. studied nocturnal CO2 uptake, diurnal fluctuation, phosphoenolpyruvate (PEP) carboxylase activity Portulacaceae. Our results indicate highest levels Anacampseros, Portulacaria, Ceraria, Talinopsis. Intermediate their were Talinum, Port...
