Phosphatase activity was totally absent on Hyoscyamus foliar hairs, certain activity was usually found in three other semidesert taxa, and a strong response occurred in Drosophyllum. Roridula exhibited only epidermal activity. However, out of all six species, only Roridula and Drosophyllum took up nutrients (N, P, K, Mg) from applied fruit flies. Digestion of prey and absorption of their nutrients are the major features of the carnivorous syndrome. Accordingly, Roridula and Drosophyllum appeared to be fully carnivorous whereas all other examined species are non-carnivorous.
