    We studied the foliar hair secretion of phosphatases and the uptake of N, P, K, and Mg from fruit flies as model prey in four species of semidesert plants (Ibicella lutea, Proboscidea parviflora, Cleome droserifolia and Hyoscyamus desertorum) and in Roridula gorgonias and Drosophyllum lusitanicum for comparison. 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.
