A COMPARATIVE NUMERIC ANALYSIS OF THE SECRETORY TRICHOMES BELONGING TO THE FOLIAR LIMB IN SOME DROSERA SPECIES

The paper is focused on a comparative numeric analysis of the secretory pedicelate (tentacular) trichomes of the upper epidermis of the leaf in 16 Drosera species and of the sessile secretory trichomes belonging to both upper and lower epidermis in the same species. The bigger is the number of the secretory trichomes, in both epidermises, the more efficient is the plant in capturing and retaining different organisms. This way, the carnivorous plants can completely benefit by the nutritive compounds resulted from the preys.
