Biologia floral de aristolochia Gigantea mart. et Zucc. (Aristolochiaceae) I

Abstract

In this work we have studied the mecanism of pollination of A. gigantea emphasizing the sapromyophilous aspects of the flower. The anatomic details of the different floral structures which function as attractives for the insects and means of the capture of same have been considered. Among these the pigmentation of perianth, the nectars, the secreting cells responsible for. the emission of odour, some epidermic structures. The behavior of the probable effective pollinater P. kerteszi Enderlein (Díptero of the Phoridae family) on the flower of the A. gigantea was furthermore studied and the occasional pollinater and visitors were identified and recorded their frequency.
