The pitchers of the tropical carnivorous plant Nepenthes alata are highly specialized organs for the attraction and capture of insects and absorption of nutrients from them.This study examined the structure and development of these pitchers, with particular focus on the nectaries and digestive glands.s carefully examined by Darwin (1875) â , carnivorous plants attract and trap insects, then breakdown and absorb the by-products (reviewed in Juniper, Robins, and Joel, 1989 â). Surprisingly different trap morphologies have evolved in carnivorous plants for the capture of insects.
