Abstract

Philcoxia P. Taylor & V.C. Souza is a recently described genus comprising three species endemic to the Brazilian "campo rupestre" formation. Species of Philcoxia are unique within Plantaginaceae due to their underground stems and peltate, underground leaves that are able to capture and digest small nematodes. Carnivory in P. minensis V.C. Souza & Giul. is a rare condition and the only known case in Plantaginaceae, an ideal study case that allow us to test hypotheses on the evolution of carnivory within Lamiales. This project aims to study Philcoxia from three different approaches: 1) macroevolution - to test its monophylly and relationships among other genera from tribe Gratiolae; 2) microevolution - to study the genetic structure of populations of Philcoxia with the aid of microsatellites; 3) ecophysiology - to test hypotheses concerning the photosynthetic cost of carnivory, and to analyze allocation of resources from the prey as well as parameters from the foliar economical spectrum.
