Abstract

The Epidendrum ellipticum alliance is a critical group among the Brazilian orchid species due to wide variability in the morphology of the flowers. Results of more than 250 floral analyses carried out, with the improved method of Alves from 1990 are presented. Material analysed was collected in the field over a period of five years. Attempts to correlate some variations with environmental factors have been made. The present paper is preliminary.
