Many of the synonyms of Schizaea elegans are, in m y opinion, based upon an artificial division of the continuous range of dissection in this species. At least some of the variation may be due to habitat, as shown by the decreasing dissection at higher altitudes in Maguire et al 29966, 29945-A, and 29970, which was observed in the field by Dr. J. J. Wurdack (personal communication). N o such correlation exists for all specimens over the entire range, however, for many large, flabellate specimens have been collected at lower elevations. The smallest specimens with the most highly reduced laminar expansion are sometimes mistaken for S. fluminensis.
