Note
|
The description of the flowers is taken from the original publication. No flowers from typical material have been seen but there is an analysis (by Schlechter) in the Ames Herbarium. If the analysis is correct the Costa Rican material, of which flowers are available, belongs to a different species. The Costa Rican material called E. laxus has a lip which is essentially oblong, emarginate, lacks surface papillae of any sort (certainly -lacks the tooth-like "papillae" of Schlechter's analysis and the figure cited); the petals are differently shaped as are the lateral sepals.
