Description
|
Erect, terrestrial herbs, with 1 or 2 broadly plicate leaves, the basal portions forming a stout sheathing petiole and enclosing a short, stout, subconical tapering pseudobulb. Inflorescences erect, subcapitate or racemose, equaling or exceeding the leaves, the base enveloped by one of the leafless petiolar bracts. Flowers few to many, of small to medium size, borne on short or elongate pedicels, subtended by short or elongate bracts. Sepals subequal, connivent at the base, the dorsal sepal concave, erect, the laterals more or less falcate or decurved, adnate to the foot of the column, forming a mentum. Petals subequal to the lateral sepals. Lip entire, somewhat concave at the base, spreading, articulated to the foot of the column. Column arcuate, auriculate near the apex, or broadly winged throughout its length; base produced into a short foot. Anther terminal, operculate, incumbent, 1-celled; pollinia 4, waxy.

Note
|
A few American terrestrial orchids of remarkably uniform vegetative and floral structure. It seems evident that relatively trivial differences in size, color, length of the raceme, and geographic locality have been considered as adequate for the segregation of most of the so-called species. Only two entities 'showing any consistent structural differences are known to occur in Panama, where they seem to be confined to the Chiriqui highlands. The sterile plants greatly resemble those of Calanthe mexicana.
