SUBGENUS Pleurothallis SECTION Pleurothallis SUBSECTION Antenniferae 1998

Characterized by the caespitose to repent habit with well developed ramicauls that are usually longer than the leaf. They have a mostly erect, racemose, termianl inflorescence at the base of the sessile or rarely subpetiolate base leaf. Basically the flowers are similar and resupinate with the dorsal sepal free from the laterals and the laterals are connate into a concave to cucullate synsepal. The petals are more or less thickened and entire, narrowly oblong to narrowly linear and are expanded, The three lobed lip has prominent lateral lobes that are either broadly rounded or elongated often markedly so. The lip is variously recurved towards the middle usually markedly so from 90 to 180 degrees. There is generally not a glenion present and the deflexed base of the lip is attached to an abbreviated column foot. The column is semiterete, usually short and has an apical to subapical anther and stigma. SUBSECTION TYPE Species
