Common Name The Long-Tailed Habenaria

Flower Size 2" [5 cm]

Found in Guyana, Fr Guiana, Surinam and Brazil in palm swamps and edges of rivers and ponds at elevations of 50 to 1200 meters as a medium sized, sub-aquatic, hot to cool growing terrestrial with to 8, clear green, distichous leaves grading into bracts above that blooms in the late fall and early winter on an erect, terminal, 2 to 16 flowered inflorescence.

+"Habenaria longicauda is characterized by the long spur (13-20 cm) and long stigmas (6-7 mm) with involute margins. It is similar to H. nabucoi, but distinct by the lateral sepals reflexed (vs. not reflexed in H. nabucoi), flowers light green (vs. pure white in H. nabucoi), the midlobe of rostellum completely enclosed between the anthers (vs. partially exposed) and the spur acuminate, with an acute apex (vs. thickened and rounded). The species is typically aquatic, and occurs in water at the margins of lakes, streams and rivers. For more information about the species taxonomy and distribution see Batista et al. (2006)."

The subspecies H longicuda ssp ecalcarata is basically the same as the type but lacks a spur.
