Common Name The Blunt Habenaria
Flower Size .8" [2 cm]
Found in Surinam, Fr Guiana, Guyana, Venezuela, Antioquia, Norte de Santander, Santander and Valle de Cauca departments of Colombia, Peru, Brazil, Argentina and Paraguay in savannahs and burned areas in forests at elevations around 100 to 3200 meters as a small to large sized, hot to cold growing epiphyte with an erect stem carrying clear green, lanceolate to ovate-lanceolate, acute to the lower ones obtuse, amlexicaul, acuminate, acute, narrowing into the tubular base leaves that blooms in the late summer and early fall on an erect, 4 to 10" [10 to 25 cm] long, racemose, many [10 to 18] flowered inflorescence with large, oval-lanceolate, longer than the flowers floral bracts.
Similar to H seticauda but differ in the spur length which is 2.2 [5.5 cm] in H obtusa and 3.2 to 4.4" [8 to 11 cm] long in H sticauda. Both taxa are similar to H hamata but differ in the arrangment of the flowers which is close and parallel to the inflorescence axis versus spreading in H hamata and the imbricate bracts that usually cover the rachis and the spur."
