Part shade HotFall

Common Name The Small Bird Habenaria

Flower Size

Found in Colombia, Peru, Venezuela and Brazil at elevations of 200 to 260 meters as a medium sized, hot growing terrestrial with an erect stem carrying 7 to 10, oblong-lanceolate to narrowly elliptic, acute leaves clustered towards the middle of the stem that blooms in the fall on a terminal, erect, to 5.2" [13 cm] long,loosely to 15 flowered inflorscence with shorter than the ovary floral bracts.

+"This species is similar to H. leptoceras Hook., found in the Atlantic forest and " restingas" in the states of Rio de Janeiro, Espirito Santo and Bahia in southeastern Brazil. However, in H. avicula, similarly to H. alterosula, the leaves are concentrated on the middle or upper part of the stem and the lateral segments of the lip range from about 1 mm long to almost absent. In H. leptoceras the leaves are better distributed along the stem or concentrated on the lower part, and the lateral segments of the lip are (2-)3-4 mm long. The only collection of H. avicula known from Brazil was collected in a " caatinga" on white sand, a vegetation similar to the coast sandy " restingas" , where H. leptoceras is typically found. Flowers are recorded as green and white."

H patentiloba is often cited as a synonym of H avicula but I feel that they may be different with H avicula being only in northern South America and H pateniloba only in Panama. The most distinguishing characteriztic is the leafy throughout stem in H patentiloba and the stem carrying leaves clusteresd towards the middle of H avicula.
