Common Name The Insignificant Habenaria

Flower Size 1.2" [3 cm]

Found in Guyana, Fr Guiana Surinam and northern and central Brazil in open grasslands as a small sized, cool growing terrestrial with an erect stem carrying remotely spaced, linear, acute, basally clasping bracts that blooms in the later spring on a 1 to 2 flowered inflorescence

+"In the general morphology of the flowers this species is similar to H. trifida, but distinct by the vegetative parts. In H. macilenta the plants are usually more slender and shorter (13-43 cm tall vs. (24-)40-76(-94) cm tall in H. trifida), the leaves 4-10 x 0.4-1.1 cm (vs. 9-20 x 0.9-2 cm in H. trifida), the larger leaves are usually on the lower part of the stem (vs. the larger leaves concentrated on the middle of the stem in H. trifida) and the internodes usually larger than the leaves (vs. smaller with the internodes usually covered by the leaves in H. trifida). Other differences are the the shorter pedicel (1.5-3 cm long vs. 3-9.5 cm in H. trifida), the color of the petals and lip (yellowish vs. white in H. trifida) and column structure (Batista & Bianchetti 2002). Sepals are green and the petals and lip yellowish. The species grows in marshes or seasonally humid places."
