Part Shade Hot Warm LATE Summer EARLY Fall

Common Name The Ayanganna Plateau Habenaria [A plateau in Guyana]

Flower Size .4" [1 cm]

Found in Venezuela, Guyana and west central Brazil in savannahs at elevations of 200 to 740 meters as a small sized, hot to warm growing terrestrial with an erect to slightly flexuous, remotely leafy throughout stem carrying 4 to 7, very narrowly linear-setaceous, acuminate, rather short, basally clasping leaves that blooms in the late spring, summer and early fall on a 3.6 to 4.8" [9 to 12 cm] long, laxly 3 to 12 flowered inflorescence with ovate, acute, shorter than the ovary floral bracts and carrying very small, greenish flowers.

+"There is no known material of this species from northern Brazil, however it occurs in Venezuela, where it was collected a few meters from the Brazilian border and reaches the central region of the "cerrado" biome, where it is common in some localities. Thus, it is likely that the species occurs and will eventually be found in northern Brazil, at least in the state of Roraima. Distinctive features of this species are the linear-setaceous leaves, the small flowers (dorsal sepal ca. 3 x 2.5 mm), the ovary which spreads from the rachis and the bracts usually shorter than half the length of the pedicellate ovary, even in the lower flowers in the inflorescence. Flowers are mainly green and the species is typical of humid places. Flowering time in central Brazil as well as in Venezuela occurs at the end of the rainy season."
