Common Name The Amambay Habenaria [A Department of Paraguay]
Flower Size .4" [1 cm]
Found in Fr Guiana, Surinam, Brazil and Paraguay in wet savannahs and even semi-aquatic habitats at elevations around 900 meters as a medium to large sized, hot to warm growing terrestrial with a stout, erect stem enveloped completely by leaf bearing sheaths carrying linear-lanceolate, acute to slightly acuminate, glabrous leaves that blooms in the summer on an erect, terminal, to 10" [25 cm] long, many flowered inflorescence with lanceolate, acuminate, erect-patent, shorter than the ovary floral bracts.
+"This species is similar to H. repens but differs by the size of the flowers and length of the lateral segments of the petals and lip (about 12-15 mm in H. amambayensis vs. ca. 4-7 mm in H. repens). In the type material and original description of H. marupaana, plants and inflorescences are shorter and the lateral segments of the petals and lip less developed than in H. amambayensis. However, these caracters are somewhat variable in H. amambayensis and the two species agree well in all of the other details of flower morphology. Habenaria amambayensis is also similar to H. schomburgkii and the exact distinction between the two species is not completely clear. The flowers of H. amambayensis are completely green and the species is typical of marshes and permanently humid places, usually with water over the soil."
