LATE 
Common Name Schwacke's Habenaria [German Mining Engineer and Orchid Enthusiast 1800's]
Flower Size 1.4" [3.5 cm]
Found in Colombia, Venezuela, Guyana, French Guiana, Surinam, Brazil and Paraguay in littoral savanna and wet to inundated savannahs at elevations of 300 to as a medium sized, warm to cool growing terrestrial with an erect, slender, delicate stem enveloped laxly by 5 to 7, strongly amplexicaul, linear, acute, grasslike leaves that blooms in the late spring on a terminal, erect, more or less secund, 2.4 to 4" [6 to 10 cm ]long, 6 to 10 flowered inflorescence with lanceolate, acuminate, a third as long as the ovary floral bracts.
+"Renz (1992) included H. amazonica under the synonymy of H. platydactyla. The examination of the type material of the two species and a large number of live and dried specimens from central Brazil and Paranį have confirmed the position held by Renz and shown that both species are identical to H. schwackei. The species is similar to H. heptadactyla and H. leprieuri, but distinct by the conspicuous pedicels (about 8-9 mm vs. 2-3 mm long in H. leprieuri and H. heptadactyla), the green sepals and white petals and lip (vs. the yellow petals and lip of H. heptadactyla and the green petals and lip of H. leprieuri), and the frequently broad lateral segments of the petals and lip (up to 2 mm broad vs. 0.5-0.75 mm broad in in H. leprieuri and H. heptadactyla). Habenaria schwackei is typical of seasonally humid places."
Synonyms Habenaria amazonica Schltr.1925; Habenaria platydactyla Kraenzl. 1911
