Part shadeHot Fall

Common Name The Toothed Habenaria

Flower Size .8" [2 cm]

Found in Ecuador, Peru and west central Brazil in upper elevation grasslands as a large sized, cold growing terrestrial with erect, leafy throughout stems carrying a few to several, cauline, ovate-lanceolate to elliptic-lanceolate, acute, basally clasping leaves that blooms in the fall on an erect, terminal, scapose, 8" [20 cm] long, loosely several flowered inflorescence with lanceolate, acuminate, spreading bracts.

+"This is an uncommon species in Brazil known just from the two collections mentioned above. The specimen in the collection Pires & Silva 8058 was identified by Pabst (1962) as H. odontopetala Rchb. f. However, although the two species are similar, the flowers of H. dentifera have a prominent anterior petal (ca. 2 mm long) about half the length of the posterior petal (vs. reduced to a denticulate projection ca. 1 mm long and about 1/5 the length of the posterior petal in H. odontopetala). The species occurs in forests or " caatinga" and the flowers are recorded as green."
