Common Name or Meaning The Two Lobed Lepanthes [refers to the lip]

Flower Size .2" [5 mm]

Found in Colombia and western Ecuador in cloud forests at elevations around 2100 to 3600 meters as a miniature sized, cold growing epiphyte with slender to stout, erect ramicauls enveloped by 5 to 17, minutely ciliate-scabrous lepanthiform sheaths and carrying a single, apical, erect, thinly coriaceous, elliptical-oblong to elliptical ovate, acute to obtuse, shortly or slightly acuminate, cuneate below and contracted into the petiolate base leaf that blooms at any time of the year on a slender, distichous, to 1.6" [to 4 cm] long, filiform, successively many flowered, racemose inflorescence arising from behind the leaf.

"Variable bot vegetatively and florally. The inflorescence of Lindley's type is incompletely developed, being no longer than the leaf. The shape of the leaf varies from oblong and obtuse to ovate and acute with all the intermediate shapes found all through the distribution. Some forms grade into L elongata. The loose flexuous racemes sometimes begin flowering shorter than the leaf but continue lengthening to far surpass the leaf. The flowers are small, bilabiate and variable in color, but often yellow, with small red to purple petals and lip. The degree of pubescence of the petals and lip varies. The lobes of the petals are triangular, but often the apices are acuminate. The body of the lip is broad and connate to the column near the base. The appendix is small, pubescent and oblong with the tip rounded but sometimes bilobed. L oxypetala is similar but distinct with its long-acuminate petals as well as the lip attached to the slender shaft of the column above the middle." Luer 1996
