Full shadeHot Warm Winter Spring Summer Fall

Common Name or Meaning The Spear-Like Lip Platystele

Flower Size .2" [6mm]

Found in Costa Rica on mossy small branches in wet montane forests at elevations around 100 to 1150 meters as a miniature sized, hot to warm growing epiphyte with erect, slender ramicauls enveloped by 2 to 3 thin, imbricating tubular sheaths and carrying a single, apical, erect, coriaceous, narrowly elliptical-obovate, subacute to obtuse, narrowly cuneate below into the indistinct petiolate base leaf that blooms at any time of the year on an erect, strict, loose, distichous, to 3.2" [to 8 cm] long including the slender .8 to 1.2" [2 to 3 cm] long peduncle, simultaneously several flowered, racemose inflorescence arising laterally from the ramicaul with oblique floral bracts.

Many sources cite this species as a synonym of P oxyglosa but I have left them separate at this time. P lancilabris differs from P oxyglossa by being endemic to Costa Rica, larger in size, a strict, nearly simultaneously opening flowering inflorescence instead of flexuous and successively flowered, The sepals and petals are acute and not acuminate and shorter than P oxyglossa as well as the lip is lanceolate, not acuminate and there is a large gelion at the base.
