Common Name The Large Lepanthes [refers to the plant]

Flower Size .2" [5mm]

Found in Colombia, Ecuador and Peru as a medium to large sized [largest in the genus], cold growing epiphyte at elevations of 2600 to 3400 meters in wet cloud forests with erect, stout ramicauls enveloped basally by 11 to 16 microscopically scabrous lepanthiform sheaths carrying a single, apical, erect, coriaceous, oblong-ovate, subacute to obtuse, acuminate leaf with the rounded base contracted into a petiole and blooms in the winter and spring on 1 to several, slender, simultaneous, congested, distichous, 3.2 to 4.4" [8 to 11 cm] long, including the .8 to 1.2" [2 to 3 cm] long peduncle, racemose, successively several, many flowered inflorescence arising from behind the leaf.

"Characterized by the habit that can produce one of the largest of the genus, but many plant only attain half the apparent maximum size. Thisck coarse roots support stout ramicauls that sometimes reach 20" [ 50 cm] long. The leaveds vary in size with the strength of the ramicaul, but large leaves 6" [15 cm] long are not rare. Yellow orange, flat flowers, sometimes in profusion, are produced on congested racemes behind the eleaf. The sepals are obtuse with short tails. The bilobes petals and bilaminate lip are not remarkably different from many others." Luer 1996

Although the smaller flowered L macrantha is similar, L gargantua has the petals with an oblong, rounded upper lobe without the apiculum between the lobes.
