Common Name Irma's Lepanthes [honors Irma Tarazona Rubio, mother of Robinson Galindo-Tarazona current]
Flower Size .2" [5 mm]
Found in Valle de Cauca department of Colombia in secondary forests low to the ground along small creeks at elevations around 1700 meters as a mini-miniature to just miniature sized, cool growing, caespitose epiphyte with suberect to horizontal, slender ramicauls enveloped by 8 to 14, acuminate, furrowed and microscopically pubescent lepanthiform sheaths with dilated and ciliate ostia and carrying a single, apical, dark green, more or less horizontal, coriaceous, reticulate-veined, with 8 main veins, corrugate, lanceolate, acute, apex emarginate with an abaxial apiculum in the middle, contracted below into the cuneate base leaf that blooms in the late summer and early fall on a shorter than the leaf, borne on top of the leaf by a filiform, terete peduncle 0.9–1.2 cm long, from near the apex of the ramicaul, rachis to .5 to .9 cm long, congested, distichous raceme, successively single, 6 to 12 flowered inflorescence with acuminate, shorter than the pedicel floral bract.
"Lepanthes irmae resembles a group of species with similar habit and reticulate leaves, such as L. licrophora , L. silverstonei, and L. , but the flower is entirely different from the last species and does not resemble any other described species so far. It can be easily recognized by the combination of dark green reticulate and corrugate leaves, transversely bilobed petals with a middle lobe, and the ovate blades of the bilaminate lip."
