EARLIER

Common Name Hwang's Lepanthes [honors Joanne Hwang Pemberton, wife of Robert W. Pemberton, generous donor to the expansion of the natural reserve that protects the habitat of the new species current]

Flower Size .08" [2 mm]

Found in Antioquia department of Colombia in primary and secondary forests on thin, moss covered branches at elevations around 2100 meters as a mini-miniature sized, cold growing, caespitose epiphyte with suberect, slender ramicauls enveloped by 7 to 9, acuminate, ribbed, microscopically ciliate lepanthiform sheaths and carrying a single, apical, abaxially purple, elliptical, acute, incised and tri-apiculate apically, contracted below into the cuneate base leaf that blooms in the earlier winter on a filiform, terete peduncle up to .2" [5 mm] long borne near the apex of the ramicaul, held on the abaxial surface of the leaf, rachis .16 to .28" [4 to 7 mm] long, up to 1/2 the length of the leaf, congested, distichous, successively single, many-flowered inflorescence with a conical, ciliate, acuminate, shorter than the pedicel floral bract.

"Lepanthes hwangiae is most similar to L. cyclochila but it can be distinguished by its transversally bilobed petals with the upper lobe bifurcate in unequal lobes, with the external lobe triangular, obtuse and the internal lobe oblong, obtuse (vs. the upper lobe obliquely truncate) and the lower lobe oblong and rounded (vs. lower lobe oblong, shallowly bifurcate into 2 triangular, narrowly rounded lobes) and the lip sub-circular, slightly emarginate, with the oblong and rounded basal lobes erect, embracing the column and touching each other well above the column (vs. sub-quadrate, markedly emarginate, with the shortly triangular and obtuse basal lobes of the lip erect on each side of the column without touching each other). Lepanthes hwangiae is also similar to Lepanthes petalopteryx , but this latter species could be recognized by the petals with both lobes similar, obliquely subquadrate or oblong, oblique, with the inner angles shortly acuminate-obtuse, the outer angles subacute, the outer angles obtusely angled at the center (vs. the upper lobe oblong bifurcate in unequal lobes, the external lobe triangular, obtuse, the internal lobe oblong, obtuse and the lower lobe oblong, rounded). Finally, the lip in L. petalopteryx is reniform with the lobes surrounding the column without touching each other (vs. sub-circular, embracing the column and touching each other well above the column)."
