Common Name The Very Tiny L calodyction Lepanthes

Flower Size .04” [1 mm]

Found in Valle de Cauca department of Colombia in secondary vegetation on the western slope of the Western Cordillera at elevations around 300 to 640 meters as a mini-miniature sized, .8" [2 cm] tall, hot to warm, caespitose growing epiphyte with slender, erect ramicauls , enveloped by 5 to 6, microscopically ciliate-scabrous lepanthiform sheaths carrying a thinly coriaceous, light green, heavily reticulated with purple, subcircular to broadly ovate, broadly obtuse, with a marginal vein, margins undulate and velvety, cordate and abruptly contracted below into the petiolate base leaf that blooms at least in the later spring on a a congested, distichous, borne on top of the leaf, peduncle slender to .08" [2 mm] long, up to .12 to .16" [3 to 4 mm] long overall, successively single, several-flowered inflorescence with echinate, as long as the ovary floral bracts.

"Most similar to L calodyction but is easily distinguished by its its unique very small, diminutive flowers and plants; petals with the margin velvety (vs. ciliate) acaudate (vs. long caudate), and the lip transversely reniform (vs. transversely oblong-reniform)." J.S.Moreno & Banquero 2020

"Lepanthes microcalodictyon belongs to an informal group of species from the lowlands of the Pacific Ocean in South America and Panamá, characterized mainly by having heavily reticulate leaves (except for the Panamanian species Lepanthes pantomima Luer & Dressler and its synonym Lepanthes arachnion Luer & Dressler; (Baquero, 2018) with margins undulate, small flowers with caudate petals, lip transversely reniform, oblong, cordate, and without an appendix, connectives and body. Several species, such as L calodictyon, Lepanthes pretiosa Luer & Hirtz, L. volador Luer & Hirtz, L. barbelifera Luer & Hirtz, L. tentaculata Luer & Hirtz, L. tortuosa Luer & Hirtz, L. bibarbullata Luer, L. saltatrix Luer & Hirtz and the recently described species L. kayii L. Baquero." Baquero, 2018
