Common Name The Umbellate Platystele [refers to the inflorescence]

Flower Size 1/32" [2mm]

Found in Antioquia department of Colombia at elevations of 600 to 1600 meters as a miniature sized, warm to cool growing epiphyte with erect, slender, ramicauls enveloped basally by 2 to 3 thin, ribbed, imbricating sheaths and carrying a single, apical, erect, coriaceous, elliptic-spathulate, rounded, cuneate below into the petiolate base leaf that blooms in the winter and spring on a very congested, umbellate, simultaneously 5 to 9 flowered, .44 to .64" [1.1 to 1.6 cm] long including the .4 to .6" [1 to 1.5 cm] long peduncle, racemose inflorescence arising from above the middle of the ramicaul and has loose, imbricating, oblique, as long as the ovary floral bracts.

"The umbel is composed of several, overlapping, minute, simultaneous flowers, one of the smallest of the genus. The tiny, obtuse sepals and petals are ciliate and the ovate, cellular-glandular lip is a trifle larger that the lateral sepals, the margins are not revolute and the apex is rounded," Luer 1990

Similar to Platystele ortiziana, P beatricis, and P dasyglossa as thay all have umbellate inflorescence.
