Common Name The Arbacea Lepanthes [Named for the order Arbacea, the sea urchins, of Echinodermata, referring to the lip]

Flower Size .28" [7 mm]

Found in Pasco department of Peru as a miniature sized epiphyte with slender, erect ramicauls enveloped by 10 to 15 sparsely ciliate lepanthiform sheaths with dilated ostia and carrying a single, apical erect, coriaceous, broadly elliptical-ovate, obtuse, shortly acuminate, rounded and contracted below into the petiole base leaf that blooms on an erect, borne behind the leaf, peduncle slender, 1.2 to 1.8" [3 to 4.5 cm] long, rachis .4 to .6" [1 to 1.5 cm] long, congested, successively single, many flowered inflorescence with oblique, as long as the pedicel floral bracts.

"Characterized by a broadly elliptical-ovate leaf borne by a longer ramicaul. The raceme is short, congested, suc-cessively many-flowered, and borne beyond the tip of the leaf by a slender peduncle from behind the leaf. The sepals are carinate-erose and cau-date. The petals are transversely bilobed with a caudate lower lobe. The blades of the lip, borne by broad connectives, are densely long-ciliate the two appearing suborbicular, suggesting a species of sea urchin." Luer 2002
