Common Name The Broom Pleurothallis [refers to the fascile of inflorescence]
Flower Size .4" [1 cm]
Found in Cordoba department of Colombia in cloud forests at elevations around 2800 to 3100 meters as a small sized, cold growing epiphyte with stout, erect ramicauls enveloped with 2 or more tubular sheaths at the base and carrying a single, apical, erect, coriaceous, obovate, obtuse, shortly acuminate cuneate below and decurrent into the petiolate base leaf that blooms in the winter, on an arising from the middle of the leaf, free for 1.4 to 2.4" [3.5 to 6 cm], before the dense fascile of numerous, .12 to .2 [3 to 5 mm] long, single flowered inflorescence subtended by a spathe with an annulus arising from the tip of the free, vascular bundle with oblique inflated floral bracts.
"The large obovate leaf with the ramicaul embedded within the lower half and then with the svascular bundle of the inflorescence free to near the apex of the leaf is distinctive. At the tip of the ffree portion a densely fasciculate mass of peduncles and pedicels accumulates, resembling a small shaving brush. The flowers are produced singly and in succession. The sepals and petals are most similar tothose of Pleurothallis scoparum and Pleurothallis tetroxys . The long attenuate apex of the lip is most distinctive." Luer 1992
