Pleurothallis masdevalliopsis Luer 1979 SUBGENUS Masdevalliantha Luer 1986 Drawing by Carl Luer and The Swiss Orchid Foundation at the Jany Renz Herbaria Website

Full shade Cold Summer

Common Name or Meaning The Masdevallia-Like Pleurothallis

Flower Size .8" [2 cm]

Found in Ecuador in scrub cloud forests at elevations around 2500 meters as a mini-miniature sized, cold growing epiphyte with stout, erect ramicauls enveloped by 2 tubular sheaths and carrying a single, apical, erect, thickly coriaceous, elliptical-linear, narrowly obtuse, narrowing below intothe subpetiolate base leaf that blooms in the summer on a slender, .6 to .8" [1.5 to 2 cm] long, single flowered inflorescence arising from the ramicaul below the apex.

CAUTION All photos that I can find on the net marked Pleurothallis masdevalliopsis are actually Pleurothallis longiserpens from Peru. The lip apex of P masdevalliopsis is loosely and sparsely fringed and the base of the lip is deeply concave and accomodates a finger like extension of the tip of the column foot. There are also a pair of calli below the middle of the lip which is cleft in between. We need photos of the side of the flower showing the lip detail.

All photos on the net of P masdevalliopsis are actually Pleurothallis longiserpens. P masdevalliopsis has a broadly falcate side lobe of the lip and P longiserpens has an ovate side lobe. The vegetative parts of P masdevalliopsis will also be with a very short .2 to .4" [5 to 10 mm] ramicaul and aand have a subpetiolate base to the narrowly obtuse leaf. P longiserpens has a .8 to 2" [2 to 5 cm] long ramicaul.
