Common Name or Meaning The Prickly Pleurothallis [refers to the lip]

Found in southeastern Ecuador at elevations around 900 meters as a mini-miniature sized, warm growing growing, shortly repent epiphyte with slender, ascending to erect, sharply triquetrous, slightly broader towards the leaf ramicaul enveloped by 2 to 3, thin, tubular sheaths and carrying a single, apical, spreading, fleshy, coriaceous, elliptical, subacute to obtuse, subcordate below into the sessile base leaf that blooms in the summer on a fascile of [3 mm] long, successively single flowered inflorescence arising from a spathe at the apex of the ramicaul held on top of the leaf and carrying a single flower with a yellow, 3 purple striped dorsal sepal, purple lateral sepals, yellow petals and a black lip.

CAUTION All photos on the net of this species are incorrect, most have a simultaneous fascile of flowers instead of a successive single flowered inflorescence, Also the real P aculeata has a yellow, three purple striped, dorsal sepal, purple lateral sepals, fimbriate margined petals and a black to purple lip with a obtuse apex.
