Common Name or Meaning The Saccate Lip Pleurothallis [refers to the concave labellum lip]
Flower Size .4" [1 cm]
Found in Chiapas state of Mexico and Quetzaltenngo department of Guatemala at elevations of 1250 to 2400 meters as a mini-miniature sized, cool to cold growing, caespitose epiphyte with slender, erect ramicauls enveloped by a tubular sheath in the lower half and 1 to 2 others at the base and carrying a single, apical, erect, thickly coriaceous, elliptical-oblong, subacute, cuneate and sessile base leaf that blooms in the fall and winter on an successively single flowered inflorescence arising through a spathe with the peduncle concealed within and carrying thin tubular, just shorter than the pedicel floral bracts and carrying a resupinate flower.
"Characterized by the thick narrow leaf that is cuneate at the base and the dorsal sepal and the synsepal are broadly obtuse, the petals spathulate and the oblong, obtuse lip has a central cleft and erect basal angles."Luer 2005
All three of the above forms appear to be P saccatilabia so it seems that it can be quite variable in flower form and colors.
