Found in Sao Paulo, Rio de Janiero and Minas Gerais states of southeastern Brazil in primary mossy cloud forests at elevations of 900 to 1600 meters as a mini-miniature, cool growing epiphyte most often found growing on Vellozia trees on high windy slopes with an erect ramicaul carrying a single, coriaceous, narrow, acute, light green, gradually narrowing below into the petiolate base leaf that blooms in the spring and again in the fall on erect, short, 4 to 7 flowered inflorescence with an as long as the ovary floral bract and holding the flowers just above the succulent like leaves.
This species and P ourobranquensis are very similar but differs mostly in this one having from 1 to 6 flowers per inflorescence while P ourobranquensis always has 2 flowers.
Characterized by the small plants with pseudolepanthiform sheaths that cover the ramicaul and by the delicate yellow flowers.
