Common Name The Two-Horned Masdevallia

Flower Size 1 1/16" [3 cm]

Found in southeastern Ecuador at elevations of 700 to 1000 meters as a small sized, warm growing epiphyte with short, stout, erect ramicauls that are enveloped by 2 to 3 loose, tubular sheaths carrying a single, apical, erect, thinly coriaceous, narrowly elliptic-obovate, subacute, leaf with the base narrowly cuneate into the petiole that blooms with a solitary, nutant flower sometimes followed by a second carried by a scurfy, suberect to horizontal to pendant, 4 3/4 to 9 1/2" [12 to 24 cm] long inflorescence arising from near the base of the ramicaul with 3 distant bracts and a tubular oblique floral bracts holding the flower above the leaf.

Unique to the Masdevallia as this species is densely covered with branching, scaly trichomes similar to those in Scaphosepalum and was used by Königer & J.J. Portilla to exclude this species from Masdevallia and make a monotypic genus, Portillia, Carl Luer feels that as the flowers fit into the unispecific subgenera of Scabripes, there are not enough sufficient differences to segregate it, So we keep it in Masdevallia.

Synonyms Portillia popowiana Königer & J.J. Portilla 1996
