Common Name del Hierro's Masdevallia [Ecuadorian discoverer of species - Current]

Flower Size 1 1/4" [3.2 cm]

Found in east central Ecuador as a small sized, cool to cold growing epiphyte at elevations of 1500 to 2600 meters with stout, erect, ramicauls enveloped by 2 to 3 loose, tubular sheaths carrying a single, apical, erect, coriaceous, narrowly elliptic, subacute leaf that is narrowly cuneate below into the petiole and blooms in the fall on a stout, erect, 4 3/4" to 5 1/2" [12 to 15 cm] long, single flowered inflorescence arising from low on the ramicaul with a bract near the base and an inflated, broadly ovate, concave floral bract holding the flowers near leaf height. Differs for the other members of this section Cucullatia which have a large, inflated, hood-like floral bract engulfing the pedidel, ovary and base of the sepaline tube. ALso by its consistently pure yellow flowers with sepals that are smooth within

Said to be consistently yellow but the 3rd photo is of a darker colored flower and is close to M dehieroi but differs in the color, shape of flower and in the petals and the apex of the lip. It fits here beter though than within any of the other Ecuadorian members of the section Cucullatia. It very well may be a new species.
