Common Name

Flower Size 1" [2.5 cm]

Found as a large sized, hot to warm growing epiphyte in Veracruz and San Luis Potosi, Mexico with small pseudobulbs carrying a single, erect, narrowly elliptic, keeled ventrally leaf that blooms in the late summer and fall on an erect, to 4' [120 cm] long, erratically branched, racemose, many flowered inflorescence with successive opening flowers arising from a basal leaf sheath. The flowers are about 1" in diameter, and according to Weyman Bussey this species is a variant of Onc. luridum or Onc. carthagenense or a separate species. I have all three species and can see differences in habit, inflorescence like in this one that has a very erect spike and only becomes slightly arcuate as the large flowers open and bloom times.
