Common Name The Birds Beak Oncidium

Flower Size 3/4" [to 2 cm]

Found in Mexico, Guatemala, El Salvador, Nicaragua, Costa Rica and Panama in humid forests at altitudes up to 1500 meters as a miniature to small sized [plant only], cool to warm growing epiphyte with oval, compressed, 2 1/2" [6 cm] pseudobulbs that are fairly closely grouped on the rhizome and as a rule there are two apical, flexible, curved, linear-lanceolate, 8" [20 cm] leaves. The basal, curving or pendulous, to 2' [60 cm] long, dense and branched, strongly arched panicle, sometimes two to a mature pseudobulb, arise in the fall and winter and have numerous fragrant vanilla, grape, baby powder, spicy, cinnamon, cocoa and candy scented, longlasting flowers.

I mounted this species on cork and it thrives, many times blooming more than once a year and likes a semi-winter rest .

CAUTION!!!!!!This orchid for most of the last 200 years has been known as Oncidium ornithorhynchum which with recent studies has been found to describe a yellow flowered species from Andean South America known commonly as Oncidium pyramidale. A new name was needed for the pink, highly fragrant flowers that occur in Central America hence this new name Oncidium sotoanum for the species in the photos above.

Synonyms Oncidium sotoanum f. albiflorum (Rchb.f.) Lückel 2014; Oncidium sotoanum subsp. papalosmum R.Jiménez 2010
