to 
Southern Hemisphere
Common Name The Purple Seamed Oncidium
Flower Size about 1 1/2" [3.75 cm]
Found in Espirito Santo, Sao Paulo and Rio states of Brazil in the cool mountain ranges of as a medium sized, cool growing epiphyte with clustered, oblong to elliptic, laterally compressed pseudobulbs carrying 2 apical, leathery, lanceolate, obtuse leaves that blooms in the summer in the southern hemisphere on a basal to 48" [122 cm] long, arching, paniculate, many flowered inflorescence with 1 to 4 branches each carrying 3 to 6 fragrant flowers.
It differs from Onc. crispum and O gardneri by having a "witch's nose" on the Lip.
The O crispum complex includes O praetextum, O curtum, O enderianum and O gravesianum, and all are now referenced as synonyms of Oncidium crispum. I have left them separate because they have been known as separate species for centuries.
