The orchid in these images is the Trichocentrum cavendishianum - Cavendish's Lophiaris, photographed in Cuba. This species is native to Central America from Honduras north into Central Mexico.
Synonyms include Lophiaris cavendishiana and Oncidium cavendishianum and while most sources do not list a common name, I did find it occasionally refered to as Cavendish's Lophiaris.
This is an epiphytic orchid with very small psuedobulbs surrounded by several scarious sheaths arranged in two ranks vertically (distichous). Each psuedobulb has a single, broadly elliptic to lanceolate erect leaf. The many-flowered panicle rises up to 1m (~3 ft.) from a newly matured psuedobulb. The showy flowers are mostly yellow with brownish markings.
