Oncidium spectatissimum

Long known as Odontoglossum spectatissimum (the plant grown as Odontoglossum triumphans is usually included here), this is a cool-growing Andean cloud-forest orchid from Colombia, Venezuela and Ecuador. It bears branching sprays of large yellow flowers barred with chestnut brown. Like other classic odontoglossums, it needs cool nights, constant moisture and brisk air movement, and it sulks in hot summers.
