The genus "Anguloa", commonly known as Tulip Orchid, is a taxon of orchids closely related to "Lycaste". The genus is named after Francisco de Angulo, a Peruvian orchid lover. Its abbreviation in horticultural trade is Ang.

Description

This genus is found on the forest floor at high elevations from Venezuela, Colombia, Ecuador to Peru.

They are rather large terrestrial and sometimes epiphytic orchids with fleshy pseudobulbs longer than 20 cm. The long, lanceolate and plicate leaves of a full-grown "Anguloa" can be more than 1 m long. Two to four leaves grow from the base of each pseudobulb. The leaves are deciduous, and are shed at the start of each new growth.

The flowers of these orchids have a waxy appearance and come in two colors : greenish white and yellow to red. A single flower per inflorescence arises from the base of each new pseudobulb. The white Anguloas have six inflorescences per pseudobulb, the other can produce up to twelve inflorescences. The sepals have a bulbous shape, resembling a tulip. The lip is three-lobed. The column has four pollinia.

The flowers have a strong scent of cinnamon.
