This orchid breed is native to tropical climates and does best around 65 to 80 degrees. Between one and a large number of resupinate or non-resupinate flowers are arranged along an unbranched flowering stem and may be short or long-lived. The flowers may be white, green, yellow, or pink to purple, often with contrasting colours in the labellum. The sepals and petals are usually free from and more or less similar to each other but markedly different from the labellum. The labellum is more or less egg-shaped, with the narrower end towards the base and flanks the column. There is often a callus consisting of narrow, parallel ridges, in the centre of the labellum.
