Name: Gastrochilus calceolaris (Buch.-Ham. ex Sm.) D.Don

Synonyms: Aerides calceolaris Buch.-Ham. ex Sm.; Saccolabium calceolare (Buch.-Ham. ex Sm.) Lindl.

Etymology: The genus name combines Greek words for “belly” and “lip” and describes the sac-like labellum. The epithet calceolaris means “shoe-shaped” and also refers to this characteristic form.

First description: David Don placed the species in the genus Gastrochilus in 1825.

Origin/Distribution: South and Southeast Asia, from the Himalayan region through southern China and Indochina to parts of the Malay Archipelago.

Location/Habitat: Epiphytic in moist forests at lower to montane elevations, frequently between approximately 900 and 2,300 m. The species prefers bright, filtered light, high humidity, and intermediate temperatures of approximately 15–25 °C.

Description and notes: Gastrochilus calceolaris grows monopodially and bears fleshy, distichously arranged leaves. Short, panicle-like inflorescences emerge from the leaf axils and bear several yellowish-green, reddish-brown spotted flowers. The white, fringed lip has a striking yellow, shoe-shaped cavity. A mounted culture or a small basket with very airy substrate is particularly suitable. We water regularly, but allow the roots to dry out quickly afterward and ensure good air circulation.
