Name: Coelogyne sulphurea (Blume) Rchb.f.

Synonyms: Chelonistele sulphurea (Blume) Pfitzer; Chelonanthera sulphurea Blume

Etymology: The genus name Coelogyne derives from Greek and refers to the sunken or hollow stigma. The specific epithet sulphurea means “sulfur yellow” and refers to the flower color.

First description: Carl Ludwig Blume first described the species in 1825 as Chelonanthera sulphurea; Heinrich Gustav Reichenbach later published the combination Coelogyne sulphurea.

Origin/Distribution: Western Malesia to the Philippines.

Habitat: Epiphytic or lithophytic in moist tropical forests. We cultivate the species in bright to lightly shaded conditions at around 16–26 °C, with high humidity and good air circulation. We keep the airy substrate evenly slightly moist, without waterlogging.

Description and notes: Coelogyne sulphurea produces pseudobulbs with narrow leaves and upright inflorescences bearing several yellowish to sulfur-yellow flowers. An airy orchid substrate that retains a little moisture, along with regular watering during growth, promotes vigorous development.
