Dendrobium sulcatum Lindl. 1838 is an epiphytic growing orchids species native to the Himalayas, South China, India (Assam) Myanmar (formerly Burma), North Thailand and Laos.

Dendrobium sulcatum racemes consist of up to 20 short-living, yellow flowers. The botanical name sulcatum (sulcatus) refers to the sulcate or furrowed lip of the orchid flower. Single Dendrobium sulcatum flowers get a size of 2,5 - 3,5 cm. Flowering period: March - April. Dendrobium sulcatum orchids are considered as challenging plants and can´t be recommended for orchid beginners, as they require a lot of light, but no direct sun and a balanced temperature and humidity. Dendrobium sulcatum orchids are protected by CITES Appendix II (trade controlled to avoid use incompatible with species survival). Callista sulcata (Lindl.) Kuntze 1891 is used as an accepted synonym.
