Dendrobium-venustum-CCE/AOS-2023-06-28 *SITF has determined this plant to be Dendrobium delacourii, not Dendrobium venustum (Jul 2023).

Posted on June 28, 2023

Finding
The key difference between D. venustum and D. delacourii is the plant size. There are three species with very similar flowers; these are D. delacourii, D. simondii, and D. venustum. They differ in plant size where D. delacourii is the smallest, most compact plant of the three having canes less than 10cm and D. venustum the largest having canes up to 60 cm long. This compact plant is D. delacourii with pseudobulbs measuring only 2 to 5 cm long. Supporting photos can be found in the IOSPE, OW and orchidroots.com. This plant is an excellent match to the D. delacourii description in Baker and Baker's, "Orchid Species Culture: Dendrobium".
