Dendrobium-vexillarius-Purple-Flame-CHM/AOS-2024-03-12 *SITF confirms that this plant is Dendrobium vexillarius (Apr 2024).
A key discriminator for D. vexillarius is the three-winged ovary that can be clearly seen in this plant. The award description indicates this plant is an intervarietal cross between var. microblepharum and var. retroflexum; therefore it is confirmed without a subspecies designation; however, this plant does display the color form of var. microblepharum. This plant closely matches the photo by Ed de Vogel and the Orchids of New Guinea website as shown in the IOSPE.

Dendrobium-sinominutiflorum-Little-Green-Gem-2023-07-13 *SITF has determined this plant to be Dendrobium compactum, not Den. sinominutiflorum (Aug 2023).

Den. sinominutiflorum has lip side lobe apices sharply dentate and margins entire or margins inconspicuously notched; the lip has three keels which merge to form a broadly thickened fleshy ridge. These characteristics are not seen on this plant. This plant matches the photo of Den. compactum in the OW and Baker and Baker's description of Den. compactum in "Orchid Species Culture: Dendrobiums". The flower size and color also match Den. compactum.

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