Dendrobium-tipuliferum-2023-10-04 *SITF confirms this plant is Dendrobium tipuliferum (Oct 2023).
This plant and Den. tipuliferum (synonym Diplocaulobium tipuliferum) have very distinctive lip form, lip margins and markings, especially in the throat. It is an excellent match to photos in the OW, IOSPE, orchidroots, Woods, "The Dendrobiums" and Laverack et. al., "Dendrobiums and their Relatives".

Dendrobium-fuscifaucium-Ashwin-CHM/AOS-2023-08-11 *SITF confirms that this plant is Dendrobium fuscifaucium (Aug 2023).
This plant matches the very good photo, several illustrations and description of Dendrobium fuscifaucium; found in novataxa.blogspot.com, "Species New to Science", May 2022. It as named for the chocolate disk on the lip. The species was originally found and described from a local nursery and supposedly was collected from the Kasi District in the Vientiane Province of Laos. It is similar to D. hekouense, D. luoi and wangliangii.

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

Three flowers and fourteen buds on three inflorescences to 2-cm on a nine growth plant 6.5-cm wide by 5.5-cm tall mounted on a 5-cm by 8-cm cork slab; pseudobulbs elongate to 3.5-cm long by 0.5-cm wid...
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".

Dendrobium-bilobum-Irene-CBR-(Provl)-20234879-2023-04-15 *SITF has confirmed this plant as Dendrobium bilobum (May 2023).
Although this Section of Dendrobium is poorly understood, the preponderance of characteristics places this plant within Dendrobium bilobum. Schlecter commented in the "Orchidacea of German New Guinea" that there is hardly any other section in which the distinguishing features of the species have presented such insuperable difficulties as this one. The most important characteristics in this Section seem to be the size of the leaves and their various parts, length and shape of the mentum, width of the petals and most importantly the shape of the lip. Schlechter also said that most of the individual species within Section Monanthos are inter-related and it is not easy to distinguish them. The leaves on this plant are a better fit to D. bilobum than to the closely allied species, D. erectifolium, which has much longer leaves than D. bilobum. This plant meets the description as detailed and illustrated in Lewis & Cribb's 1991 book, "Orchids of the Solomon Islands and Bougainville", although the flower size is large for D. bilobum.

Dendrobium-polyanthum-2023-03-26 *SITF confirms this plant is Dendrobium polyanthum (Apr 2023).
There is a large amount of confusion between D. polyanthum, D. primulinum and D. cretaceum. Kew in the POWO considers D. polyanthum and D. primulinum to be separate species, however, many sources lists them as synonymous and many of the photos (OW and orchidroots) has them lumped together as D. polyanthum. The IOSPE lists them as separate species. There is an exact match to this plant in the POWO as D. polyanthum. Kew considers D. cretaceum a synonym for D. polyanthum. H. P. Wood in "Dendrobiums" described D. polyanthum and states,: "Discussions about the legitimate name of all three (polyanthum, primulinum, and cretaceum) go back more than a century." Wood stated he studied the type specimens at Kew and agreed with Kew that the correct name is D. polyanthum.

Plant was entered in the show as Dendrobium primulinum. The judging team thought this was Dendrobium polyanthum instead, so this needs to be identified to be certain.
