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.

Dendrobium-luzonense-2023-02-18 *SITF confirms this plant is Dendrobium luzonense (Apr 2023).

This plant is a good match in both form and color and the distinctive markings on the lip and column on an otherwise concolor flower; plant and flower measurements closely fit the description; plant is an excellent match to the original detailed description and drawing of D. luzonense in the Taiwania Journal published in 2007; good supporting photos may be found in several sources, including the IOSPE and OW; flower color is somewhat variable.
