Bulbophyllum-obliquum-2023-02-05 *SITF confirms this plant as Bulbophyllum obliquum (Jun 2023).
Bulbophyllum trifilum flowers are very similar to B. obliquum; however B. trifilum does not match in plant form, on inflorescence length, leaf shape, the number of flowers per inflorescence or in flower size. The leaves of B. obliquum and this plant are flattened, oblanceolate and the rhizomes are long and floral bracts acute. The leaves of B. trifilum are terete. Supporting photos may be seen in the IOSPE.

Microsaccus-wenzelii-Pixie-Dust-2023-02-01 *SITF confirms this plant is Microsaccus wenzelii (Jul 2023).
This is the closest match of the twelve known species in the genus; the flower size matches at 0.8 cm. This plant matches the photo in the IOSPE and is a very close match to the seven photos in the orchidroots.com. This plant matches the description in the IOSPE and OW of being a miniature plant with 2-ranked (distichous), flattened leaves with a single flower on a short, axillary inflorescence.

Coelogyne edii Syn Pholidota sulcata 2023-01-22 *SITF confirms this plant is Coelogyne edii (Apr 2023).
Coelogyne edii (Synonym Pholidota sulcata) matches the description and photos in the IOSPE, OW, (As Pholidota sulcata) and orchidroots; IOSPE has a very good close-up photo of the species flower and a photo of the plant that is a very good match to this submission; the five-nerved leaves also fit the description of C. edii.

Oberonia-costeriana-‘Irene’-Syn-Oberonia-obesa-CBR(Prov’l)-NEJC-NJ-21Jan23-2023-01-22 *Based on new information, SITF has re-determined this plant to be Oberonia cylindrica, not Oberonia mucronata (Aug 2023).
Dr. Daniel Geiger, the globally recognized authority in the Genus Oberonia, has reassessed this plant and now identifies it as Oberonia cylindrica. He also stated these two species are similiar and in the future O. cylindrica could possibly become a subspecies under O. mucronata.

Ornithocephalus-gladiatus-2023-01-17 *SITF has determined that this plant is Ornithocephalus dolabratus, not Ornithocephalus gladiatus (Jul 2023).
This plant does not match the drawing by Hooker in 1824, the apiculations on the apices of the sepals and petals are much longer than shown in the drawing. The form of O. dolabratus fits this flower better than O gladiatus, especially the dorsal sepal. The lateral sepals appear connated all the way to a long, apiculated apex, where the lateral sepals on O. gladiatus are spread and the long spur like extension at the apex of the lip matches O. dolabratus as can be seen in the IOSPE photo. Other matching photos can be found in the OW and Pinterest.

Oncidium-lucianianum-2023-01-06 *SITF confirms this plant as Oncidium lucianianum (May 2023).
This is correct based on the description in Baker and Baker's 2006 "Orchid Species Culture: Oncidium/Odontoglossum Allaince" under the old synonym Odontoglossum lucianianum; this species has two keels covered with soft hairs and a column with a pair of wings in the form of slender, sharply pointed, fingerlike projections that emerge near the stigma. Matches illustration in Chase et. al. 1997, "The Pictorial Encyclopedia of Oncidium" (also as Odont. lucianianum) and to photos in the OW.

Polystachya-lawrenceana-2023-01-03 *SITF confirms that this plant is Polystachya lawrenceana (Jul 2023).
This species can be recognized by the brush-cut, rectangular patch of short bristles in the lip throat. The resolution and soft focus of these photos do not produce images sharp enough to see these bristles in detail, and although they can't be resolved, they can be barely seen in one photo. A similar species, P. zambesiaca is described as having a sharply pointed midlobe apex, wheras P. lawrenceana has a broadly blunted, bilobed midlobe apex. In the description of P. zambesiaca, it is pointed out that this species is variable and there are often intermediate forms which make it difficult to draw a dividing line. In many of the available photos of either species, the lip apices may be seen that are sharply pointed or bilobed.
