Bulbophyllum-kubahense-2023-10-01 *SITF confirms this plant is Bulbophyllum kubahense (Oct 2023).

Bulbophyllum kubahense is closely related to B. refractilingue. B. kubahense appears to have flowers with segments more rounded, obtuse at the apices, where B. refractilingue appears to have flowers more pointed on the apices when compared to the photos. Also, based on flower size, with B. kubahense measuring 2.5 cm vs. less than two for B. refractilingue, this flower matches B. kubahense measuring 2.8/2.6 cm. Dr. J.J. Vermuelen, the "Orchids of Borneo Vol 2" describes B. refractilingue as having well defined teeth along the lower margins of the column; however, there is no evidence of these in this plant which appears to have a smooth margin. Both species have very well defined downswept thick horns like this plant.

Chytroglossa-marileoniae-2023-10-01 *SITF confirms this plant is Chytroglossa marileoniae (Oct 2023).

There are three species in this Genus: C. aurata, C. marileoniae and C. paulensis. The only other similar species is C. aurata, but the inflorescence of C. aurata is too long at 15 cm, where the inflorescence on this plant measured 4.5 cm and C. marileoniae is described as having an inflorescence of 5 cm. This plant has on average 4.6 flowers per inflorescence and C. marileoniae has 4-6 flowers per inflorescence and C. aurata has 10 flowers per inflorescence. This plant also matches the previous AOS/CHM awarded plant and Baker's description in the OW. The species is endemic to S.E. Brazil.

Maxillaria-cucullata-2023-09-29 *SITF confirms this plant is Maxillaria cucullata (Dec 2023).

The form of this flower is a good fit to Maxillaria cucullata. The Feb-Mar 2018 Australian Orchid Review article on Maxillaria by David Banks shows photos of this species which match this plant. The article states M. cucullata is a highly variable species with a degree of darker markings ranging from fine pepper spotting to larger spots. The lip can vary from tan to dark brown to almost black. These flowers had dark spots on the sepals and petals with a dark brown lip. Flower size can vary from 4 to 9 cm; this flower measured 4.5 cm N.S. This plant has large, cupped bracts slightly longer than the ovaries and which partially cover the basal portion of the flower which fits the description of M. cucullata in Eric Christenson's Unfinished Monograph on Maxillaria; however, Christenson also stated that the species had no markings on the flowers.

Habenaria-macroceratitis-2023-09-05 *SITF confirms this plant is Habenaria macroceratitis (Sep 2023).

Confirmation is based on the description in McVaugh's 1985 "Flora Novo-Galiciana" (Vol. 160) which delineates the difference between this species and H. quinqueseta. The key characteristic is the difference between the upper and lower lobes of the petals with H. macroceratitis being greater than H. quinqueseta in the lower lobe, as seen in this plant. Also, this plant matches the description and key in Brown's 2002 "Wild Orchids of Florida". It is close match to Subrahmanyam's photo in the IOSPE and photos in the orchidroots.com.

Prosthechea-joaquingarciana-Rita-Emilia-CBR/AOS-2023-08-25 *SITF confirms this plant is Prosthechea joaquingarciana (Oct 2023).

This plant matches the description and photo of P. joaquingarciana in the IOSPE (as the synonym Anacheilum joaquingarcianum) and Pupulin's original description in Selbyana 22(1):19. 2001; a photo and drawing can be found in https://epidendra.com/. It is similar to P. radiata, but P. joaquingarciana has linear, subterete, sulcate pseudobulbs and spots on the segments with a widely ovate lip as does this plant. The pseudobulbs of this plant measure 25 cm, which is in range and the flower size also meets the description. This plant had many blooms on a two-leafed pseudobulb, which eliminates the 2-flowered P. baculus and P. baculibulbum, which has 3-leaves.

Lepanthes-inescata-Yilary-CBR/AOS-2023-08-25 *SITF confirms that this plant is Lepanthes inescata (Aug 2023).

Plant was identified by Dr. Franco Pupulin as L. inescata. The photo of L. inescata in the IOSPE is a close match to this flower, although the leaf shape in the IOSPE photo is a wider cordate shape and the leaf on this plant is more narrowly cordate; however, this may be an artifact of photography.

Dracula-saulii-2023-08-24 *SITF confirms that this plant is Dracula saulii (Aug 2023).

This plant exactly matches the description and findings of Dracula saulii 02-14-2023, award number 20234261. The key characteristic of D. saulii, besides the velutinous hairs covering the flower, is the unusual length of the dorsal cauda compared to the lateral caudae; in D. saulii, the dorsal tail is two to three times shorter than the length of the lateral tails. In this flower the dorsal sepal cauda is 4.2 cm and the lateral sepal caudae is 11.5 cm. D. saulii is also distinguished by its small size and narrowly linear, obtuse leaves. The only other species that appears close is D. adrianae, but all the caudae on D. adrianae are about the same length and it differs in its plant characteristics. This plant displays distinctive, reflexed segments and dense spicules on the surfaces of the segments as does D. saulii.
