SITF Submissions and Findings

The Species Identification Task Force receives submissions from orchid judging centers or exhibitors. The submissions are labeled by the name submitted under. When the plant's identity is confirmed, the last line in the post will have the correct name. We sometimes update pages with reference material pertinent to the submission.

Catasetum-ivaneae-2024-03-14 *SITF confirms that this plant is Catasetum ivaneae (Mar 2024).

This plant is an excellent match to the photo of Ctsm. ivaneae in the article by Fred Clarke in the 2020 Supplement to the AOS "Orchids" magazine. The same photo appears in the OW and some photos in orchidroots.com are similar. The species is very distinctive in the genus and is endemic to Brazil (Amazonas, Rondonia). It was very recently described in 2016 in Orquidario Vol. 30.

Paph-appletonianum-2024-03-12 *SITF has determined this plant to be Paphiopedilum appletoniaum var. cerveranum (Apr 2024).

This plant matches the description of Paph. appletonianum var. cerveranum. P. appletonianum var. appletonianum has a staminode that is a classically shaped inverted horseshoe; P. appletonium var. cerceranum has a staminode which is shallower, a little more broadly shaped with a sharply pointed extension in the middle on the bottom. It is very similar to P. appletonium var. cerveranum, Award #20243709, which was previously confirmed by SITF. Variety cerveranum is a validly published subspecies of P. appletonianum.

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.

Paphiopedilum-robinsonianum-2024-02-19 *SITF has determined this plant to be Paphiopedilum appletonianum var. cerveranum, not Paphiopedilum robinsonianum (Mar 2024).

Paph. robinsonianum belongs to a group of species that includes Paph. volonteanum and has a unique fluted staminode dorsal surface that does not look like this flower. The illustration and photo of Paph. robinsonianum also show the staminode overtop of the infolds of the pouch, not behind. The staminode of this plant matches Paph. appletonianum, as does the nobby structure and markings on the infolds of the pouch. Several photos of Paph. appletonianum var. cerveranum shown in the orchidroots.com and the image of a dried specimen in Kew's POWO is a close match to this flower. Kew considers P. appletonianum var. cerveranum to be synonymous with P. appletonianum; however, it is a validly published taxon in the Orchid Atlas in 2007.
