Dendrobium-ramosii-2022-10-18 *SITF has confirmed this plant as Dendrobium ramosii (Jan 2023); based on the finely toothed, simple lip and the ovary and segment shapes and sizes, as well as the leaf and cane size described with photos in Cootes' "Orchid of the Philippines" and the description in Baker & Baker's, Dendrobium Orchid Species Culture"; matches photos in the IOSPE, OW and orchidroots.com; there are apparently two color variations (pink and coerulea); flower size is on the small size of the range.*

Dendrobium ramosii Ames, Philipp. J. Sci., C 7: 18 (1912). This name is accepted.

Bulbophyllum-aeolium-2022-10-17 *SITF confirms that this plant is Bulbophyllum aeolium (Feb 2023); POWO lists two forms for B. aeolium: subsp. aeolium (syn. B. sociale  and B. uniflorum) and subsp. padasense; this is the multiflowered B. aeolium subsp. aeolium (syn. sociale); correct based on characteristics in the description in Comber's "Orchids of Sumatra" of having a short column with short, rounded stelids; supporting photos may be found in the OW and several other on-line sources.*

Rhomboda-moulmeinensis-2022-10-12 *SITF determined this plant to be Rhomboda fanjingensis, not Rhomboda moulmeinensis (Nov 2022); the origin of this plant was in China; the key difference between the two species is in the epichile; R.  moulmeinensis has more or less rectangular lobes with denticulation on the apexes; R. fanjingensis has an epichile that is subquadrate with rounded apexes and no denticulation as is this plant; the leaves also match that of the pressed plant in Kew's Plants of the World-Online; there is a good image in https://en.wikipedia.org/wiki/Rhomboda that clearly shows the epichile of R. moulmeinensis.*

Cattleya-nevesiana-2022-09-30

Posted on Sep 30, 2022

Fusiform pseudobulbs are 5 cm long x 1 cm diameter. Unifoliate caniculate leaves are 7 cm long x 1.5 cm wide. 9 tightly clustered pseudobulbs with short rhizomes in a 7 cm square plastic pot.

Cynorkis-purpurea-Bryon-CBR-2022-09-24***SITF has determined this to be Cynorkis purpurascens, not Cynorkis purpurea (Sep 2022); Plant does not match the IOSPE photos or Kew's Plants of the World On-Line; these lateral sepals are almost circular without the acute apices found on C. purpurea; C purpurea has 4 to 5 leaves which lay flat against the media; C. purpurascens has a single leaf purpendicular to the ground; flower form, size and photos more closely fit C. purpuracscens.***

CHALLENGE-to-Phragmipedium-longifolium-var-longifolium-(Album)-2022-09-23***SITF confirmed as Phragmipedium longifolium var. longifolium (Sep 2022);

This plant matches the album form of P. longifolium var. longifolium; the challenge was issued based on undulations of the petal margins; however nearly all P. longifoliums have undulations of the petal margins to varying extents and, therefore, are not contraindicative of this plant being the correct species;  one of the photos of this plant show auricles raised above the pouch tissue which is a characteristic of the species; this plant closely matches the P. longifolium f. album in Guido Braem's book, "The Genus Phragmipedium".***

This award was posted in July on Facebook right after being awarded. I immediately received a challenge to it, as not a species and most likely Phrag. Praying Mantis based on the crisping (undulation)...

CHALLENGE--Bulbophyllum-Wilbur-Chang-2022-09-21 *SITF determined this plant to be Bulbophyllum Jersey, not Bulbophyllum Wilbur Chang (Sep 2022); based on the form of the flower and differences in the lips as shown in comparison photos in the OW; Bussey's close-up photo of the lip of B. Jersey compared to Grobler's close-up photo of B. Wilbur Chang in the OW clearly show this plant to more closely match B. Jersey than B. Wilbur Chang; the wider falcate lateral sepals also more clearly match B. Jersey than B. Wilbur Chang.*

This award was published and questioned by a student judge. In reviewing it, the student is correct that this flower does not exhibit the correct characteristics for Bulb. Wilbur Chang. My initial imp...
