Dendrobium-arachnoideum-2023-08-06 *SITF confirms that this plant is Dendrobium arachnoideum (Aug 2023).

This plant is an excellent match to the description and photo in Laverack et. al. "Dendrobiums and its Relatives". Also, a good match with D. arachnoideum in the OW, orchidroots and in the IOSPE as Diplocaulobium arachnoideum. Also described with photos in the http://www.orchidsnewguinea.com website.

Pinalia-rhodoptera-2023-08-05 *SITF confirms that this plant is Pinalia rhodoptera (Aug 2023).

This plant is an excellent match to the description and photo in Cootes's 1991, "Orchids of the Philippines" and the illustration in the OW and photos in the orchidroots.com. It also matches the photo in the IOSPE as Eria rhodoptera.

Telipogon-astroglossus-Fiona-CHM/AOS-2023-07-27 *SITF confirms this plant is Telipogon astroglossus (Aug 2023).

This plant matches the photo in the IOSPE and the description in Dodson's "Native Ecuadorian Orchids". Also closely matches 18 photos in the orchidroots.com. The description of this plant indicates measurements of the pseudobulb; however, Dodson describes the species as pseudobulbless; this could due to mistaking the conduplicate leaf bases for a cane or pseudobulb. No pseudobulbs appear visible in the photos. Flowers are somewhat large at .96 cm compared to the description in the IOSPE of .65 cm.

Paphiopedilum-leucochilum-var-album-2023-07-26 *SITF has determined this plant to be Paphiopedilum leucochilum (Yellow Form) (Aug 2023).

The true Paph. leucochilum has a clear white pouch without spots, for which the species was named. The sepals and petals on this flower is a pale cream-yellow with a lighter-to-white pouch devoid of spots, as can be seen in the photos. The award sheet states the dorsal sepal is "veined faint burgundy, almost imperceptible" with "petals spotted faint burgundy". This is difficult to see on the photos, since the burgundy is very faint, but it is there and this would negate an "album form". Also, there are no validly published subspecies, including variety album, for this species. The yellow form of P. leucochilum seems very rare and there were none found in the available images of P. leucochilum.

Maxillaria-tenuifolia-2023-07-24 *SITF confirms that this plant is Maxillaria tenuifolia (Aug 2023).

This plant appears to be a large, very vigorous growing Maxillaria tenuifolia. The hybrid Max. Maui Coconut (M. tenuifolia x M. sanguinea) was considered; however, M. tenuifolia is much larger than M. sanguinea, which has smaller, thinner leaves. The hybrid is also smaller than M. tenuifolia and this plant. It's possible this plant could be line bred to produce larger flowers with better substance and may possibily even be polyploid and still within the variability of M. tenuifolia.

Platystele-umbellata-2023-07-24 *SITF confirms this plant as Platystele umbellata (Yellow Form) (Jul 2023).

This species is very distinctive with its umbel shaped inflorescence for which it is named. Previous awards to this species and all available photos show flowers that are only purple to bright red, this plant is an unusual deep old gold-yellow color. This plant matches the Type drawing by Ortiz in the IOSPE, including the minute cilia on the flower when the photos are greatly enlarged.

Porpax-extinctoria-2023-07-17 *SITF confirms that this plant is Porpax extinctoria (Dec 2023).

This plant was identified as Porpax extinctoria by Dr Henrik Aerenlund Pedersen, the co-author describing this species along with Andre Schuiteman and Y. P. Ng. Porpax extinctoria and P. summerhasiana are very similar; however, the "shriveled" pseudobulbs of this plant better match P. extinctoria than P. summerhasiana as shown in the IOSPE plant and flower photo. The gold-yellow keels on the lip also match P. extinctoria as can be seen in the image showing the lip. Twenty matching photos can also be found on the orchidroots.com.

Encyclia-x-darieniana-Memoria-Konstanty-Maciaszek-CHM/AOS-2023-07-15 *SITF confirms this plant as Encyclia x-darieniana (Jul 2023).

This plant was identified by one of the describing taxonomists, Ruben Sauleda, as definitely E. x darieniana. It matches the description and photos in the New World Orchidaceae 2019 paper "Nomenclatural Notes A New Natural Hybrid of Encyclia moebusii H. Dietr. (Orchidaceae) is Described for Cuba" by Davila, Esperon, and Sauleda. This plant fits the intermediate form between E. moebusii and E. phoenicea.

Dendrobium-sinominutiflorum-Little-Green-Gem-2023-07-13 *SITF has determined this plant to be Dendrobium compactum, not Den. sinominutiflorum (Aug 2023).

Plant identification aided by Andre Schuiteman. Den. sinominutiflorum has lip side lobe apices sharply dentate and margins entire or margins inconspicuously notched; the lip has three keels which merge to form a broadly thickened fleshy ridge. These characteristics are not seen on this plant. This plant matches the photo of Den. compactum in the OW and Baker and Baker's description of Den. compactum in "Orchid Species Culture: Dendrobiums". The flower size and color also match Den. compactum.
