Galeandra minax 'XTK' CHM 2024-05-10
Posted on May 10, 2024
Finding
SITF confirms this plant as Galeandra minax (May 2024). There is an excellent matching photo of Galeandra minax in the POWO and twelve closely matching photos in the orchidroots.com. The flower size appears a little smaller (3.8 cm Vert. vs. 4.2 cm) than is described in the IOSPE. There is also a description of G. minax by Wilson and Wilson and a photo by Marni Turkel in an article in the "Orchids" magazine, June 2023.
Pinalia eriopsidobulbon 'Lori Lyon' CBR-2024-05-10

Paphiopedilum rothschildianum 'Krull's Dark Chocolate' AM-2024-05-06
Posted on May 06, 2024
Finding
SITF confirms this plant as Paphiopedilum rothschildianum (May 2024). This plant was entered as a primary hybrid of Paph. rothschildianum, however, the judging team believed it might be a straight Paph. rothschildianum. SITF concurs based on the numerous white cilia on the surface of the staminode which mimics aphids that attract predator wasps, its primary pollinators. This is a recessive trait and a key characteristic of Paph. rothschildianum. Measurements of the flowers also agree better than as a hybrid. A primary hybrid with P. gardineri would reduce the overall stature of the flower and plant.
Phalaenopsis tetraspis 'The Orchid Den' AM-2024-05-04

Calanthe-judithiae-2024-04-21
Posted on April 21, 2024
Finding
The flower of Calanthe judithiae does not match the form of the lip of this plant. This plant is an exact match to the 2020 AOS awarded Calanthe leonidii, #20204471/CHM. The flower form and color, including the golden yellow protuberances at the base of the lip, matches this plant, as does the flower size given in the IOSPE description. This plant also matches the photos found in the Vietnamese article: http:/hoalanvietnam.org/6B2_lv/3hk/Kieu-Lan-leonidii.pdf .

Bulbophyllum-sterile-2024-04-09
Posted on April 09, 2024
Finding
The petals of B. sterile are broadly triangular, as are these and the trilobed lip has the cleft middle lobe and two acute lobes that are visible in this flower. The pseudobulbs on this plant match the description in the "Flowers of India" website as conical-ovoid, faintly four-angled; there is also a photo matching this plant in the "Flowers of India" and matching photos of B. sterile in the "eFlora of India" website. This flower closely matches the photo of B. sterile (as B. neilgherrense) in the IOSPE and Seidenfaden & Smitinand's 1959, "The Orchids of Thailand" stated that B. sterile can be distinguished by its distinctive membraneous bracts, reddish-brown stripes in the sepals, acute triangular lateral sepals, acute and short vertical horns on the column and the lip with basal auricles.

Cattleya loddigesii 2024-04-01
Posted on April 01, 2024
Finding
SITF has determined this plant to be Cattleya loddigesii (Jun 2024). Neither C. loddigesii nor C. harrisoniana can be separately identified with absolute certainty. This plant matches the description of C. loddigesii in Withner's "The Cattleyas and their Relatives, Vol. 1"; however, as Withner states, C. harrisoniana was considered a long-time variety of C. loddigesii. It was most certain to have been crossed and back-crossed many times between the two when they were considered the same species and registered as C. loddigesii. The two species also overlap in their habitats and form natural hybrids, which with back-crosses also has led to introgression between the two species. This plant is very similar to the awarded loddigesii #20141868, confirmed by SITF in May 2014 and, as does the previous award, has some similar traits of C. harrisoniana.
Dendrobium lituiflorum 2024-03-31
Posted on March 31, 2024
Dossinia marmorata 2024-03-29
Posted on March 29, 2024
Finding
SITF confirms this plant as Dossinia marmorata (C. Morren) (May 2024) without a type (form) designation. There is no taxonomic standing for the putative "Dayii" form. The leaves are not as dark green, but more olive. There are fewer reticulations and they are pinkish rather than silver. This is a classic form of D. marmorata, as illustrated in photos of the plant and flowers in the IOSPE. There are also 17 images of Dossinia marmorata in the orchidroots.com that match this plant in both leaves and flowers.
