Lepanthes-pictilis-2023-06-01 *SITF confirms this plant as Lepanthes pictilis (Jun 2023).

Confirmation based on the Luer and Hirtz drawing in the IOSPE and the description in Vol. 30(1) 2009 Selbyana, "Miscellaneous New Species in the Pleurothallidinae" by Luer. This matches the caespitose habit, the inflorescence originating from behind the leaf and the approximate size and color of the flower. There is a single vein that shows in each of the lateral sepals that match the drawing and the flower form is almost exact. A matching photo of L. pictilis by Garrit Verhellen may be found on the Orchid Forum.

Phragmipedium-wallisii-2023-05-23 *SITF has determined this plant to be Phragmipedium humboldtii, not P. wallisii (May 2023).

Phragmipedium wallisii is now considered a synomym for P. warszewiczianum, however, this plant does not match the description of P. warszewiczianum; The flower color, plant habit, and staminode shape matches P. humboldtii, as seen in the IOSPE. The longer petal length also supports this as P. humboldtii. Lindleyana article (2011) by Dressler & Pupulin has photos for comparison and a key to P. humboldtii.

Myrmecophila-grandiflora-2023-05-22 *SITF confirms this plant as Myrmecophila grandiflora (Jun 2023).

The color of the flowers in the photos was not accurately captured; the color on the distal portions of the segments was described as being much more suffused with brown, instead of the bright red shown. There is photo by Grobler which shows this brownish coloration in the OW. M. grandiflora is a giant among the Genus; this is a large plant meeting the description of an enormous species; flower form appears correct, as does the yellow callus that runs the length of the midlobe. Flower size is also large at 7.2 cm. Many supporting photos can be found in the orchichroots.com and the IOSPE and other on-line sources.

Bulbophyllum-graveolens-2023-05-21 *SITF has confirmed this plant as Bulbophyllum graveolens (May 2023).

An award was given to B. graveolens with a spotted dorsal sepal by the AOC and several photos in orchidroots.com show spotted dorsals with the name B. graveolens var. robustum, which is not recognized by Kew. Kew does recognize Cirrhopetulum robustum as a synonym for B. graveolens. The "Orchids of New Guinea" website also pictures examples of a spotted form where the spotting is carried out onto the lip.

Lepanthes-leporina-2023-05-19 *SITF Confirmed this plant as Lepanthes leporina May 2023).

The drawing and lineup of species in the L. guatemalensis group match this plant only to P. leporina. "Illustrations and Studies in Neotropical Orchidaceae. 6. The Lepanthes guatemalensis group in Costa Rica" by Bogarin and Pupulin show a photo of L. leporina that clearly matches this plant. The IOSPE photo also closely matches this plant.

Peristylus-parishii-2023-05-15 *SITF confirms this plant as Peristylus parishii (May 2023).

Confirmation based on the tri-lobed lip and horizontally held tubular-like petals; excellent match to the photo on the IOSPE, the photos in orchidroots.com and to the illustration in Lucksom's 2007 " The Orchids of Sikkim and NE Himalaya". This plant matches the flower size and number of flowers per inflorescence for P. parishii.

Barbosella-orbicularis-2023-05-11 *SITF confirms this plant is Barbosella orbicularis (May 2023).

The flower size is correct at .3 cm and the leaves are sub-orbicular, which matches the description for this species. The article, "New Species and Records of Orchidaceae from Costa Rica" in Lankesteriana by Bogarin, Karremans & Pupulin contain the description and drawing of B. orbicularis which matches this plant. The species is easily recognized by its creeping habit and rounded, smooth, overlapping leaves and tri-lobed lip; in the Award Description, the judges described the lip as having two structures, which they termed "incurved lobules", which could be interpreted as keels. Supporting matching photos may be found in the IOSPE, OW and orchidroots.com.

Plant acquired from Ecuagenera. Sorry about the very poor quality of the dissected photo. The very tiny, fragile flower just fell apart.

Dracula-erythrochaete-Blanca-CHM/AOS-2023-05-06 *SITF confirms this that plant is Dracula erythrochaete (Aug 2023).

This plant almost exactly matches the specimen from Kew's herbarium shown in the POWO. The plant and flower matches Luer's description and drawing in his Dracula Icones including three keels on the lip lobe and denticulate margin and it also matches the photo in the IOSPE.

Ophrys-sphegodes-subsp-aesculapii-Yellow-Petticoats-CHM/AOS-2023-05-03 *SITF confirms this plant as Ophrys sphegodes subsp. aesculapii (May 2023).

Ophrys sphegodes and Ophrys aesculapii were considered separate species in the 2006 Pierre Delforge's "Orchids of Europe, North Africa and the Middle East". The photo of O. aesculapii is a close match to this plant; however, Kew now considers aesculapii a valid subsp. of O. sphegodes. The genetics in this group are unclear, but most taxons appear genetically to be subspecies. Flower size and available images of O. sphegodes subsp. aesculapii closely match this plant. The mask pattern on the lip appears somewhat variable.
