Cattleya-cardimii-2023-08-20 *SITF has determined this plant to be Cattleya bradei, not Cattleya cardimii (Aug 2023).

Withner describes C. cardimii with a photo (as Laelia cardimii) in his series "The Cattleyas and their Relatives Vol. 2-The Laelias". It carries three pale yellow flowers on a relatively tall, thin inflorescence with nearly 12 cm to the first flower. Cattleya bradei carries two to four flowers on much shorter inflorescences than C. cardimii on smaller plants like the plant in this submission. This is an excellent match to photos in the IOSPE, OW, orchidroots and the Withner book.

Cattleya-mendelii-2023-08-07 *SITF confirms that this plant is Cattleya mendelii (Aug 2023).

The pseudobulbs are ribbed and more or less cylindrical; photos show a single leathery leaf, which is held nearly vertical and the lip markings fit the description and the photo in the IOSPE. This is a good match to many of the "semi-alba, coerulea" forms of C. mendelii shown in the orchidroots.com.

C-nobilior-alba-2023-06-07 *SITF confirms that this plant is Cattleya nobilior f. alba (Jul 2023).

This plant is an alba form of Cattleya nobilior, which is a validly published subspecies in Orquidologia Sul-America (2004); it matches the key characteristics of having full side lobes which close over the column and extend to the full length of the column and bifoliate leaves which separates this species from Cattleya walkeriana, which is rarely bifoliate. A very good matching photo of Cattleya nobilior f. alba (Joe Panozo) can be seen in the IOSPE.

Cattleya-lawrenceana-f-albescens-2023-05-02 *SITF confirms this plant as Cattleya lawrenceana (May 2023).

This plant matches the description of Cattleya lawrenceana; shape of the lip of C. lawrenceana is very distinctive. There is no published taxonomic description to subspecies of C. lawrenceana for the albescens color, so f. albescens cannot be used in this case. This is an uncommon, lightly colored form of C. lawrenceana. This plant may be a line-bred color mutation that came out of Chadwick's stock.

Cattleya-nevesiana-2022-09-30 *SITF has determined this plant to be Cattleya bradei, not C. nevesiana (Aug 2023).

Plant identification was aided by Francisco Miranda, a noted Brazilian taxonomist, who identified this plant as a "textbook Cattleya bradei". Cattleya nevesiana shows an elongate inflorescence with flowers laxly arranged and a lip with a triangular extension at the end of the midlobe and none of the crisping of the margin as in this flower. The form of this flower is fuller and rounder than C. nevesiana and more closely matches C. bradei.
