Acianthera-cachensis-2023-08-22 *SITF has determined this plant to be Acianthera lepidota, not Acianthera cachensis (Nov 2023).
Identification was made with the assistance of Dr. Adam Karremans, the taxonomist of record for A. cachensis and a noted authority on Costa Rican Pleurothallids. Acianthera lepidota is from Costa Rica and Panama and is closely related to A. cachensis. Descriptions of these two species with photos are in Adam Karremans 2020 book "Pleurothallids Neotropical Jewels, Vol. 1". The purple veined leaves of A. lepidota and the flower form is a better match to this plant than is A. cachensis. A drawing and photo can also be found in the IOSPE, as Pleurothallis lepidota (a synonym).

Pleurothallis-(Acianthera)-boliviana-Bryon-CBR-2023-04-27 *SITF confirms this plant is Acianthera boliviana (Aug 2023)
This plant matches the description of Acianthera boliviana in Icones Pleurothallidinarum XXVI. Flower size at .4 cm is within range of the described (IOSPE) size of .5 cm and the photos are a close match. It matches the line drawing in the IOSPE of A. boliviana (as Pleurothallis boliviana). The flowers of A. boliviana and A. tricarinata are very simliar; but the bracts of A. tricarinata are larger and long enough to cover the entire ovary and extend well out onto the dorsal sepal; whereas, in A. boliviana and this flower, the bracts are much shorter and only partially cover the ovary. This plant also closely matches the flowers of A. boliviana in the OW.
