Malaxis-crispifolia-2022-12-19 SITF has determined this plant to be Malaxis excavata, not Malaxis crispifolia (Dec 2022); the name crispifolia implies crisped foliage, but there is no evidence of this in the photos, also the lip is distinctly tri-dentate apically, but the drawings of M. crispifolia in the "Orchids of Venezuela Field Guide" does not show this; this plant keys to Malaxis excavata in the Key to Malaxis in Dressler's 1993 "Field Guide to the Orchids of Costa Rica and Panama"; photos in the orchidroots.com are a close match between this plant and M. excavata.

Maxillaria-mapiriensis-2022-12-19 *SITF confirms this plant as Maxillaria mapiriensis (May 2023).

These flowers are somewhat larger than those described in "Orchidacearum Peruvianum", but it superficially fits the description; there is a notch in the lower edge of the column and acute side lobes which also match the description. Christenson's Monograph, Vol. 2 has a photo of the vegetative growth of M. mapiriensis that is an excellent match to this plant and the illustration in Vol. H-O of Dunsterville & Garay's, "Orchids of Venezuela" matches this flower as well. Matching photos can be found in the OW and in the IOSPE's (Another Color Form).

Dendrobium-merrillii-2022-12-14 *SITF confirms this plant as Dendrobium merrillii (Jun 2023).

Vegetatively this Section Aporum Dendrobium matches the dried specimen in the POWO. Color matches the description of milky white flower with purple markings on the side lobes and the size is within range. It is correct based on the description in Baker and Baker indicating a three-lobed lip with a small rounded midlobe and obscure, hairy side-lobes. Leaves are slightly imbricated and alternate up the inflorescence; the growth habit matches Baker and Baker. This plant also matches the description and excellent photographs of Dendrobium merrillii in the Monaco Nature Encyclopedia.

Bulbophyllum-tricornoides-2022-12-11 *SITF confirms this plant is Bulbophyllum tricornoides (Apr 2023).

This plant was previously identified by Leslie Garay as B. tricornoides; the combination of very long, forward-pointing carinae at the apex of the column and lip without ridges fit this species; B. tricornoides and B. tricorne are very similar, the difference in characteristics are the teeth of B. tricorne are short, blunt and sharply downturned; the teeth of B. tricornoides are long, sharply pointed and extend straight out from the apex of the column; this plant fits the characteristics of B. tricornoides; there is an almost identical photo to this plant in the IOSPE.
