Vanilla martinezii Soto-Arenas

14.Vanilla martineziiSoto-Arenas (Soto-Arenas and Dressler 2010: 320) Fig. 2 E Type. GUATEMALA – Izabal • Livingston, El Golfete, a 20.4 km al NE de Río Dulce por lancha camino a Calix; 26 Jul. 2003; E. Martinez & D. Alvarez 36410; lectotype (designated here): MEXU! [MEXU 01478369]; isolectotypes: MEXU! [MEXU 01478370], AMO! [ESP 118178], BIGU not found, MO not found. Notes. Soto-Arenas and Dressler (2010) originally designated the specimen at MEXU as the holotype for Vanilla martinezii while identifying three isotypes located at AMO, BIGU, and MO. Upon examining the type collection at MEXU, we found two sheets under the same collector’s number, with no indication that they were part of a single preparation. Consequently, a lectotype designation is required. Here, we designate the sheet bearing a flower bud as the lectotype. Furthermore, after reviewing the AMO spirit collection, we identify a jar labelled “ E. Martinez s. n. ” with a single flower. Based on morphological congruence with the flower illustrated in the species’ original description (Soto-Arenas and Dressler 2010: fig. 10), we propose that this specimen most likely belongs to the original material used by Soto-Arenas. The illustration, as noted in the legend, is partially based on the type specimen (flower + dissection 1 + L-shaped column), E. Martinez 22790 (second column + dissection 2, including a petal, lateral sepal, and half of the lip), and M. Soto 8602 a (plant with fruits). It is likely that the flower preserved in the AMO spirit collection corresponds to the specimen Soto-Arenas referenced as “ iso. AMO! ” and we hereby designate it as an isolectotype. We could not locate the isotypes at BIGU and MO.
