Petals whitish-green and distinctly paler than sepals. Lip 8mm x 3mm with rounded-dilated base. Spur cylindric, 8mm. Wings reflexed, 6-7mm. Column 2.5mm x 1.75mm; hood 5mm x 3.75mm. Anthers nearly parallel and upright. Pollinia gone. Growing within a few meters of M Pollock 449, and compared with that specimen has larger flowers that are slightly more fragrant, whiter petals, and more nearly parallel anthers with evidence of self-pollination not observed, but overall very similar and likely the same species. The newer, barely opened flowers near the top of the inflorescence are somewhat more similar in color, size, and shape to M Pollock 449 (i.e. smaller, greener, less vertical anthers, less rounded base on lip)..
