Pleurothallis

Finding

SITF confirms this plant is Pleurothallis gracilicolumna (Apr 2025). Mark Wilson, the describing taxonomist for this species, has advised that this plant is P. gracilicolumna, not P. talpinaria. At first glance, P. gracilicolumna and P. talpinaria are superficially similar; however, the lip midlobes are completely different. P. talpinaria has three nearly equal teeth and three ridges that run from the base of the lip to the very tip of the teeth; whereas this plant has unequal teeth at the apex with the mid tooth narrower and shorter than the outer teeth.
