Abstract

A blackish brown color is a feature of the mycoheterotrophic orchid Gastrodia pubilabiata. Here, we report a new form of G. pubilabiata with a tinge of red color. A total of ten plants showed a reddish plant body, and this phenotype seems to be stable in two localities. Based on analyses of plant morphology, distribution and pigment, together with color identification using the Munsell color order system, we describe the reddish plants as G. pubilabiata f. castanea.
