  • Discussion

    One specimen is suggestive of a hybrid C. officinalis X pubescens. It combines the narrow, chartaceous leaf blades, with somewhat poorly developed pit domatia, of the former species, with the hirtellous leaf indumentum of the latter. Both parental species are known from the immediate vicinity.
