Geranium yunnanense shares blackish anthers and fruit nodding when immature with G. refractum, G. sinense, G. delavayi, and G. pogonanthum. However, it has longer and not reflexed petals with abundant trichomes. Other important characters of this species are its broad bracteoles and its staminal filaments with long abundant trichomes.
