Morphological variation in the Species of Cephalanthera (Orchidaceae) in Japan Morphological variation in the Species of Cephalanthera (Orchidaceae) in Japan HAYAKAWA, Hiroshi Yamazaki, Jun KONUMA, Akihiro Yokoyama, Jun metadata only access Japanese Society for Plant Systematics Flower Lip Peloria Radial symmetry Zygomorphic Flower Lip Peloria Radial symmetry Zygomorphic We report four examples of morphological variation in the species of Cephalanthera (Orchidaceae) in Japan. We recognized a new peloric form, C. subaphylla Miyabe & Kudo f. conformis Hiros. Hayak. The new form has a tepal-like lip morphology. We also report variegation mutants of C. erecta (Thunb.) Blume var. erecta, which are albino-like in appearance. The above-ground parts of the mutants were withered at the immature seed stage during the end of June. We also observed variegated individuals of C. falcata (Thunb.) Blume f. falcata and C. falcata f. albescens S. Kobay. Finally, we discovered individuals of C. falcata f. falcata with a malformed flower at the top of an inflorescence with normal flowers in other parts of the same inflorescence from two localities. 日本植物分類学会, Japanese Society for Plant Systematics 2016-12 eng journal article https://repository.naro.go.jp/records/312 10.18942/apg.201605 SC10201707070020 https://dx.doi.org/10.18942/apg.201605 Acta Phytotaxonomica et Geobotanica 1346-7565 Acta Phytotaxonomica et Geobotanica Acta phytotaxonomica et geobotanica : APG 67 3 199 203
