A comparative morphological survey based on herbarium specimens shows that two Chinese species of Veratrum, V. stenophyllum Diels and V. yunnanense O. Loes., are conspecific with V. shanense W. W. Sm. from Myanmar. The two Chinese species are, accordingly, reduced to V. shanense. Veratrum shanense as delimited here is distributed in M. E. Myanmar, and N.W. Yunnan, S.W. Sichuan and Guizhou, China. Lectotypes of both V. stenophyllum and V. yunnanense are designated. In V. shanense, infraspecific variations are found in some characters, such as perianth color, the size of tepals and bracts, and the pubescence of leaves, but no taxa appear to be clearly delimited. Veratrum stenophyllum var. taroense F. T. Wang & Z. H. Tsi with papillose-puberulent leaf veins is reduced to V. shanense. Veratrum shanense show andromonoecism and the bisexual flowers are strongly protandous. Morphological description, synonymy, bibliography, and some other information on this species are also provided. (85: 137-147)

A new species of Kaempferia L. (Zingiberaceae) from Central Thailand, K.lopburiensis, is described and illustrated. This new species belongs to the K. rotunda group (inflorescences on separated shoots arising from the rhizomes and appearing before pseudostems) and can be easily recognized by its 2-3 large orbicular leaves, red broadly-triangular and hairy ligules with obtuse or rounded apices, and rectangular or broadly obovate anther crests with tridentate to crenate apices. Relationship with its closely related taxon, K. grandifolia Saensouk & Jenjitt., is also discussed. (85: 148-152)

K.; cG. P. O. Box 9446, Kathmandu, NEPAL *Corresponding author e-mail: h_ikeda@um.u-tokyo.ac.jp

Chromosome numbers of 14 species of Cyperaceae recently collected from the Manaslu Himalaya in Central Nepal are presented. Chromosome numbers for Carex inanis Kunth (2n = 42), C. rufulistolon T. Koyama (2n = 46), and C. speciosa Kunth (2n = 44) are reported here for the first time. Our findings of 2n = 40 for Blysmus compressus (L.) Panz. ex Link, 2n = 46 for C. filicina Nees, and 2n = 32 for Isolepis setacea (L.) R. Br. differ from previously published reports. Chromosome numbers of C. atrofusca Schkuhr subsp. minor (Boott) T. Koyama (2n = 48), Cyperus haspan L. (2n = 26), Eleocharis congesta D. Don (2n = 20), Fimbristylis dichotoma (L.) Vahl (2n = 20), F. littoralis Gaudich (2n = 10), F. schoenoides (Retz.) Vahl (2n = 10), Lipocarpha chinensis (Osbeck) Kern (2n = 26), and Schoenoplectus juncoides (Roxb.) Palla (2n = 74) coincide with past reports. (85: 157-165)

Taxonomy of the Allies of Astilbe thunbergii (Siebold & Zucc.) Miq. (Saxifragaceae) in Shikoku, Western Japan

Shinobu Akiyama* and Yuichi Kadota Department of Botany, National Museum of Nature and Science, 4-1-1, Amakubo, Tsukuba, Ibaraki, 305-0005 JAPAN *Corresponding author e-mail: akiyama@kahaku.go.jp

The allies of Astilbe thunbergii (Siebold & Zucc.) Miq. including A. shikokiana Nakai and A. sikokumontana Koidz. (Saxifragaceae) in Shikoku, western Japan were studied. Astilbe shikokiana is a distinct species and A. sikokumontana is treated as a variety of this species. A new variety, A. shikokiana var. surculosa S. Akiyama & Kadota, is described, which has been erroneously treated as A. shikokiana in the former works. (85: 166-179)

Salicornia europaea L. (Chenopodiaceae) grows in saline places along seashores in the temperate regions of the Northern Hemisphere. In Japan, S. europaea is disjunctively distributed in eastern Hokkaido and in the Seto Inland Sea (Setouchi) area. The populations of S. europaea in Setouchi area have been thought to be introduced from Hokkaido by Kitamae Ships (trader ships between Hokkaido and Setouchi areas in the 19th century). In order to clarify the origin of S. europaea in the Setouchi area, we analyzed phylogenetic relationships among populations of S. europaea in Hokkaido, the Setouchi area, and Korea by using DNA sequence data of nrITS, atpB-rbcL and trnLtrnF. The haplotypes in Setouchi area were identical with those in Korea, and different from those in Hokkaido by three deletions and one or two substitutions. The results clearly reject the hypothesis that S. europaea in the Setouchi area is derived from Hokkaido. (85: 180-185)

Takehiro Ohmori Gunma Museum of Natural History 1674-1, Kami-Kuroiwa, Takaoka, Gunma, 370-2345 JAPAN e-mail: ohmori@gmnh.pref.gunma.jp

Summary: Sagina decumbens (Elliot) Torrey & A. Gray (Caryophyllaceae) is newly reported from Japan. Plants belonging to this species was found in Takasaki, Gunma Pref., central Honshu, Japan in 2009. Another collection in 1995 from Sakai, Osaka Pref., western Honshu, Japan was also identified as S. decumbens. Two subspecies are recognized in this species and from Takasaki and Sakai were ascribed to S. decumbens subsp. decumbens. (85: 192-194)

Records of Authors of Plant Names 1. Hiro Ohashi, Sadao Suzuki and Tuguo Tateoka

Hiroyoshi Ohashi Botanical Gardens, Tohoku University, Sendai 980-0862 JAPAN) e-mail: ohashi@mail.tains.tohoku.ac.jp

Summary: Records of authors of plant names are necessary for establishment of correct names as indicated in the Recommendation 9A in ICBN Vienna Code 2006 (McNeill et al. 2006). A standard form of the author names is adopted in ICBN from Authors of Plant Names (Brummitt and Powell 1992) and a standing column for new records is available in the website "IPNI Author Search" for continuous collections of plant name authors. In Japan records of plant-name authors have usually been published in several publications without standard forms or styles. Records of Japanese authors of plant names are often hard to find when necessary. In this note, the Japanese plant name authors who are insufficiently recorded in Japan as well as in "IPNI Author Search" are supplied here. This record includes: Japanese name (SURNAME + Forename) in Chinese characters, Forename + SURNAME in Romanized characters, (date of birth and death), [Plant groups studied in the same abbreviation with Brummitt and Powell (1992)], Standard form as the plant name author, Biography and major works, Example(s) of names published, Herbarium keeping the type and collection, and Information source. A Note related to the person is added when necessary. This first report includes 1) Hiro OHASHI, 2) Sadao SUZUKI and 3) Tuguo TATEOKA. (85: 194-196)
