Vicia sect. Amurense (tribe Fabeae, family Leguminosae), consisting of four species, is mainly distributed in western China. The species of the section share a terete style, a globose stigma, and a swollen pollen mesocolpium. However, in recent molecular phylogenetic studies of Vicia, species with a terete style were presumed to be polyphyletic. In order to clarify phylogenetic relationships of the species of sect. Amurense we did a molecular phylogenetic study comparing data from the ITS region of nrDNA and matK of the chloroplast genome. The analysis showed sect. Amurense to be nested in a clade corresponding to sect. Vicilla, which contains mainly East Asian Vicia species. The monophyly of sect. Amurense was not supported. This discrepancy between the phylogenetic relationships of sect. Amurense presumed from the floral and pollen morphological characteristics and those from the molecular phylogenetic analysis indicates needs of further phylogenetic studies on the section.

Volvulina Playfair is a colonial volvocalean genus with usually 8 or 16 cells forming hollow ellipsoidal colonies. In this study, a strain of Volvulina was isolated from Lake Tsukui, Kanagawa Prefecture, Japan. This strain was morphologically identified as Volvulina compacta Nozaki, which was previously known only from strains isolated from Nepal. Chloroplast multigene analyses using rbcL, atpB, psaA, psaB and psbC genes showed that the Japanese strain of V. compacta is closely related to the Nepalese strain of V. compacta and to an American strain of Volvulina pringsheimii Starr, but only distantly to Volvulina steinii Playfair previously reported from Japan. Although the Japanese strain was more closely related to V. pringsheimii than to Nepalese V. compacta, it was clearly distinguished from V. pringsheimii by its square cell shape in the top view. These results indicate the existence of cryptic species within V. compacta. (85: 364–369)

Carex ×musashiensis Ohwi is newly reported from Miyoshi-shi, Tokushima Pref., Shikoku. This plant was described from Mt. Takao, Tokyo, as a hybrid between C. curvicollis Franch. & Sav. and C. thunbergii Steud. However, this plant is reinterpreted as a hybrid between C. curvicollis and C. forficula Franch. & Sav. by the ecological and morphological evidence at the new locality. The lectotype of C. ×musashiensis is deginated here. (85: 297–302)

In the course of floristic research of Myanmar, we found Eleiotis sororia (L.) DC. as new to the flora. This is the easternmost end of distribution of this species. The nomenclatural confusion of this species is reviewed and the lectotype is designated here. Detailed illustrations of flower, fruit and seed are presented as well as their descriptions. Conspicuous indumentum in the inflorescence and anatomical features of the fruit with respect to the joint structure are described in detail. (85: 303–312)

Nine species of seven genera in the family Graphidaceae are recognized as Cambodian member of the lichens and their distribution ranges are presented. Among them, one species, Graphis cambodiensis M. Nakan., Kashiw. & K. H. Moon, is new to science. It is distinct from allied species of the genus in having prominent lirellae covered by thallus nearly up to the exciples, muriform spores 75–105 × 20–30 μm in size and in producing norstictic acid. Graphis commaculans Vain. is reduced to a synonym of Sarcographa gyrizans (Leight.) Mu?ｽNll. Arg. The following seven species, Carbacanthographis induta (Mu?ｽNll. Arg.)

A cytological study of two narrow endemic Carex (Cyperaceae), C. omurae T. Koyama and C. phaeodon T. Koyama, was performed. Chromosome numbers of C. omurae (2n = 32) and C. phaeodon (2n = 30) were determined in this study for the first time. Phylogenetic relationships of C. omurae and C. phaeodon, with their allied species, are discussed. (85: 370–373)

Southernmost Localities of Schoenoplectus orthorhizomatus (Kats. Arai & Miyam.) Hayas. & H. Ohashi (Cyperaceae) and Its Habitats

Takehiro Ohmori Gunma Museum of Natural History ohmori@gmnh.pref.gunma.jp

Schoenoplectus orthorhizomatus (Kats. Arai & Miyam.) Hayas. & H. Ohashi (Cyperaceae), which has been known in northern Japan, is newly recorded from Oze, Mt. Hotaka and the Madarao Highland, in central Honshu, Japan. The species is distributed in areas covered with heavy-snowfall in winter from Hokkaido to central Japan. The species mainly grew in disturbed stands of fen, such as streamside of peatland, foot of peat plateau and trampled ground, while S. hondoensis (Ohwi) Soják, a close relative of S. orthorhizomatus, mainly grew in pools (undisturbed stands) of bog.

P. O. Box 9446, Kathmandu, NEPAL

Chromosome numbers of four species of Cyperaceae collected from Far West Nepal are presented. The chromosome number for Carex gracilenta Boott ex Boeck. (2n = 52) is reported for the first time. Our finding of 2n = 46 for C. longipes D. Don differs from previous reports. It seems that C. longipes may consist of a series of aneuploids. Chromosome numbers of C. fusiformis Nees (2n = 44) and Eleocharis palustris (L.) Roem. & Schult. (2n = 16 = 4L+12S) agree with the previous reports. (85: 378–382)
