Japanese alpine fleabane, ‘Miyama-azuma-giku’ in Japanese, is a typical Japanese alpine plant. The names Erigeron thunbergii A.Gray var. glabratus A.Gray or E. thunbergii subsp.
glabratus (A.Gray) H.Hara & Kitam. have been predominantly adopted for the plants. However, a reexamination of the type specimen preserved at GH reveals that E. thunbergii var. glabratus is distinct from the Japanese alpine fleabane. To discover its identity, a field survey was undertaken at the type locality and plants similar to the type specimen were gathered. As the plants are quite distinct from E. thunbergii, a new name E. mutsuensis Kadota is provided for Erigeron thunbergii A.Gray var. glabratus A.Gray. Consequently, E. alpicola Makino is considered to be the correct name for Japanese alpine fleabane. The lectotype of Erigeron alpicola Makino is designated. Under E. alpicola, five varieties, i.e., var. angustifolius (H.Hara) Kadota, var.
haruoi (Toyok.) Kadota, var. heterotrichus (H.Hara) Kadota, var. kirigishiensis (Inagaki & Toyok.) Kadota, and var. schikotanensis (Barkalov) Kadota are recognized. Additionally, a new rheophytic variety, E.alpicola var. riparius Kadota, is described from Shimukappu, Hokkaido, northern Japan.

Six lichenicolous fungi, Abrothallus parmeliarum, Arthonia digitatae, Lichenopuccinia poeltii, Reconditella physconiarum, Stigmidium subcladoniicola, and Vouauxiella lichenicola, are reported as new to Japan. These were found on the host lichens collected in montane to subalpine area of Nagano and Saitama Prefectures in central Honshu and Hokkaido in Japan.

Although shoot organization in the Vitaceae, a family of about 900 species has long been interested in and studied, the number of the species examined are limited and observations have been insufficient. In this study, based on the morphological observations on some species of the Vitaceae cultivated or growing wild in Japan, their shoot organizations are described and compared, and following comments are presented: 1) Causonis japonica (= Cayratia japonica) has short shoots terminated by an inflorescence in the tendril-less nodes. 2) As the arrangement of the first scaly leaves (bracts) on the tendril of Parthenocissus tricuspidata succeeds the phyllotaxis of the main shoot, the tendril may be considered to be a part of a sympodial unit of the shoot. 3) Among the species examined, the ventral placement of the first leaf of the secondary shoot was observed only in Ampelopsis glandulosa (= A. brevipedunculata). 4) The structure of short shoot of Parthenocissus tricuspidata appears to be complex: After two foliage leaves, it may produce inflorescence(s), a tendril and a continuation shoot.

Traditionally the leaf arrangement of the genus Humulus (Cannabaceae) has been described to be opposite. But alternate leaf arrangement is also found in H. scandens. The phyllotaxis and branching patterns of H. scandens are observed and described. The leaves are arranged oppositely in vegetative growth and generally changed into alternate in the reproductive stage. Three types are recognized in the arrangement and growth of the axillary buds.
