Pollen grains of nine species of Dendrolobium and four of Phyllodium were described and illustrated based on observations by scanning (SEM) and transmission (TEM) electron microscopy in order to add new pollen characters to existing data provided by LM observations. The pollen grains of the two genera are fundamentally similar in morphology of the pollen type, sculpture of the exine, structure of the colpus, and structure of the exine, but show differences in shape and membrane of the colpus and thickness of the sexine. The results suggested closer relationships between these genera than previously considered. (86: 333–349)

The fine structure of a marine tube-forming diatom Berkeleya rutilans, has been examined by light and electron (SEM and TEM) microscopies. The following morphological features of this species are revealed in detail through the present study. B. rutilans has the asymmetrical axial area, the striae consisted of elongate areolae adjacent to the central area, the areola occluded by the hymen with perforations arranged in regular scatter, and the perforated open bands consisted of two types.   (Continued from J.

As a part of our botanical inventory program, field surveys of supposedly sibling entities of Chinese/Japanese herbal medicinal species were carried out. From our collections seven species, Coptis aspleniifolia Salisb. (Ranunculaceae), Paeonia brownii Douglas ex Hook. (Paeoniaceae), Gentiana sceptrum Griseb. (Gentianaceae), Nuphar polysepala Engelm. (Nymphaeaceae), Fritillaria affinis (Schultes) Sealy, F. camtschatcensis Sweet and F. pudica Spreng. (Liliaceae) were studied taxonomically in comparison with their Asian counterpart taxa. Related chemical analyses were made by means of thin-layer chromatography, colour test by Dragendroff’s reagent and/or in part high performance liquid chromatography. The chemical analyses proved the existence of active components within three species, suggesting certain possibilities in using these North American plants as substitutes of medicinal plants of Japanese Pharmacopeia.

Typification of Acer miyabei Maxim. (Aceraceae)

Hideki Takahashia,*, and Alisa Grabovskaya-Borodinab aThe Hokkaido University Museum, Hokkaido University, Sapporo, Hokkaido, 060-0810 JAPAN bKomarov Botanical Institute, Russian Academy of Science, Prof. Popov Street, 2 St. Petersburg, 197376 RUSSIA *Corresponding author: hide@museum.hokudai.ac.jp

The type specimen of Acer miyabei Maxim. at LE consists of flowering and fruiting elements. These two elements are considered to be syntypes, therefore, Popova’s use of holotype for the flowering specimen of A. miyabei Maxim. is an error to be corrected as lectotype under ICBN Art. 9.8. Isolectotypes of A. miyabei are also at GH, SAPS and TI. (86: 367–370)

A New Name for a White-Flowered Form of Prunella vulgaris subsp. asiatica (Lamiaceae)

A new name Prunella vulgaris L. subsp. asiatica (Nakai) H. Hara f. leucocephala K. Ohashi, H. Ohashi & Yonek. is proposed for a white-flowered form of P. vulgaris subsp. asiatica, as the replacement name of P. asiatica var. albiflora Nakai or P. asiatica f. albiflora (Nakai) Kitag. (86: 371–373)
