Ophiopogon intermedius D.Don occurring in south Asia is taxonomically reinvestigated. Ophiopogon clarkei＊, O. grandis＊, O. lushuiensis＊, O. zingiberaceus＊, O. merrillii＊, O. acaulis (=Chloopsis acaulis)＊, O. wallichianus (=Flueggea wallichiana), O. bodinieri, O. indicus and Flueggea jacquemontiana are treated as synonyms of O. intermedius (new synonyms are asterisked). All the varieties of O. intermedius and O. wallichianus described by Hooker (1892) are also treated as the same taxon as O. intermedius. D'ons O. spicatus may also be conspecific with O. intermedius, as reported in some previous papers. Ophiopogon intermedius is an exceedingly variable species with an extensive range of distribution in Asia.

Seven new species of Pedicularis, P. elsholtzioides, P. lhasana, P. liguliflora, P. ningjuingensis, P. columbigera, P. kuruchuensis and P. cholashanensis are described from Tibet (Xizang) and Sichuan, China.

New combinations for the Japanese taxa of Schoenoplectus (Rchb.) Palla (Cyperaceae) are proposed; i.e., Schoenoplectus orthorhizomatus (Arai & Miyam.) Hayasaka & H.Ohashi, Sch. ×igaensis (T.Koyama) Hayasaka & H.Ohashi, Sch. ×oguraensis (T.Koyama) Hayasaka & H.Ohashi, Sch. ×trapezoideus (Koidz.) Hayasaka & H.Ohashi and Sch. ×uzenensis (T.Koyama) Hayasaka & H.Ohashi.

The shape of inflorescences of the Himalayan species of Impatiens was studied. Nine types were recognized: 1 to 6 are racemes while 7 to 9 do not fit for the typical racemose inflorescence. The latter types were observed in Himalayan species but not in African ones. The correlations between the inflorescence type and the basic chromosome number were discussed.

Flowers of Sasa jotanii (Poaceae: Bambusoideae) from Isl. Mikurajima, Izu Islands, Japan, are observed on the basis of new flower characteristics and a new specific status of it is proposed here. Comparing the species with the most related allies, S. kurilensis and S. tsuboiana, S. jotanii is characterized by a large fusiform, incanus reddish-purple spikelet 25-36 (-40) mm long, 7-12 mm wide, extremely large elliptic non-dormant caryopsis (14.5-) 17-21.5 mm long in reproductive organs; its less decumbent culms, coriaceous and waxy foliage leaves, and lanceolate leaf blade without oral setae and sheath-margin fimbriae in sterile organs. Sasa jotanii is probably most closely related to S. kurilensis belonging to the section Macrochlamys.

Flower visitors of four species of Lespedeza subgen. Macrolespedeza were observed in Korea for the first time. The major flower visitors were apoid bees, especially Apis, Tetralonia, Megachile, and Bombus. They showed a considerable degree of flower constancy to Macrolespedeza judging from analyses of pollen loads, hence they were considered to be important pollinators for Macrolespedeza. Significant differences were not observed in flower visitor fauna among the species except L. melanantha which represented predominance of Bombus. Although the predominance of Bombus has not mentioned so far in Lespedeza, it was the most important pollinator for L. melanantha.
