Ophiopogon chingii F.T.Wang & Ts.Tang, O. hainanensis Masam., O. platyphyllus Merr. & Chun and O. latifolius L.Rodr. are taxonomically reinvestigated. Ophiopogon chingii var. glaucifolius F.T.Wang & L.K.Dai is not clearly demarcated from var. chingii. This species is exceedingly variable, occurring in China and Vietnam. Some specimens from Vietnam formerly recorded by Rodriguez (1934) as O. reptans Hook.f. are identified here as O. chingii. Ophiopogon reptans recorded from Hainan Island (China) is also highly likely to be O. chingii. Ophiopogon hainanensis is regarded as conspecific with O. chingii. Ophiopogon chingii, O. platyphyllus and O. latifolius differ at least in the apical form of the ovary.

Distribution of 31 popular plants (Table 1 and Figs. 2 to 9) in Kagawa Prefecture, Shikoku, western Japan was surveyed in cooperation with local botanists. Reynoutria sachalinense is not found. Adenocaulon himalaicum, Kerria japonica, Geranium thunbergii, Macleaya cordata and Youngia denticulata are retired to hill region and being not ‘popular’ here.

To determine the correct application of the name Rosa luciae Rochebr. & Franch. ex Crép. and its varieties proposed by Franchet and Savatier in Enumeratio Plantarum in Japonia （1873, 1878）, the type and other authentic specimens deposited in the Muséum Natiónal d'Histoire Naturelle, Paris, were examined. Lectotypes of Rosa luciae Crép. and R. luciae var.δ. adenophora Franch. & Sav., and also neotypes of var. ζ. yokoscensis Franch. & Sav. and var.η. hakonensis Franch. & Sav. are selected.

Usnea subfloridana Stirt. and its related species in eastern Asia are taxonomically revised. Five species, U. florida, U. fulvoreagens, U. glabrescens, U. wasmuthii as well as U. subfloridana are recognized. While U. florida forms no asexual propagule, the other four are sorediate. Soralia morphology is particularly useful for distinguishing these four species, since its origin and development are different. Among the five species treated here, U. fulvoreagens and U. wasmuthii are newly recorded for eastern Asia.

Chromosome numbers of nine species of Saussurea collected in the alpine region in Khumbu Himal, Nepal, are reported. Two different chromosome numbers are counted in Saussurea gossypiphora and its allied species in section Eriocoryne （subgenus Eriocoryne）, i.e., 2n ＝36 from S. gossypiphora, S. nishiokae and S. tridactyla, and 2n ＝32 from S. simpsoniana and S. topkegolensis. The number of S. gossypiphora is different from the previous study （n ＝13）. Saussurea graminifolia in section Pycnocephala （subgenus Saussurea） is 2n ＝32. In section Amphiraena （subgenus Amphiraena） chromosome numbers of two species, S. obvallata and S. uniflora, are 2n ＝32, while that of S. hookeri is 2n ＝36. The chromosome numbers of S. nishiokae, S. tridactyla, S. topkegolensis, S. graminifolia S. uniflora and S. hookeri are recorded for the first time.
