Upon checking 'Illustrated Flora of Korea' which was published in 1980, there were more than ca. 150 apparently invalid names for the Korean plants, which were nomen nudum as well as new combinations or avowed substitutes by T. B. Lee. These names were based on previously and invalidly published names from 'Handbook of Korean Forestry Sciences' and 'An Enumeration of Plants Hitherto Known from Corea'. We consider it useful to summarize the results of this investigation and these invalid names of Korean plants were enlisted here. These invalid names should not be used any more even as synonyms in the literatures.

Several people called our attention to two books in which many new name were made by T. Nakai. Upon checking Mori and Handbook of Korea-Mandschurian Forestry, we found that there were more than 50 apparently overlooked and naked names for the Korean woody plants. Also, new combinations or avowed substitutes of some woody plants by several authors (Y. Lee, T. Lee and W. Lee) based on previously and validly published names were not validly published because their basionyms or the replaced synonyms were not clearly indicated and a full and direct reference was not given to their authors and places of valid publications, with pages or plate references and dates. These names should not be used any more. We consider it useful to summarize the results of this preliminary investigation and invalid names of woody plants are enlisted here. Hopefully, this note will alert other researchers to look into these works for other herbaceous Korean plants.

Somatic chromosome counts and karyotype analyses were carried out for eight taxa of Korean Allium sect. Sacculiferum. The basic chromosome number of sect. Sacculiferum was x = 8, and they could be cytologically divided into two groups, that is, a diploid group (2n = 2x = 16) containing A. thunbergii var. thunbergii, A. thunbergii var. deltoides, A. thunbergii var. teretifistulosum, A. deltoidefistulosum, A. longistylum, A. linearifolium and A. taqueti, and a tetraploid group (2n = 4x = 32) with only A. sacculiferum. All observed chromosomes were classified into metacentric, submetacentric and subtelocentric. The metacentric ones appeared in all treated taxa. One or two pairs of submetacentric chromosomes were observed in most taxa except A. sacculiferum, the unique taxon with subtelocentric chromosomes. All taxa had a pair of homologous chromosomes with satellites, and the B-chromosomes found in A. thunbergii var. thunbergii, A. deltoidefistulosum, A. sacculiferum and A. longistylum, were metacentric or telocentric. The karyotypes of A. longistylum and A. linearifolium were firstly investigated in this study. In conclusion, the somatic chromosome numbers and karyotypes for members of the sect. Sacculiferum were valuable characters in identifying taxa, investigating interspecific relationships and delimiting taxa. In addition, A. thunbergii var. teretifolium, an invalid name (homonym), was renamed as A. thunbergii var. teretifistulosum H. J. Choi & B. U. Oh.

To confirm the taxonomic identity of taxa described by $L{\acute{e}}veill{\acute{e}}$, H. H. A, a French plant taxonomist, in the serial papers of Decades plantarum novarum based on the collections of Fathers Faurie and Taquet from the Korean peninsula, we examined the numerous references that contained taxonomic opinions about $L{\acute{e}}veill{\acute{e}}^{\prime}s$ taxa. Among them, 146 taxa were confirmed as conspecific with other existing taxa. Of them, 79 taxa, including Ajuga devestita, were listed as a synonym of only one species. Sixty-seven taxa, including Bidens robertianifolia, were listed as synonyms of two or more species according to taxonomists. Eight taxa, including Aconitum coreanum, were considered illegitimate names because of later homonym, or other problems. Five taxa, including Rhododendron hallaisanense, were treated either as distinct or conspecific taxa depending on taxonomists.
