  • This study reports on the morphological characteristics and distribution for conservation and practical use in the Korean Peninsula of Chrysosplenium flaviflorum through a comparison with relative species. The morphological characters that were newly investigated in this study included subhypogaeus stolons and glabrous on the surface of leaves. The former has not been described by any taxonomist who had previously treated this species with the exclusion of Hara. Despite this, the latter is a very important key to using the identification of varieties of Ser. Pilosa though there were no descriptions which included Ohwi. C. flaviflorum Ohwi which was endemic and known to be distributed only in the northern area of the Korean Peninsula, was also observed in the Gapyeong-gun, Gyeonggi-do, Cheorwon-gun, Gangwon-do, and Yeongdonggun, Chungcheongbuk-do middle area since the latest collection report in 1943. There is a requirement for further study to be conducted on the distribution and management by designation for the Special Plant Species by the Korean Ministry of Environment.

  • We have examined the pedicel pubescence and other major morphological characters of 11 putative hybrid populations of Aconitum subgn. Aconitum at Mt. Sobaek to understand their origin. These populations show very complicated patterns of variation in pedicel pubescence ; they contain individuals having pedicels (1) completely glabrous, (2) with few micropapillate curved hairs near the receptacle, (3) moderately pubescent with micropapillate curved hairs from middle to upper portion, (4) sparsely pubescent with a mixture of micropapillate curved hairs and smooth-surfaced spreading glandular hairs near the receptacle, and (5) moderately pubescent with both types of hairs but from middle to upper portion. All five types of individuals co-occur in most populations with varying proportions. These results, in conjunction with evidence from the analysis of other major morphological characters, suggest that the populations at Mt. Sobaek were derived from the multiple hybridization events involving A. kusnezoffii, A. japonicum subsup. napiforme, and A. jaluense subsp. jaluense. In addition, the absence of "typical" forms of these putative parental taxa in Mt. Sobaek area suggests that repeated introgression has probably occurred in these populations.
