  • 국화과에 속하는 미기록 귀화식물 2종이 강원도와 제주도에서 확인되었다. 미기록속인 미역취아재비속(Euthamia Nutt.)에 속하는 미역취아재비[Euthamia graminifolia (L.) Nutt.]가 강원도 인제군에서 발견되었다. 이 종은 선점이 있고 전연인 잎과 맥이 없는 통상화관에 의해 미역취(Solidago japonica Kitam.) 및 미국 미역취(S. gigantea Aiton)와 구별된다. 국명은 미역취와 유사하여 '미역취아재비'로 신칭하였다. 또한 미국풀솜나물[Gamochaeta pensylvanica (Willd.) Cabrera]이 제주도에서 발견되었다. 이 종은 개화기에 없어지는 근생엽과 더 짧은 내총포에 의해 자주풀솜나물[G. purpurea (L.) Cabrera]과 구분된다. 국명은 종소명을 고려하여 '미국풀솜나물'로 신칭하였다.

  • Gnaphalium L. is a small herbaceous genus comprising up to 80 species in worldwide (Asia, North to South America, Africa, and Oceania). This genus is highly polymorphic which embrace uncommon broad morphological boundary, and thus further studies were needed to proper taxonomic delimitations for the genus and its relatives. Gnaphalium uliginosum L. was usually found in moist sites such as margins of lake, pond, reservoir, stream banks and paddy field. This squat plant is solely known species in Korean Gnaphalium. During the revisionary study of the tribe Gnaphalieae (Asteraceae) in Korea, however, we found several materials in domestic herbaria (e.g., SNU, KWNU) that identified as G. uliginosum or Gamochaeta pensylvanica (Willd.) Cabrera collected from central to northern Korea, but clearly differ to the morphology of G. uliginosum. The external morphology of the materials is seemingly the only feature at odds with G. uliginosum. However, its morphological characters such as tall erected stems (ca. 30cm), hairs on seeds and whitish tomentose hairs on the whole plants are easily distinguished from G. uliginosum, and rather it looks like G. tranzschelii Kirp. Although the name G. tranzschelii have been treated as synonym of G. uliginosum by several authors, its distinct morphology might be sufficient to separate to two independent taxa. Generally, the morphological polymorphisms and hybridization of G. uliginosum complicate the taxonomy of the species, and thus further investigation for their habitat, distribution and morphology were needed to their taxonomic entity.
