Abstract

A newly naturalized plant, Amaranthus powellii S. Watson was found Jail-dong, Uijeongbu-si, Gyeonggi-do, Korea. This species is native to Southwestern USA and Northern Mexico, and it is also naturalized in worldwide of temperate regions. This species was distinguished from the related species, A. patulus Bertol. and A. hybridus L., by leave blades broadly elliptic, rhombic or lanceolate, petals unequal, without conspicuous green mid-veins, and utricle gradually narrowed toward the stigma. Korean name was given as 'Min-teol-bi-reum' to A. powellii S. Watson, based on the character, it was hairy less than the three related species, A. patulus Bertol., A. hybridus L. and A. retroflexus L., conspicuously. Descriptions for mophological characters, photographs, illustrations and keys to allied taxa were provided.

한반도 미기록 귀화식물인 민털비름(Amaranthus powellii S. Watson)을 경기도 의정부시 자일동에서 발견하였다. 본 종은 미국 남서부와 멕시코 북부 원산으로 현재 전세계 온대지역에 널리 귀화된 상태이다. 본 종은 근연분류군인 가는털비름(A. patulus Bertol.)과 긴털비름(A. hybridus L.)에 비해 잎은 넓은 침형, 능형 또는 피침형으로 화피편의 길이가 서로 다르고 뚜렷한 녹색의 중앙맥이 없으며 열매가 주두쪽으로 올라가면서 서서히 좁아지는 특징으로 구별된다. 국명은 가는털비름, 긴털비름, 털비름(A. retroflexus L.)과 유사하나 줄기와 잎에 털이 현저히 적은 특징을 바탕으로 '민털비름'이라 하였다. 본 분류군의 외부형태적 특징에 대한 기재, 사진, 도해 그리고 근연분류군과의 검색표 등을 제시하였다.
