Abstract

Two naturalized species, Polygonum ramosissimum Michx. (Polygonaceae) and Spergularia bocconi (Scheele) Graebn. (Caryophyllaceae) were found along the southwest seashore of the Korean Peninsula. Polygonum ramosissimum is distinguished from other species in the same genus taxa as follows: not granular achens, lanceolate or oblanceolate leaves. Spergularia bocconi is distinguished from other species in the same genus taxa by having glandular hairs on stems, leaves, peduncles, and outer surfaces of sepals. We provide here a description and photographs of two species and a key to related taxa in Korea.

미기록 귀화식물인 Polygonum ramosissinum Michx. (마디풀과)와 Spergularia bocconi (Scheele) Graebn. (석죽과)를 한반도 서남해안에서 발견되었다. 미국갯마디풀로 신칭한 P. ramosissinum은 잎이 도피침형이거나 피침형이며, 수과는 돌기가 없는 형태적 특징으로 속내 근연종들과 구분된다. 끈적털갯개미자리로 신칭한 S. bocconi는 꽃이 달리는 윗부분의 가지, 줄기, 잎에 샘털이 있으며, 특히 꽃자루와 꽃받침잎 바깥 면에 많은 샘털을 가지고 있는 형태적 특징으로 속내 근연종들과 구분된다. 본 연구는 미기록 귀화식물 2종에 대한 기재와 화상자료를 제공하고, 검색표를 작성하였다.
