Abstract

A new species, Carex brevispicula G. H. Nam & G. Y. Chung (Cyperaceae), was found in Korea. Carex brevispicula is similar to the related species C. chungii Z. P. Wang and C. genkaiensis Ohwi in that its achenes are constricted in the middle part. However, C. brevispicula is distinguished from C. chungii as the plants, staminate, and pistillate spikes are shorter and its pistillate scales are pale green; C. brevispicula is distinguished from C. genkaiensis by its awned staminate and pistillate scales. The scientific name of this new species was based on the fact that its inflorescence is shorter than that of C. chungii. The corresponding Korean name, "Jom-mok-po-sa-cho," means that the plants of this species are smaller than the "Mok-po-sa-cho" types (C. genkaiensis). We hereby provide a description of C. brevispicula, with corresponding illustrations and photographs, a distribution map, and a key of related taxa.

사초과의 좀목포사초(Carex brevispicula G. H. Nam & G. Y. Chung)가 한국에서 처음으로 발견되었다. 좀목포사초는 수과의 중앙부가 함몰되는 점에서 큰청사초(C. chungii Z. P. Wang) 및 목포사초(C. genkaiensis Ohwi)와 유사하다. 그러나 좀목포사초는 식물체, 웅화서와 자화서가 소형이고, 자인편이 연녹색인 특징으로 큰청사초와 구분되며, 자인편과 웅인편에 까락이 있다는 점에서 목포사초와 차이를 보인다. 새로운 국명은 목포사초보다 작다는 의미로 좀목포사초로 하였고, 주요형질에 대한 기재, 도해, 사진, 분포정보 및 근연분류군과의 차이점을 검색표로 제시하였다.
