| ABSTRACT |
|
Two unrecorded species of marine algae in Korea, Polysiphonia scopulorum Harvey and P. flaccidissima Hollenberg, are investigated taxonomically. P. scopulorum is characterized by its very small slender form, strongly developed prostrate system attached by rhizoids in open connection with the pericentral cells, erect filaments with short segments and few branches, rare scar cells and trichoblasts, and tetrasporangia forming slightly spiral series. P. flaccidissima is characterized by its limited prostrate branches, attachment by unicellular rhizoids cut off as separate cells from proximal end of the pericentral cells, lateral branches arising in association with trichoblasts mostly at intervals of 6-10 segments, trichoblasts delicate with 1-2 dichotomies, and branches slightly narrowed at the base. Pericentral cells of the both species are ecorticate, and 4 in number.
