ABSTRACT
Morphology and reproduction of Polysiphonia morrowii Harvey was studied based on materials collected in Sokcho on the eastern coast and in Daechon on the western coast of Korea. Plants height and L/W ratio of segments in Sokcho and Daechon varied significantly in different months and life history phases. The procarp consisted of four-celled carpogonial branch and two sterile cell groups. The spermatangial branchlets arose replacing whole trichoblast. Straight series of tetrasporangia was formed both on ultimate and axillary branchlets. Morphological features of Korean P. morrowii plants seem to be overlapped with a rang of P. senticulosa. The taxonomic relationship between two species is discussed.
Key words: morphology, Polysiphonia morrowii, P. senticulosa, reproduction, Rhodophyta, taxonomy, variation
