The morphotaxonomic characters and life history of Symphyocladia latiuscula (Harvey) Yamada were investigated with field and laboratory culture materials. The species is well defined by a 5-15 cm hight, entirely corticated thallus and congenital fusion of 5-7 segments between main axis and laterals. Although all the reproductive structures are basically similar to those of other species of the genus, it is characteristic that the pinnulae are transformed into the flabellated tetrasporangial stichidia. Vegetative trichoblasts are known to be absent in the Pterosiphonieae, but their presence in S latiuscula does not accept its taxonomic position in that tribe. As a result, the occurrence of vegetative trichoblast is not useful for a taxonomic character to distinguish the tribes. The species shows a Polysiphonia-type life history involving a dimorphic alternation of gametophytes and sporophytes in culture and field. It grows below the middle intertidal zone in all the coasts of Korea throughout the year, although fertile plants are normally found during the summer months.months. |
