VEGETATIVE AND REPRODUCTIVE MORPHOLOGY OF HERPOCHONDRIA-CORALLINAE (MARTENS) FALKENBERG AND HAPLOCHROMIS-ELEGANS (OKAMURA) ITONO (CERAMIACEAE, RHODOPHYTA) FROM KOREA

The vegetative and reproductive morphology of two epiphytic Herpochond ria species, H. corallinae (Martens) Falkenberg (the type species) and H. elegans (Okamura) Itono from Korea were investigated. They are bil aterally compressed and alternate-distichously branched, and lateral b ranches are produced by oblique divisions of the apical cell. Procarps are restricted to the first periaxial cell of the branches. Spermatan gial mother cells produce one or two spermatangia. H. corallinae forms tetrasporangia on six periaxial cells, whereas H. elegans has them on only the two lateral periaxial cells. The prostrate habit, the produc tion of six periaxial cells in opposite pairs, and tetrasporangial sti chidia are confirmed as diagnostic characters of the genus Herpochondr ia.
