Abstract

Porphyra suborbiculata Kjellman (Bangiales, Rhodophyta) collected from Mazin, Hlyaw-Gaung-Taung (Satt-Thwa) and Mwe-Taung, Zee Gyaing Village, the Mawtin Point, the Rakhine Coastal Region and Maungmagan, the Tanintharyi Coastal Region, Myanmar, is described based on both the morphology and life history found in laboratory cultures and field. The materials used in this study show Porphyra lacerata type of life history: heteromorphic alternation of generations-conchocelis phase and monoecious leafy thalli phase. In addition, the developmental sequence of formation and germination of archeospores (bispores) in P. suborbiculata was acknowledged as
asexual mode of reproduction usually occurred prior to the development of sexual structures. The taxonomy of Porphyra suborbiculata Kjellman from Myanmar and other related plants such as P. crispata Kjellman and P. vietnamensis Tanaka et Pham-Hoang Ho found in Asiatic waters is briefly discussed.
