Abstract
Epiphytic algae in mangrove forests contribute to high productivity in these unique mangrove ecosystems. A general survey of mangrove-associated macroalgae was conducted during February–March (dry season) and November–December (wet season) in the Sundarbans Mangrove Forest, Bangladesh. Different macroalgae were collected from mangrove pneumatophores, roots, and branches of trees. During this survey, a small and inconspicuous species of Chondria was encountered from the upper-middle of the intertidal zone in the Malancha River (22°5′11.37″ N and 89°13′12.37″ E). External–internal anatomical traits were examined and the sample was identified as Chondria intertexta Silva, a new record for the algal flora of Bangladesh. Furthermore, its geographical distribution and some other ecological notes are also discussed.
Highlights
Epiphytic red alga (e.g., Caloglossa sp., Chondria sp.) are commonly found in the intertidal [1,2].Most members of the genus Chondria (Rhodomelaceae, Ceramiales) occur in intertidal rocks, hard substrates, and solid objects they are rarely found in mangrove ecosystems [1,3,4,5,6] Agardh [7]established the red algal genus Chondria, which he characterized as having cartilaginous and filamentous thalli, with branches that are constricted at the base, and the main axes composed of five pericentral cells surrounding the axial cell

Chondria intertexta Silva is newly recorded from the Sundarbans forest, Bangladesh, and represents a new genus and species record for the marine flora of Bangladesh
Summary
Established the red algal genus Chondria, which he characterized as having cartilaginous and filamentous thalli, with branches that are constricted at the base, and the main axes composed of five pericentral cells surrounding the axial cell. 35 benthic algae (Chlorophyceae (14 spp.), Cyanophyceae (9 spp.), Phaeophyceae (1 sp.), Rhodophyceae (7 spp.), and Xanthophyceae (4 spp.)). Later on, he described the ecology and taxonomy of marine algae from Bangladesh, and 165 species belonging to 77 genera classified within Chlorophyta (38 spp.), Chrysophyta (5 spp.), Cyanophyta (27 spp.), Phaeophyta (46 spp.), and Rhodophyta (49 spp.) [10]
