One species, Rhodolachne radicosa Itono, has been reported from mangroves, a common habitat for Bostrychia. Many collections of an entity similar to Rhodolachne radicosa have been made from localities around the Indo-Pacific. Culture observations show a Polysiphonia-type sexual life history in Malaysia and New Caledonia isolates that produce self-compatible bisexual gametophytes. The New Caledonia isolate also has unisexual gametophytes. An iso..
