Morphology
The genus Rosenvingea by Børgesen for branched, brown algae with hollow centers and an outer cellular component composed of large hyaline cells bearing a layer of small, pigmented cells, and plurangia borne in surface sori. It is furtherly distinguished by its erect thalli with alternate or dichotomous branches, an apical to subapical meristem, a single plastid and prominent pyrenoid in vegetative cells, and phaeophycean hairs.The branching pattern, which may be free in most species or co-adhering in some, are primarily used as taxonomic criteria for segregating the different taxa in this genus.
Distribution
The genus Rosenvingea Børgesen is a tropical to subtropical genus of Scytosiphonacean brown algae. Recorded occurrences include Florida, Bermuda, North Carolina, the Caribbean, Gulf of Mexico, Brazil, Mediterranean, Eastern tropical Atlantic, Red Sea, Indo-Pacific and Australia.Its heteromorphic life history coupled with its great tolerance to environmental conditions manages this genus to survive transport by different vectors.
