Rosenvingea
Rosenvingea is a genus of brown algae first described by Frederik Børgesen in 1914.
The lectotype species is Rosenvingea sanctae-crucis Børgesen and named for the Danish phycologist Lauritz Kolderup Rosenvinge.

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.
