Scinaiaceae Explained

Scinaiaceae is a family of red algae (Rhodophyta) in the order Nemaliales.[1] [2]

Huisman had placed former members of Galaxauraceae family, that were lacking lime into his new family of Scinaiaceae.[3]

Distribution

The family has cosmopolitan distribution.[4] Including being found in India,[5] [6] Arabian Sea,[7] Brazil,[8] North America (including Alaska, British Columbia, Washington, and Oregon[9]) Chile, New Zealand (Tasmania and Campbell Island) and the Falkland Islands.[2]

Notes

Molecular analyses of DNA on species of Nothogenia has been carried out to determine species relationships.[2]

Most Scinaiaceae species produce mucilage (thick, gluey substance) mainly in the cortical layer.[10]

Several species in the Scinaiaceae family (including Nothogenia fastigiata and Scinaia hatei) have been screened for anti-viral activity (against herpes, Respiratory syncytial virus (RSV), Influenzavirus A, Influenzavirus B and simian immunodeficiency viruses). Sulfated polysaccharides (xylomannans) from the red alga, have inhibitory effects.[11] [12]

List of genera

Former genera; Ginannia, Haloderma, Myelomium, Pseudogloiophloea and Rhodosaccion .[13]
