many. These are products for men and women,
and include toners, moisturizers, cleansers, emulsions,
essences, astringents, eye creams, wash gels, shower
gels, shave balm, hydration sprays and creams, and
masks [6.462]. Extracts have antimicrobial [6.201],
anthelmintic [6.354], and antioxidant [6.335, 463]
activity.
Haliptilon attenuatum (Kützing)
Garbary & H.W. Johansen
Description. Thallus habit: erect, bushy with dense
not entangled fronds (D). Size: 22:5 cm high. Branching: alternate, dichotomic-pinnate (D-A) (whorled);
distal dichotomous branchlets. Intergenicula: cylindrical, tapered near apices, 0:20:4 .0:5/ mm long,
0:070:1 mm in diameter. Genicula: 60200 m long.
Color of living specimen: from red scarlet to purple.
Color of dried specimen: from white to ivory yellow [6.464].
Habitat. Epiphytic species often on H. virgatum;
mainly on sublittoral.
Distribution. Alboran Sea: Morocco; Middle Western Mediterranean Sea: Italy; North Adriatic Sea: Italy,
Croatia.
Uses and Compounds. Extract has antibacterial activity [6.60].
Jania adhaerens J.V. Lamouroux
Description. This species is small (45 mm high),
heavily calcified, and forms intricately entwined
clumps. The branches are pinkish-red color, regularly dichotomous, terete or slightly compressed,
and slightly curve downward. Terminal segments
are acuminate. This is an epiphytic species, decumbent on other seaweeds such as the species
of Sargassaceae, growing in the sublittoral zones
along shorelines moderately exposed to water movement [6.465].
Habitat. Growing in the sublittoral zones along shorelines moderately exposed to water movement.
Distribution. Atlantic Islands; Mediterranean; SW
and SE Atlantic; Caribbean; Indo-Pacific Oceans;
Australia.
Uses and Compounds. Extracts have antigenotoxic
[6.466], antifungal, antiviral, and antimicrobial [6.62,
103] activity.
Jania rubens (Linnaeus) J.V. Lamouroux
Description. Slender, rose-pink, articulated, calcified
fronds, to 50 mm high; repeatedly dichotomously
branched, luxuriant specimens secondarily pinnate
(Fig. 6.23). Segments cylindrical, to 120 m diameter, those bearing branches somewhat compressed,
to 180 m diameter. Fixed by small conical disk,
