Thallus various in form and size, algiform, ribbon-like, to 
1 cm. broad and 5-50 cm. long, freely branched, creeping, or 
floating from attached base, or partly creeping and partly 
floating. Secondary shoots marginal ; the basal, rarely all 
or most, ultimately floriferous, 2-4 mm. apart, usually closely 
crowded when in flower. Flower buds usually sessile by 
broad base, bracts helmet-shaped. Pedicel of fruit in 
different varieties 6-40 mm. S.W. India and Ceylon. 
Thallus Fucus-like or loriform, 2-10 mm. wide at base in different 
forms, tapering, of varying length from 5-50 cm., usually frequently 
branched, ribbon-like, oval in section, fleshy, often crisped or undu- 
lated, attached at the base by a stout foot, less often by a creeping 
portion, and frequently attached by haptera or hairs at other places or 
sometimes at all points. Secondary shoots oo on upper side, at the 
margins or very rarely in the central parts, 2-4 mm. apart, usually 
closely crowded when floriferous owing to the size of the buds. Lower
