Cystoseira

 

a genus of brown algae of the order Fucales. The shrubby, mainly perennial plants are 0.5 to 2 m long (less commonly, as much as 8 m long) and have cylindrical or flattened branches, often with air sacs. Reproduction is sexual, consisting of oogoniums with a single egg cell. There are about 30 species, distributed mainly in seas of the northern subtropical zone. Three species occur in the USSR: two in the Black Sea and one in the seas of Japan and Okhotsk. The algae yield alginic acids and alginates, which are used in the food and textile industries.

Like the lines on a hand, the algae appear to depart from a few stronger branches to dance rhizomatically: perhaps both the open hand (a well-known symbol in Indian national iconography-think of Le Corbusier's work at Chandigarh) and the Cystoseira foeniculacea stretch themselves outwards to identify magnetically with the stars.
