Keyari in Japanses

When Spring has come, we can see the algae which have a head like a small Pom Pom Ball on the end of branches. This algae is popular as the background of a photo of fish. This is Sporochnus radiciformis (R. Brown ex Turner) C. Agardh. It belongs to Class Phaeophyceae, Family Sporochnaceae. It is a distributed Pacific side south from Kanto. It is called “Keyari” in Japanese. At the Edo era (1603-1868), when a lord traveled as a corp, decorated spear, named Keyari, is used as the mark of the corp head, so it is called Keyari as the common name. This algae is distributed in Australia also. Please tell me a common name in English. Kushimoto, Wakayama, Japan.
