| Abstract: |
| Taxonomical studies on green alga Enteromorpha prolifera were carried out. The algae formed a large scale of floating swarm along near-shore area of western Yellow Sea recently in summer 2008, causing a heavy burden of cleanup for the sailing competition of the 29th Olympic Games held in Qingdao City. This species is characterized mainly by thallus, 1—2m high and 1—2cm thick, dark or light green, tubular compressed, hollow frond, distinct main branch, dense and slender long branches, irregularly arranged, polygonal or sub—cycloid cells, 7—20 μm long and 7—15 μm wide at upper part, 7.5—18 μm long and 7.5—15 μm wide at middle part, and 8—17 μm long and 8—15 μm wide at lower part of thalli, square or rectangle cells leaning to a side on transverse section with 10—15 μm and 10—15 μm, 10—12 μm and 10—16 μm, 15—30 μm and 10—15 μm respectively, cell with one pyrenoid, sometimes 2—5. Its habit, distribution, and reproduction were also presented in details.
