Ulva fasciata

Ulva fasciata Delile

St. George: 3, 67–348, abundant on the shore rocks between tide levels. St. Joseph: 4, 67–396, frequent on the rocks in a dwarf form. St. John: 8, 67–487, tufts of a dwarf form drifted ashore. St. Andrew: 12, R–218, common on the reef. St. Mark: 6, 67–428, R–279, frequent on the rocks along the peninsula to Scotts Head, and infrequent on small stones in sandy areas.

Grieve (1909, p. 8) mentions the presence of this alga on Dominica without giving a definite locality. About the island, as elsewhere in the West Indies, the aspect of U. fasciata varies a great deal. In the narrow and branched form it is at once recognizable, but at times the resemblance to U. lactuca v. rigida is great, especially in crowded, dwarfed forms, and microscopic examination of frond sections must be made.
