4. Mixed up with the Lavender and Thrift were two plants which are superficially similar but are not closely related. These are the Sea Arrow Grass (Triglochin maritima) and the Sea Plantain (Plantago maritima). The leaves of the Sea Arrow Grass grow in flattened groups look like Iris leaves but in fact each leaf is half cylindrical. The Sea Plantain leaves are rather flatter, but the best distinguishing feature is that they tend to arise in a rosette entirely different from the flattened origins of the Sea Arrow Grass. An occasional pink flower showed the presence of the Sea Spurney. The two species likely to be found in salt marshes can be distinguished by their seeds. The one we found was Spergularia media which we recog- nised by the circular wing around all the seeds. The other one which can be found is Spergularia marina which only has a few of its seeds winged. Early in the year the only flower that is in bloom on a salt marsh is the Scurvy Grass. This plant was once used by sailors to protect them from the disease caused by lack of vitamin C. In fact three species of Scurvy Grass are to be found on the Essex Marshes. The commonest one, which we found, is the Long Leaved Scurvy Grass (Cochlearia anglica) Its lower leaves are described as cuneate at the base, which means that they look like the base of a traditional kite. We did not find
