Salt glands are secretory organs that occur in several angiosperm families including the Plumbaginaceae and Poaceae. They are particularly prevalent on the leaves of plants growing in saline habitats where by the secretion of ions, they prevent toxic levels of salts from accumulating in their tissues. Whether different species of halophytes containing morphologically disparate glands preferentially secrete different cocktails of ions is not known. This question was addressed by employing SEM and EDS to determine the morphology and elemental constituents of crystalline deposits over the salt glands of two species of salt marsh halophytes: Limonium scabrum (Thunb.) Kuntze (Plumbaginaceae) and Sporobolus virginicus (L.) Kunth (Poaceae).The two halophytes, collected from intertidal marshes and cultivated in a mixture of coarse sand and compost (3:1 by volume) were irrigated daily with tap water and fertilised every two weeks with full strength Hoagland’s nutrient solution. Plants were watered weekly for 3 months with 50 mol m−3 NaCl supplied as diluted sea water.

This chapter considers the range of wetland environments that existed in Anglo-Saxon England, and the uses to which they were put, using archaeological, documentary and place-name evidence. It demonstrates that the drainage schemes and canals of Roman Britain mostly fell into disrepair, and that as sea levels rose coastal wetlands once again became saltmarsh environments (over a time-scale that would have been perceptible to local communities). These landscapes were, however, rich in natural resources and in the Middle Saxon period the growing intensity of wetland management is reflected in the digging of drainage systems, changing the relationship between people and their environment. In the Late Saxon period this culminated in the reclamation of some, but not all, wetlands, a transformation of the landscape that would have profoundly affected the daily lives of the communities living there as new patterns of land-use – and therefore annual cycles of living and working – were introduced. Those intertidal marshes that remained were economically important as a source of salt production and rich grazing land.
