1102. Earthy soils are such as emerge above the water and constitute the surface of the habitable globe, that is every where covered with vegetable productions. Plants affecting such soils, which comprise by far the greater part of the vegetable kingdom, are denominated terrestrial, being such as vegetate upon the surface of the earth, without having any portion immersed in water, or requiring any further moisture for their support beyond that which they derive from the earth and atmosphere. This division is, like the aquatics, distributed into several subdivisions, according to the peculiar situations which different tribes affect. Some of them are maritime, that is, growing only on the sea-coast, or at no great distance from it, such as Statice, Glaux, Samolus, samphire, sea-pea. Some are fluviatic, that is, affecting the banks of rivers, such as Lythrum, Lycopus, Eupatorium. Some are champaign, that is, affecting chiefly the plains, meadows, and cultivated fields, such as Cardamine, Tragopogon, Agrostemma. Some are dumose, that is, growing in hedges and thickets, such as the bramble. Some are ruderal, that is, growing on rubbish, such as Senecio viscosus. Some are sylvatic, that is, growing in woods or forests, such as Stachys sylvatica, Angelica sylvestris. And, finally, some are alpine, that is, growing on the summits of mountains, such as Poa alpina, Epilobium alpinum, and many of the mosses and lichens.
