666 BOTANICAL LOCALITIES OE STATIONS. 



Among them may be noticed, Nettles, Docks, Borage, Henbane, Xanthium. 

 Here, also, have been placed some plants immediately connected with, the habita- 

 tion of man, such as Racodium cdlwre, a fungus found on wine casks. Some 

 plants, as Sempemmmt tectorum, select the roofs of houses. 



11. Plants growing in vegetable mould ; such as bog-plants, or those growing 

 on wet soil, so soft that it yields to the foot, but rises again ; and marsh plants, 

 growing in wet soil, which sinlcs under the foot and does not rise. To the former 

 class belong such plants as Pinguicula alpiiut and Primula fannosa j to the 

 latter, such as Menyanthes, bogbean, Comarvm, Bidens cernua. 



12. Forest plants, including trees which live in society, as the Oak, the Beech, 

 Firs, etc., and the plants which grow under their shelter, as the greater part of 

 the European Orchises, some species of Carez and Ordbanche. Some plants 

 especially grow in pine and fir woods, as Linncea borealis, and some Pyrolas. 



13. Plants of sterile places, found in barren tracts, by roadsides. This is a 

 heterogeneous class, and contains many plants of uncertain characters. Under it 

 are included the plants of uncultivated grounds, as those found in moors, where 

 Oalluna vulga/ris, common heather, and various heaths. Juniper, Andromeda, 

 and some species of Polytriclium occur. 



14. Plants of the thickets or hedges, comprehending the small shrubs which 

 constitute the hedge or thicket, as the Hawthorn and Sweet-brier ; and the herba- 

 ceous plants which grow at the foot of these shrubs, as Adoxa, Wood-sorrel, 

 Violets ; and those which climb among their numerous branches, as Bryony, 

 Black Bryony, Honeysuckle, Traveller's Joy, and some species of Lathyrus. 



15. Plants of the mountains, which De CandoUe proposes to divide into two

 covered with perpetual snow, and where, during the heat of summer, there is a 

 continued and abundant flow of moisture, as numerous Saxifrages, Gentians, Prim- 

 roses, and Rhododendrons. 2. Those inhabiting mountains on which the snow 

 disappears during summer, as several species of Snap-dragon, among others the 

 Alpine Snap-dragon, Umbelliferous plants, chiefly belonging to the genus Seseli, 

 meadow Saxifrage, Labiate plants, etc. 



0. — Plants Growing in Special Localities. 



16. Parasitic plants, which derive their nourishment from other vegetables, 

 and which, consequently, may be found in all the preceding situations ; as the 

 Mistleto, species of Orobanche, Ouscuta (Dodder), Loranthus, Eajfleda, and 

 numerous Fungi. 



17. Pseudo-parasitic plants, or Epiphytes, which live upon dead vegetables, as 

 Lichens, Mosses, etc., or upon the bark of living vegetables, but do not derive 

 much nourishment from them, as Epidendrmn, Aerides, and other Orchids, as 

 well as TiUandsia, Bromelia, Pathos, and other air-plants. 



18. Subterranean plants, or those which live under ground, or in mines and 

 caves, almost entirely excluded from the light, as Byssus, Tuber ciia/riwm, Truffles, 

 and some other Ciyptogamic plants. 



19. Plants which vegetate in Ihot springs, the temperature of which ranges 

 from 80° to 150° of Fahrenheit's thermometer ; as Vitex Agnus-castus, and seve- 

 ral Cryptogamous plants, as Ulva thermalis, the hot-spring Laver. 



20. Plants which are developed in artificial infusions or liquors, as various 

 kinds of Mucor, causing mouldlness. 



21. Plants growing on living animals ; as species of Sphwria and Sarcinula 

 and various other Fungi and Algaj. 



22. Plants growing on certain kinds of decaying animal matter ; such as 

 species of Onygena, found on the hoofs of horses, feathers of birds, etc., some 

 species of Fungi, which grow only on the dimg of animals, and certain species of
