Geranium, Cardamine pratensis, mallows, Rubus, Oxalis, Epilobium, &c., but many species show more or less well-marked median symmetry (zygomorphism) as Euphrasia, Orchis, thyme, &c., and red, blue and violet are the usual colours.
They give an old-fashioned and restful appearance to a garden, and in the interstices charming little plants like thyme, Ionopsidium acaule, &c., are allowed to grow.
In this way such herbs as basil, marjoram, mint, sage, savory, thyme, balm, chamomile, horehound, hyssop and rue, as well as parsley, may be had throughout the season with almost the full flavour of the fresh herb.
WATER-THYME, known botanically as Elodea canadensis, a small submerged water-weed, native of North America.
Thymol has a strong odour of thyme and a pungent taste, and is freely soluble in alcohol, ether, chloroform or olive oil, but almost insoluble in cold water.
Is represented by Elodea canadensis or water-thyme,which has been introduced into the British Isles from North America.
Thyme and the small white dune-rose (Rosa pimpinellifolia) also grow in the dunes, and wall-pepper (Sedum acre), field fever-wort, reindeer moss, common asparagus, sheep's fescue grass, the pretty Solomon-seal (Polygonatum officinale), and the broadleaved or marsh orchis (Orchis latifolia).
THYMOL, C10H,40 or C 6 H 3 (OH) (CH 3) (C 3 H 7) [1: 3: 6 ], a methylisopropylphenol isomeric with carvacrol, is an aromatic substance found with the hydrocarbons cymene, C, 0 H, 4j and thymene, Collis, in oil of thyme (from Thymus vulgaris) and in other essential oils, e.g.
Morena, where the ladanum hush (Cistus ladaniferus) is specially abundant; those covered by the Lahiatae are known as tomiliares (from tomillo, thyme), and occur chiefly in the south, south-west and east of the table-land of New Castile.
Certain of these oils consist very largely of hydrocarbons; for example, those of turpentine, citron, thyme, orange, pine-needle, goldenrod (from Solidago canadensis) and cypress, while others contain as their chief constituents various alcoholic and ketonic substances.
