Telephium: a plant with unbranched stalks, clothed with thick fleshy oval leaves, but producing no leaves immediately from the root: the flowers stand in form of umbels on the top of the stalk, and are followed, each, by from three to six pods full of small feeds: the root is irregular and knobby. It is indigenous in England, and perennial.
1. Crassula. Telphium vulgare C. B. Anacampseros, fabaria, & faba crassa quibusdam, Sedum Telpbium Linn. Orpine: with the leaves very slightly or not at all serrated: growing in hedges and moid shady grounds, and producing reddish or whitish pentapetalous flowers in June. The leaves have been sup-posed to be possessed of an anti-inflammatory power; but their virtues appear to be very inconsiderable, as they have no smell, and only an herbaceous mucilaginous taste.
2. Rhodiola five rofea: Rhodia radix C. B. Rofewort: with serrated leaves; growing in mountainous places, and producing yellow tetrapetalous flowers in the spring. The root of this species, of little smell when fresh, has when dry a very pleasant one, resembling, when the root is in perfection, that of the damask rose: in this odorous matter consists the medical virtue of the rhodiola, and its principal medical difference from the preceding species. Linnaeus observes, that when raised in gardens, it has not one hundredth part of the smell or virtue of that which is produced on its native mountains.
