TREACLE-MUSTARD.—The names of French Mustard, Treacle-Mustard, and Treacle Worm-seed were given to the Erysimum cheiranthoides, the two last because, in mediæval times, the seed of this plant formed one of the seventy-three ingredients of the far-famed “Venice treacle,” a noted antidote to all poisons, believed to cure “all those that were bitten or stung of venomous beastes, or had drunk poisons, or were infected with the pestilence.” The origin of this counter-poison was the famous Mithridaticum, a preparation invented by Mithridates, king of Pontus. Andromachus added to this comparatively simple compound other ingredients, and especially vipers; changing, on that account, the name to Theriaca (from the Greek therion, a small animal). Dr. Prior tells us that this remedy, which was known in England originally as Triacle, was the source of many popular tales of sorcerers eating poison, and was retained in the London Pharmacopœia till about a century ago.
TREFOIL.—Among the Romans, the Grass crown made of Trefoil-leaves was esteemed a mark of very high honour. (See [Clover] and [Shamrock]).
TROLL-FLOWER.—The Globe-flower (Trollius Europæus) acquired the sobriquet of Troll-flower in allusion to the Trolls, who were malignant elves, and because of the plant’s acrid poisonous qualities. (See [Globe Flower]).
True-Love.—See [Herb Paris].
TUBEROSE.—The name Tuberose is simply a corruption of the plant’s botanical title Polianthes tuberosa. The Malayans call this sweet-scented flower “The Mistress of Night:” when worn in the hair by a Malayan lady, the blossom is an indication to her lover that his suit is pleasing to her. The Tuberose is a native of India, whence it was first brought to Europe towards the close of the sixteenth century. Its blossoms were at first single, but La Cour, a Dutch florist, obtained the double-flowering variety from seed. So tenacious was he of the roots, that even after he had propagated them so freely as to have more than he could plant, he caused them to be cut to pieces in order that he might have the pleasure of boasting that he was the only person in Europe who possessed this flower.
TULASI.—The Indian name of the Holy Basil (Ocimum sanctum) is Tulasi, under which appellation this sacred plant is worshipped as a goddess. (See [Basil]).
TULIP.—The origin of the brilliant and dazzling Tulip has been given us by the poet Rapin, who relates that the flower was a modest Dalmatian nymph, metamorphosed into a Tulip to save her from the importunities of Vertumnus. The story is thus told by the Jesuit poet:—
“Dalmatia claims the nymph, whom heretofore
A bright Timavian dame to Proteus bore;
To her the changing sire his gift conveys,
