the " noli-me-tangere " pictures in Eoman Catholic coun- 

 tries ; Impatiens Noli me tangere, L. 



TOUCH-WOOD, a fungus imported from Germany, and 

 apparently called for that reason Dutch-wood, 



Boletus igniarius, L. 



TOWER-CRESS, from its having been found growing upon 

 the tower of Magdalen College, Oxford. Its Lat. specific 

 name, turrita, expresses a pyramidal habit of growth, and 

 seems to have been given to it as a translation of its trivial 

 English name, in mistake of its intended meaning. 



Arabis Turrita, L. 



TOWER-MUSTARD, from the tapering growth of the in- 

 florescence something in the form of a Dutch spire, " om 

 de spits torrewijse oft naeldewijze ghewas van de steelkens,"

TOWN-CRESS, A.S. tun-ccerse, a cress grown in a tun, or 

 enclosed ground, as contrasted with the water- and other 

 wild cresses. Tun seems usually to have meant, as in Ice- 

 land at the present day, a close or pasture in connexion 

 with farm buildings. So in Wycliffe's N. Test. (Luke 

 xiv. 18) : "I have bought a toune." It is still retained in 

 this sense in that very interesting and only half-explored 

 magazine of antiquities, the nomenclature of our fields ; 

 and met with occasionally as Tun-mead. It is also the Du. 

 luin, a garden. Lepidium sativum, L. 



TOY-WORT, from the little imitations of purses that it 

 bears, Capsella Bursa, DC. 



TRAVELLER'S JOY, from the shade and shelter that it 

 affords by the bowers it forms in roadside hedges, 



Clematis Vitalba, L. 



TREACLE-MUSTARD, or -WORMSEED, from its being used 

 among 72 other ingredients, in making " Venice treacle," a 

 famous vermifuge and antidote to all animal poisons, and 

 one that was in great vogue during the Middle Ages ; Du. 

 triakel, Off. L. theriaca, from. Gr. Brjptov, a small animal.
