TURPENTINE-TREE. 



322 



ULEX, 



Avithered, tlie bulbs are taken up 

 and laid on shelves to dry ; after 

 ■which the leaves, if any remain on, 

 are removed, and the fibrous roots, 

 which will have withered up, are 

 rubbed off, and the bulbs are put 

 into a box, divided into compart- 

 ments, so as to keep the named 

 sorts apart till the season for re- 

 planting, which is the last week 

 in October or the first in November. 

 A fresh bed should be made for 

 Tulips every year, or the soil of the 

 old bed should be changed ; as the 

 exudations from Tulips poison the 

 ground for other plants of the same 

 kind, though they are suitable for 

 other crops. The usual rotation in 

 Holland is, Tulips, Polyanthus, 

 Narcissus, Crocuses, and Hyacinths. 

 Mr. Groom, ofClapham, is the prin- 

 cipal Tulip-grower in the neighbour- 

 hood of London ; and he has an ex- 

 hibition of them every year in May.

DRON. 



Tu'na. — One of the kinds of 

 Prickly Pear or Indian Fig. — See 

 Opu'ntia. 



Tu^PA. — Loheliacece. — The new 

 name for the large upright-growing 

 kinds of Lobelia, with scarlet 

 flowers. 



Tupelo-tree. — N^ssa sylvdtica. 



Turmeric. — Curcuma. — Scitami- 

 neous plants v/ith very showy flowers, 

 natives of the East Indies, which 

 require a stove in England. They 

 should be grown in light rich earth, 

 and they are propagated by ofisets. 



Tu'rxera. Turnerdcece. 



Stove shrubs and herbaceous plants 

 with yellow flowers, some of which 

 bear a slight resemblance to those 

 of the Thunbergia. They should be 

 grown in light rich soil, and they 

 are propagated by cuttings, or by 

 seeds, which they ripen freely. 



Turpentine-tree. Pistacia 



Tercbmthus. — It must be observed. 



however, that common turpentine is 

 procured from the different trees of 

 the Pine and Fir tribe. 



Tussila'go. — CoviposikB. — The 

 Colt's-Foot or Butter Bur. — Some of 

 the species are pretty and worth cul- 

 tivating, particularly T. frdgrans. 

 They will all grow in any gar- 

 den soil ; but are very troublesome 

 to keep within bounds, from the 

 immense number of suckers that 

 they send up from their roots. 



Tutsan. — See Andros^'mum and 

 Hype'ricum, 



I Tyd^a amabilis is the new name 

 for A chimenes picta. 



T y'pha. — TypTdnce. — Cat' s-Tail 

 Rush. — Aquatic plants, suitable for 

 growing on the borders of ponds, and 

 made pieces of water, to hide the 

 boundary. 



TT^LEX. Leguminbsce. — The 



^ Furze. — An erect evergreen 

 shrub with yellow flowers, v/hich 

 I are produced nearly all the year. 

 The double-blossomed Furze is very 

 handsome, and makes a beautiful 

 hedge. When it is employed for 

 this purpose, a bank of earth should 

 be raised three or four feet high, 

 and wider at the bottom than at 

 the top, and the cuttings should be 

 planted in adrill along the ridge. The 

 soil should be somewhat sandy, and 

 if there be plenty of room the plants 

 should be left to nature, tohangdown 

 loosely over the bank, and they should 

 never be pruned, except to cut oiit 

 the dead wood. U. nana grows 

 generally on very poor gravelly soils, 

 and seldom exceeds two feet in 

 height ; while U. eurojyce'a, the 

 common kind, in favourable situ- 

 ations, will grow ten feet high. U. 

 stricta, the Irish Furze, has no 

 spines, and it grows straight up- 

 right to the height of eight or ten 

 feet. It requires a moist rich soil ;
