furnishes an inferior qualitv. T. Asamnica is a stronger-grow- 

 ing species, whose quality seems to be as coarse as its ap- 

 pearance. These plants ibrra pretty evergreen shrubs ; they 

 are half-hardy, blooming about as large as pear-blossoms ; 

 and their treatment is like that of the Camellia. They are 

 propagated by cuttings, struck from the last year's wood, 

 with two joints, one put underground and one above — the one 

 to root, the other to branch ; but as these are not wanted in 

 great number in England, being only grown for curiosity, 

 the ends of shoots are taken so as to form a pretty little 

 plant directly it grows. They are also raised from seed by 

 sowing in pans, and placing them in the greenhouse till they 

 come up, when they may be first pricked out three or four 

 in a pot, and then potted one in a pot, which has to be 

 changed to lari^er ones as they grow. 



THERMOPSIS. [LeguminosEe, § Papilionaceae.] T. 

 fahacea is a pretty hardy perennial worth cultivating. It 

 should have a light rich soil, and generally produces ripe seeds, 

 by which it is best propagated : the seedlings take a couple 

 of years to grow to a blooming size. 



THIBAUDIA. [Vacciniaceae.] Evergreen shrubs, some 

 of great beauty, cultivable in a greenhouse. Fibry peat and 

 loam. Cuttings in sand of half-ripe shoots in heat under a 

 bell-glass will root freely. 



THOMASIA. [Byttneriaceae.] Greenhouse hard-wooded 

 evergreen shrubs of a peculiar aspect, easily cultivated, and 

 forming a pretty variety in a mixed collection. They in- 

 crease by cuttings in sand under bell-glasses, and grow in 

 turfy peat soil, with about a third part of sandy loam added. 

 The plants should be rather closely topped and frequently 

 repotted while young, to encourage growth, and to produce 

 bushiness of habit ; but when a foot or so in height they 

 may be allowed to progress more slowly, and will flower 

 abundantly. 



THRIFT. See Armeria. 



THUJA. ARBOR-VIT.E. [Coniferse.] These are among 

 the best of evergreen shrubs for the shrubbery, or as specimen 

 plants on lawns. T. orientalis, the Chinese Arbor-vitse, is 

 well known, and is admired for its close cone-shaped outline. 

 T. occidenUdls, the American Arbor-viti3e, has the same habit.
