to form little bushy tufts, and in which the va- 

 riegated sorts, and the Silver Thyme and Lemon 

 Thyme particularly, form a very agreeable va- 

 riety. Tiie Lemon Thyme is also in much esti- 

 mation for its peculiar odoriferous smell. Soriie 

 of each of these sorts may also be potted, in or- 

 der to move occasionally to any particular places 

 as may be required, and under occasional shelter 

 in severe winters to preserve the plants more ef- 

 fectually in a lively state ; likewise some of the 

 Mastic Thyme. Spanish and Portugal Thymes 

 are also sometimes potted for the same purpose, 

 and to place under the protection of a garden 

 frame or green-house in winter, to continue 

 them in a more fresh and lively growth : and 

 sometimes some of the smaller Thymes are 

 sown or planted for edgings to particular beds or 

 borders for variety, such as the Lemon Thyme, 

 Silver-leaved and variesated sorts ; also occa- 

 sionally the Common Thyme; and all kept low, 

 close, and regular, by clipping them at the sides 

 and tops annually in the summer season. 



TICKSEED-SUN-FLOVVER. See Core- 

 opsis. 



TILfA, a genus containing plants of the or- 

 namental tree kind. 



It belongs to the class and order Polijnjulrta 

 Moiiogijnia, and ranks in the natural order of 

 ColumnifercE. 



The characters are: that the calyx is a five- 

 parted perianth, concave, coloured, almost the 

 size of the corolla, deciduous : the corolla has 

 five petals, oblong, obtuse, crenate at the tip : 

 the stamina have numerous tilaments, (thirty 

 and more) awl-shaped, length of the corolla : an- 

 thers simple: the pistillum is a roundish germ : 

 style filiform, length of the stamens : stigma a 

 blunt pentagon : the pericarpium is a coriaceous 

 capsule, globular, five-celled, five-valved, open- 

 ing at the base: the seeds solitary, roundish. 



The species arc : 1 . T. Europtea, European 

 Lime Tree ; 2. T. ylmerkaiut. Broad-leaved 

 American Lime Tree ; 3. T. puhescens, Pubes- 

 cent Carolina Lime Tree; 4. T. alha, White 

 Lime Tree. 



The first is a tall upright tree, with smooth 

 spreading branches thickly clothed with alternate, 

 petioled, heart-shaped, smooth, serrate leaves, 

 pointed at the end, oblique at the base, glau- 

 cous beneath, and the veins, where they branch 

 off from the nerve, being furnished with a tuft 

 of glandular wool, as in the Laurustinus : the 

 flowers, which are delightfully fragrant, espe- 

 cially at night, come forth in July, in umbels or 

 cymes, (from three to five together,) on long- 

 axillary peduncles, with a singular, oblong, 

 blunt, membranaceouSj pale, entire bracte, nearly 



as long as the peduncle, and attached to it for 

 about half its length, and falling off with it. It 

 is a native of Europe, &c. 



It is, though little used, a handsome tree, 

 having a smooth ta])er straight trunk, and the 

 branches forming a beautiful cone. The foliage 

 also is smooth and elegant : it grows to a very 

 large size, and affords good shade: it makes a 

 fine detached object in parks and open lawns, 

 planted singly : the branches are so tough as 

 seldom to be broken by the winds, and the 

 flowers have a delightful fragrance : the wood is 

 soft, but capable of being turned into light bowk 

 and dishes, &c. 



There are several varieties ; as the Nar- 

 row-leaved, the Broad-leaved, the Elm-leaved, 

 the Red-twigged, the Smooth Small-leaved, the 

 Smooth Large-leaved, the Soft Hairy-leaved, 

 the Wrinkled-leaved, and the Striped-leaved. 



The second species has the branches covered 

 with a dark brown bark : the leaves are large, 

 heart-shaped, ending in acute points, are deeply 

 serrate, and of a full green on their upper side, 

 but of a pale green and a little hairyon their under 

 side, standing upon long slender footstalks : the 

 petals are narrower, and have nectariums arrowing 

 to their base: the flowers do not appear till late in 

 July, a full month after the common sort. It is a 

 native of Virginia and Canada, and was brought 

 from New England by the name of Black Lime. 



The third is a tree of much smaller growth 

 than either of the former : the branches spread 

 more horizontally : the leaves are smaller, and 

 have a smoother surface; they are heart-shaped, 

 but the midrib runs obliquely to the footstalk, 

 so that one side of the leaf is much larger than 

 the other ; the edges are slightly serrate, and 

 their ends run out into long acute points : the 

 bunches of flowers stand upon long slender 

 footstalks ; the petals are narrow, and end in 

 acute points ; have each a narrow, ncclariuni 

 fastened to their base on the inside, standing 

 erect close to the petals : the flowers emit a 

 very fragrant odour, and come out towards the 

 end of July. It is a native of Carolina. 



The fourth species has the leaves snow-white 

 beneath, and the flowers as in the second sort, 

 but smaller. It is a native of North America, 

 or Hungary. 



Culture. — These trees may be increased bv 

 seeds, layers and cuttings. 



The seed, when ripe in the autumn, should 

 be beaten down, keeping the green-twigred and 

 red-twigged sorts separate; and be sown soon 

 after, or preserved dry and sound till sprino- ; 

 sowing it in a bed or border of common earth, 

 previously digging the ground, and dividinff it
