TILE-ROOT. See Geissorhiza. 
TILESIA. A synonym of Wulffia (which see). 
TILIA (the old Latin name for the Lime, used by 
Virgil and Pliny). Lime-tree; Linden. Orp. Tiliacee. 
This genus includes about eight species of ornamental, 
lofty-growing, hardy, stellate- or simply-pubescent trees, 
inhabiting the temperate regions of the Northern hemi- 
sphere. Flowers white or yellowish; sepals five; petals 
five, naked or furnished with petaloid scales on the 
inside; stamens numerous, free or irregularly disposed 
in bundles; bract of the peduncle leaf-like, adnate for 
half its length ; cymes axillary or terminal. Fruit globose, 
nut-like, indehiscent, one or two-seeded. Leaves often 
obliquely cordate, serrated. Several species are grown in 
this country, one being a native. The flowers contain 
a quantity of honey, and are consequently haunted by 
bees. Russian Bass or Bast Mats, so well known to 
gardeners, are prepared from the inner bark of various 
species. The smooth, light, delicately-white, and uniform 
wood of T. platyphyllos and T. vulgaris is in great demand 
by carvers, turners, and musical instrument makers. 
Culture, §c. A good, loamy soil is suited to the require- 
ments of Limes. In dry situations, the species never 
attain a large size, and they lose their leaves earlier — 
than any other tree. Being a tree of the plains, rather 
than of the mountains, the Lime does not appear suitable 
for very exposed situations. Propagation is usually 
effected by layers, which are made in the nurseries, in 
autumn and winter, and become rooted, so as to admit 
of being taken off, in a year. Seeds are seldom 
ripened in this country; when obtainable, they should 
be sown immediately after being gathered, but the raising 
of plants by this means is an exceedingly slow process. 
Du Hamel states that “the French gardeners, when 
they want a supply of young Lime-trees, cut over 
an old one close by the surface of the ground, which 
soon sends up a great number of shoots: among these 
they throw in a quantity of soil, which they allow to 
remain one, two, or three years; after which they 
find the shoots well rooted, and of a sufficient height 
and strength to be planted at once where they are finally 
to remain.” This mode is still practised in France and 
Belgium, both with the Lime and the Elm. The Lime-tree 
bears transplanting when of a considerable size; but when 
grown for this purpose, it should be taken up and re- 
planted every two or three years. Trees that have stood 
some years without being removed should have the roots 
cut round, at from 3ft. to 4ft. from the stem, a year before 
transplanting, in order to stunt the growth, both of the 
head and roots, and to induce the production of smaller 
roots and fibres. The different cut-leayed and variegated 
forms are usually increased by grafting on strong plants 
of any of the common species. _ 
Insects, fc. Of foes to the Lime-tree, only a few do so 
much injury as to call for detailed notice here. The bark 
and wood are liable to attacks by Beetles, though 
healthy trees seldom suffer thereby. The caterpillars of 
several kinds of Moths, most of them small, frequently 
disfigure the leaves by drawing them together by webs, 
or rolling them to form tubes, and by eating large 
holes in them. The more destructive species belong 
to the Winter Moths, the females of which either have 
no visible wings, or have them so small as to be useless 
(see and Winter Moth). Their ravages may 
be lessened by shaking the branches, and collecting the 
-= caterpillars when they drop from their tubes; or, yet more 
effectually, by interposing an obstacle, e.g., a belt of tar, 
in autumn and winter, round the foot of the tree, to 
prevent the ascent of the female moth to lay her eggs. _ = 
Lime-trees are very liable to be injured by the growth 
of galls on the younger parts. A Gall-midge (Cecidomyia 
floricola) often makes galls on the branches or leaf- 
stalks, in the form of swellings about the size and 
form of a small pea, in the centre of which the larve may
