88 THE LIME FAMILY, [ Tilia. 
cated but not twisted in the bud; the stamens free or shortly 
united into several bundles; the anthers 2-celled, and the 
carpels more cempletely consolidated into a several-celled 
ovary. 
I, TILIA. LIME, 
Trees with alternate leaves, deciduous stipules, and small cymes of 
flowers on an axillary peduncle, to which is attached a long, leaf-like bract. 
Sepals 5, valvate in the bud. Petals 5. Stamens numerous, very shortly 
cohering in several clusters, Ovary globular, 5-celled, with 2 ovules in 
each cell, attached to the inner angle. Style single, with a 5-toothed 
stigma. Fruit, a small globular nut, containing 1 or 2 seeds. 
A genus of very few species, widely distributed over the temperate zone 
of the northern hemisphere, where it is the only representative of the 
family. 
1, Z. europeea, Linn. (fig. 200). Common Lime, Lime-tree.—A hand- 
some, long-lived tree, attaining sometimes as much as 120 feet in height, 
but generally not above half that size. Leaves stalked, broadly heart- 
shaped or nearly orbicular, often oblique, and always pointed, serrate on 
the edge, glabrous above and more or less downy underneath, especially 
in the angles of the principal veins. Peduncles hanging amongst the 
leaves, bordered or winged halfway up by the long, narrow, leaf-like bract. 
Flowers sweet-scented, of a pale whitish-green. Nut downy when young, 
but often glabrous when ripe. 
In woods, over nearly the whole of Europe, except the extreme north, 
and extending eastward across Russian Asia to the Altai. Much planted 
in Britain, and probably truly wild in southern and western England. #7. 
summer. It varies much in the size of the leaves, in the degree of down on 
their under surface and on the fruits, in the greater or less prominence of 
the 5 filiform ribs of the fruit, etc. The truly indigenous form in northern 
Europe is always a small-leaved one. The large-leaved variety which we- 
commonly plant (Z. qrandifolia, Ehrh.) is of south _Huropean origin, with 
the leaves still further enlarged by cultivation. Some North American 
species are also frequently planted. [The Limes are very puzzling, and no 
two authors are agreed as to their specific limits. The only certainly indi- 
genous British one is Z. parvifolia, EKhrh., with glabrous twigs, small 
leaves glaucous beneath, and downy crustaceous globose or ellipsoid faintly 
ribbed fruit. Then there is the possibly indigenous 7’. platyphyllos, Scop. 
(T. grandifolia, Ehrh.), with hairy twigs, leaves large and downy beneath, 
and obovoid or globose fruit with prominent ribs, said to be a native of west 
England. Lastly the 7. vulgaris, Hayne (7. intermedia, De.), commonly 
planted, with glabrous twigs, leaves pubescent in the axils of the nerves 
beneath, and a woody pubescent fruit, not ribbed when ripe]. 
XX. GERANIACEZ. THE GERANIUM FAMILY. 
Annual or perennial herbs, or in exotic species, low shrubs, 
with opposite or rarely alternate leaves, usually more or less 
divided or compound, toothed, and furnished with stipules. 
Flowers regular in the principal British genera, irregular in
