The Norway Maple, A. platano eds afd A. Monenesslatnon from eastern 
or southern Europe, the sugar Maple (A. saccharatum) from North 
America, and some other exotic true Maples, besides the ash-leaved 
Maple, forming the genus Negundo, from North America, may be met 
with in our parks and plantations. 
1. A. campestre, Linn. (fig. 221). Common M.—When full-grown, a 
rather handsome, round-headed, though not very tall tree, with a dense 
dark-green foliage, but, as it is of slow growth and flowers when young, 
it is often seen as a small scraggy tree, or mere bush, in our hedges. 
Leaves on slender stalks, 2 to 3 inches broad, divided to about the 
middle into 5 broad, usually obtuse lobes, entire or sinuate, glabrous 
above, often downy underneath. Flowers few, on slender pedicels, in 
loose, erect corymbs, shorter than the leaves. Carpels downy or rarely 
glabrous, the wings spreading horizontally, so as to form together one 
straight line. 
In European woods, extending eastward to the Caucasus, and north- 
ward to southern Sweden. In Britain, abundant in southern England, 
and apparently truly indigenous as far north as Cheshire and the 
Tyne, rare in the wild state in Ireland. fl. spring. 
2. A. Pseudo-platanus, Linn. (fig. 222). Sycamore.—A much hand- 
somer and freer-growing tree than A. campestre, the leaves larger, with 
more pointed and toothed lobes, not unlike those of a Plane-tree. 
Flowers in loose, oblong, hanging racemes. Wings of the carpels 
nearly parallel, or diverging so as to form a right angle, not spreading 
into one straight line. 
A native of the mountains of central Europe and western Asia, 
naturalised in Britain. FJ. spring. 
XXII. AQUIFOLIACEA. THE HOLLY FAMILY. 
A small Order, widely spread over the globe, limited in 
Britain to a single genus, from which the few exotic ones 
differ sh¢ghtly in the number of parts of the flower and fruit. 
They nearly all approach Celastracee, but have the petals 
usually very shortly united into a monopetalous corolla, and 
the stamens inserted on its base, without any fleshy disk round 
the ovary. 
I, ILEX. HOLLY. 
Shrubs or trees, with alternate leaves, and small flowers in axillary 
clusters. Calyx of 4 or rarely 5 small teeth. Corolla regular, deeply 
divided into as many segments or petals. Stamens as many, inserted on 
the corolla, and alternating with its segments. Ovary sesséle, 4-celled, 
with one pendulous ovule in each cell, and crowned by 4 minute sessile 
stigmas. Fruit a berry, or rather a small drupe, including 4 stones or 
nuts, each containing a single seed. 
The species are numerous in the warmer parts of the northern hemi-
