204 THE UMBELLATE FAMILY.  [Physospermum. 
XXXVI. CORIANDRUM. CORIANDER. 
Fruit globular, not readily separating into the two carpels, crowned by 
the conspicuous teeth of the calyx, the ribs scarcely prominent, and no 
vittas. 
A single species, very distinct in the form of the fruit. 
1, C. sativum, Linn. (fig. 454). Common Coriander.—An erect, 
branching, glabrous annual, 1 to 13 feet high, emitting a very disagreeable 
smell when rubbed. Lowest leaves once or twice pinnate, with broadly- 
ovate or cuneate, deeply-cut segments; the others more divided, with linear 
segments, few and slender in the uppermost leaves. Umbels terminal, 
rather small, of 5 to 8 rays, without general involucre, and only a few small 
slender bracts to the partial ones. Flowers white, the outer petals larger. 
Fruits about 2 lines long. 
A native of the Levant, long since cultivated in Europe, and occasionally 
spreading as a weed ofcultivation. Said to be established as such in some 
of the southern and eastern counties of England. 7. summer. 
XXXVI. ARALIACEA. THE ARALIA FAMILY. 
Shrubs, trees, or climbers, rarely herbs, differing from most 
Umbellifere in their simple (solitary or paniculate) umbels, and 
more generally in their fruit more or less succulent, consisting 
often of more than 2 (from 2 to 10) carpels, which do not sepa- 
rate so readily asin Umbelliferw, usually forming a single berry, 
or, more strictly speaking, a berry-like drupe, containing as 
many one-seeded nuts as there are carpels, The styles also are 
sometimes united. 
A considerable Order, widely spread over the warmer regions of the 
globe, represented in Europe by a single species, Some species of Aralia 
are also occasionally cultivated in gardens, 
I. HEDERA. IVY. 
Petals not cohering at the top, valvate in the bud. Cells of the ovary 
5 or 10. Styles short, usually cohering in a single mass. 
A genus, as now limited, containing only a single Australian species, 
besides the British one. | 
1. H. Helix, Linn. (fig. 455). Common Ivy.—A woody, evergreen 
climber, when wild the lower, slender branches spread along the ground, with 
small leaves, whilst the main stems climb up trees, rocks, or buildings to a 
great height, adhering by means of small rootlike excrescences, Leaves thick 
and shining, ovate, angular, or 3- or 5-lobed ; those of the barren stems usually 
much more divided than the upper ones. Flowering branches bushy, pro- 
jecting a foot or two from the climbing stems, each bearing a short raceme 
or panicle of nearly globular umbels. Flowers of a yellowish-green. Borders 
of the calyx entire, scarcely prominent, about half-way up the ovary. 
Petals 5, broad and short. Stamens 5. Styles united into a single very 
short one. Berry smooth and black, with from 2 to 5 seeds, the albumen 
deeply wrinkled. 3
