272 THE COMPOSITE FAMILY. aan 
Trachelium cerulcum, a south European plant of early cultivation in 
our flower-gardens, belongs to the same family. The Australian 
Goodenias, Scevolas, and their allies, often seen in our greenhouses, 
form a small family, which may almost be considered as a tribe of 
Campanulacee. 
I. LOBELIA. LOBELIA. 
Flowers in terminal racemes, usually leafless or nearly so. Corolla 
very irregular, more or less cleft on the upper side, with 5 lobes usually © 
forming 2 lips; the 2 upper lobes smallest, and erect or recurved: the 
3 lower ones spreading, and less deeply divided. Anthers united in a 
tube round the style, often hairy, or the 2 lower ones bearded at the 
top. 
A numerous genus, widely spread over the globe, and yet wanting in 
the greater part of the continent of Europe and northern Asia. Several 
North American species, with brilliant scarlet or purple flowers, as well 
as Cape or Australian ones with blue flowers, are much cultivated.

1. L. Dortmanna, Linn. (fig. 612). ee ater [.—An aquatic peren- 
nial, with tufts of nearly cylindrical, hollow, radical leaves 1 to 2 inches 
long, forming a dense green carpet at the bottom of the water, each 
tuft proceeding from a small thick stock, with filiform creeping 
runners. Flowering-stems erect and simple, rising about 6 or 8 inches 
above the surface of the water, almost leafless. Flowers pale blue, 6 
or 7 lines long, drooping, in a simple, loose terminal raceme. 
In shallows of lakes in northern Europe and America. Common in 
the lakes of Scotland and Ireland, and in the west of England, descend- 
ing as far south as Shropshire and South Wales. Fl. summer. [The 
leaves are formed of two tubes placed side by side, the flowering stem 
of one tube. ] 
2. L. urens, Linn. (fig. 613). Aerid L.-—Rootstock perennial, shortly 
creeping. with obovate or oblong radical leaves. Stems simple or 
slightly branched, erect, 1 to 14 feet high, bearing in the lower half 
lanceolate, slivhtly toothed leaves, and in the upper part a long slender 
raceme of erect, purplish-blue flowers, about the size of those of Z. 
Dortmunna. 
In moist heaths, in western Europe, from Andalusia to western and 
central France. In Britain, only in Dorsetshire and Cornwall. FF. end 
of summer and autumn. 
Il, JASIONE. JASIONE. 
Flowers blue, in small, terminal, hemispherical heads, surrounded by 
an involucre of several bracts. Calyx reduced to 5 very narrow, slender 
lobes. Corolla regular, deeply divided into 5 narrow segments. Anthers 
united at the base into a ring round the long club-shaped style. 
Besides our British species, the genus contains 2 or 3 allied peren- — 
nials, chiefly from the mountains of central southern Europe and 
western Asia. ‘The flower-heads of this genus show the nearest approach — 
to Compostte, from which the many-seeded capsules at once distin- 
guish it. 3
