OF THE HALF-HARDY LIGNEOUS SPECIES OF THE ORDER 
LOBELIA‘CEZ. 
Tu'pa G. Don isa genus that contains some tall-growing herbaceous plants, natives of Chili, which 
might technically be considered as suffruticose ; because, in frames and green-houses, they retain 
their leaves, and do not die down during winter. Among these are T. salicifilia G. Don ; Lobélia 
Tipa Ait.; L. gigantéa Sims Bot. Mag., t.1785.; and L. salicifdlia Sw¢., which grows to the height 
of 16 ft., and makes a fine appearance in the open garden during the summer season. 
Lobélia arborea Forst. and L. supérba Cham. are natives of the Society Islands, superb plants 
which grow to the height of 12 ft. or 15 ft. ; but neither of them have been yet introduced. A shrubby 
species of Lobéléa from Valparaiso, in Knight’s Exotic Nursery, which has not yet received a name, 
appears as if it would grow 8 ft. or 10 ft. high; and, from its blue flowers, and deep green leaves, it 
would make a fine appearance against a wall. ;

HWALF-HARDY PLANTS BELONGING TO THE ORDER CAMPANULA'CER. 
Misschia airea Dumort.; Campanula atirea L., N. Du Ham., 3. p. 169., Bot. Reg., t.57.; is an 
evergreen’ suffruticose plant, growing to the height of 2ft. or more, in Madeira and Teneriffe, 
among rocks. It isan interesting shrub, which may be compared to a miniature tree. The stem 
is simple, rather fleshy, marked by the scars left by the falling of the leaves, but furnished with 
a crown of leaves at “top, and annual floriferous branches, which are disposed in‘a leafy pyramidal 
panicle. Leaves 3—6in. long, pale green, shining. Peduncles 1—3-flowered. Flowers erect. 
(Don’s Miil., iii. p 772.) From the habit of this plant, it is better adapted for conservative rockwork, 
than for being trained toa wall; but it may be tried in both manners; for, as it ripens seeds freely, 
the loss of plants can easily be supplied. 

CHAP. LXVII. 
OF THE HARDY LIGNEOUS PLANTS OF THE ORDER COMPO/SITE, 
GENERAL Characteristics. Flowers grouped in heads ; those in each head so 
disposed, and so environed by an involucre composed of bracteas, that cor- 
responds to a calyx, as to seem to constitute but one flower. The leading 
characteristics of the separate flowers are the following :— Ovary inferior, 
bearing on its top, in many, pappus of some kind. Corolla of 1 petal. 
Stamens 5, their anthers connate intoa tube. Style encircled by the tube; 
its top bifid, the portions of it extended above the tube. Ovary with 1 cell 
and 1 erect ovule. (Lindley’s Introd. to N. S.,and Lessing’s Synopsis Generum 
Compositarum, 1832.) The genera of this order that include hardy ligneous 
species are but few. The following characteristics of them are derived chiefly 
from Lessing’s Synops. Gen. Comp. The species are mostly natives of Europe 
and North America, and are all of the easiest propagation and culture in any 
common garden soil. 
Sr#uHe.i‘né Lessing. Flowers bisexual. Pappus with its segments branched, 
feathery, and in a single row. Rachis (receptacle) with chaffy projections. 
Involucre of many rows of bracteas. Heads purplish violet. Small shrubs, 
of the south of Europe. Leaves silkily tomentose beneath, entire. 
Ba’ccuaris R.Br. Sexes dicecious, or mostly so; with the pappus, in the 
male flowers, with its segments in a single row, in the female ones, with its 
segments in several rows; the corolla filiform. Where the sexes are 
not dicecious, the flowers of several rows in the exterior of the head are 
female : the rest Lessing has not characterised; but it would appear, from
