OTHER SPECIES OF GARDENIA. 
G. THUNBERGIA Zin. 
This is a very handsome species, with large, white, fragrant flowers, and shining leaves. It is said to be a 
native of the Cape of Good Hope, whence it was introduced in 1778. It is propagated by cuttings, but the young 
plants will not blossom till they are of a considerable size. It is easily distinguished from the other species by the 
limb of the calyx being tubular, and only open on one side. 
G. ROTHMANNIA Zin. 
A very handsome species, with a tree-like stem and a campanulate flower, which is white, spotted with dark red 
on the inside, and very sweet-scented. It is a native of the Cape of Good Hope, whence it was introduced 
in 1774. 
G. AMGNA Sims. 
This species is a native of China, whence it was introduced in 1823. The flowers are white, tipped with 
crimson, and very ornamental, and the stems are spiny. 


CHAPTER XXXVI. 
COMPOSIT A. 
EssentiaL CuaracTer.—Leaves without stipules, usually simple, | shaped ; in the latter case four or five-toothed, with a valvate mxstiva- 
but frequently much diyided. Florets collected in dense heads upon | tion. Stamens equal in number to the teeth of the corolla, and 
a common receptacle surrounded by an involucre. Bracts, when | alternate with them; the anthers cohering into a cylinder, Ovary 
present, stationed at the base of the florets, and called the pale of the | inferior, one-celled, with a single erect ovule. Style simple ; stigmas 
receptacle. Calyx superior, closely adhering to the ovary, and undis- | three. Fruit a small, indehiscent, dry pericarp, crowned by the limb 
tinguishable from it; its limb either wanting or membranous, divided | of the calyx. Seeds solitary, erect. Embryo with a taper inferior 
into bristles, palez, hairs, or feathers, and called pappus. Corolla | radicle. Albumen none. 
monopetalous, superior, usually deciduous, either ligulate or funnel- 
Dxscriprion, &c.—This is a very large order, but as most of the plants contained in it are natives of the 
temperate zones, there are but few greenhouse plants. In New Holland, especially, there are very few 
Composite. The order takes its name from each flower being composed of numerous florets. 
GENUS I. 
CINERARIA Lin. THE CINERARIA. 
Lin. Syst. SYNGENESIA POLYGAMIA SUPERFLUA. 
Generic Cuaracter.—Involucre deeply many-parted ; segments equal. Receptacle naked. Florets of the disk tubular, hermaphrodite; 
those of the ray ligulate, feminine. Anthers naked at the base. Pappus hairy, sessile. 
Description, &c.—Many of the species of the old genus Cineraria are included by modern botanists in the 
genus Senecio. Some of them are hardy plants, not remarkable for their beauty ; but others are among the most 
ornamental greenhouse plants we have. All these plants are either natives of the Canary Islands and Madeira, 
or hybrids raised in this country; and I have included them all in the genus Cineraria (which signifies ashes, and 
alludes to the whiteness on the underside of the leaves of some of the species), as they are generally known by that 
name in nurseries. There are some greenhouse species natives of the Cape of Good Hope, but they are now 
seldom grown.
