OF ORNAMENTAL EXOTIC PLANTS. 179 
C.lanata. Both plants are extremely ornamental and highly deserving of culture, as the flowers are not only extremely 
beautiful, but delightfully fragrant. The flowers of the variety are particularly interesting, from the colour of the 
blossoms being extremely rare in any species of Composite, the flowers in that order which have a white ray, 
haying, generally, a yellow disk. Indeed, Sir W. J. Hooker observes, that he “never before met with any having 
a white ray and a blue disk.” This very beautiful variety was raised by Mr. Morrison, gardener at Rosemount, 
near Belfast, in 1839. It is probable that the beautiful blue hybrid Cinerarias which are now so common in 
gardens have been raised from the seeds of this variety. 

OTHER SPECIES OF CINERARIA. 
C. TUSSILAGINIS L’ Herit. 
This is a handsome species, a native of Teneriffe, which was introduced in 1777, but having been soon lost, it 
was not again introduced till 1832. The beautiful C. Waterhousiana is said to be a hybrid between this species 
and C. cruenta. 
C. AURITA LP Herit. 
This species was introduced in 1777, and its flowers are rather more of a bluish purple than those of most of 
the other species. 
Many other species might be named, but those which have been above described, with their hybrids and 
varieties, are the kinds most generally found in greenhouses in Great Britain. Jt may be observed that many of 
the kinds are cross breeds, that is, raised from two hybrids, and these generally are much more beautiful than those 
which are raised from two species. It must also be observed that all the species and varieties above described are 
placed by modern botanists in the genus Senecio, and that the few species which are left in the old genus Cineraria, 
or Cape Aster, have rather small weedy-looking flowers, and are scarcely worth cultivating, particularly as, being all 
natives of the Cape of Good Hope, they require a greenhouse in the climate of Great Britain. 
GENUS II. 
HELICHRYSUM Dec. THE HELICHRYSUM. 
Lin. Syst. SYNGENESIA POLYGAMIA SUPERFLUA. 
Generic Cuaracter.—Flower head composed of numerous florets, } naked or with alveole or little hairs. Achenium not beaked, sessile, 
all of which are tubular, hermaphrodite, and five-toothed. Involucre | with the point of attachment terminal. Hairs of the pappus in one 
imbricate; scales scariose, the interior ones sometimes connivent, | row, rough but not feathered, sometimes free, sometimes connected 
sometimes radiating. Receptacle flat, without pale, either quite | equally at the base, or unequally joined or branched. 
Description, &c.—Perhaps few kinds of plants have been more confused than those in this genus and its 
allied genera, all of which are known by the popular English name of Everlasting, from the great length of time 
which their flowers remain uninjured after they are cut. Thus we find the plants now included in this genus 
distinguished in the works of the old botanists under the various names of Gnaphalium, Astelma, Xeranthemum, 
and Elichrysum, besides various other names which have been given to particular species by botanists who have 
wished to make these species into genera, but whose generic names have not been adopted by any botanical writers 
but themselves. In addition to these, De Candolle has made a new genus, called Aphelewis, out of some of the 
species of Helichrysum, and several other genera out of the old genus Gnaphalium. To avoid confusion, however,
