ed from it by Linnezus, and formed 
into the genus Ipome'a. All the 
stove kinds may be made to flower 
in the open air, during summer, by 
contriving to keep the roots in heat ; 
and the hardy species only require 
sowing in the open ground. 
Cora Tree.—See Erytnri'na. 
Corsuta’r1a. — Mr. Haworth’s 
name for one of the new genera he 
formed out of Narcissus. 
Co/rcnorus. — Tilidcee. — Hot- 
house plants, not sufficiently orna- 
mental to be worthy of general cul- 
tivation. For the well-known Japan 
half-hardy shrub, generally called | 
Corchorus japonica, see Kernta. 
of the showy annuals formerly 
known by this name, are now call- 
ed Calliopsis, while most of the 
perennial species are still left in the 
former genus. For the difference 
between the derivation of the two 
names, and the culture of the an- 
nual species, see Cauuio/rsis. The 
perennial kinds are quite hardy ; 
but as they are tall-growing spread- 
ing plants, they require a great deal 
of room, and should be planted at 
the back of the borders. ‘They wiil 
grow in any common soil; and 
they are propagated by division of 
the roots. 
Coria‘ria. — Coridcee. — The 
myrtle-leaved Sumach. A dwarf 
shrub, with handsome leaves, and 
but small flowers. It will grow in 
any common soil, and is increased 
by division of the roots. 
Corms.—Tuberous plants, such 
“as the Crocus, the different kinds 
of Moreas, Babianas, and most of 
the Iridacee. Bulbs are of two 
kinds: those which have a number 
of coats, or skins, one within the 
ther, like the Hyacinth, which are 
ealled tunicated bulbs; those which 
consist of a number of scales, only 
attached at the base, like the Lily; 
but what are called Corms, are only 
a solid mass of feculent matter, and

CORNUS. 
| which modern botanists do not al- 
‘lew to be bulbs, but call under- 
ground stems. Corms do not re- 
quire taking up so often as bulbs, 
and when they are intended to re- 
main for several years in the ground, 
they should be planted from four to 
six inches deep at first; as every 
year a new Corm will form above 
the old one; and thus, if planted 
too near the surface, the Corm, in 
a few years, will be pushed out of 
the ground. ul 
Corn Cockie.—See Girua'co. 
CorNeELIAN CHERRY.—See Co’R- 
NUS. 
Corn Fiac.—See Guaprouus. 
Co/rnus.— Corndcee.—The Dog- 
' wood. Well-known shrubs, with 
|whitish or yellowish flowers, and 
dark purple berries. The species 
| are generally ornamental, from the 
shining red bark of their branches 
|in winter, and the intensely dark 
| purplish red of their leaves in au- 
'tumn. One species, Cornusmas, 
the Cornelian Cherry-tree, a native 
_of Europe, is remarkable for the 
large size and brilliant colour of its 
‘fruit; and another, a native of 
| North America, Cornus florida, for 
| the large size of its flowers, or rather 
| for that of the imvolucres, or floral 
leaves, which surround its flowers, 
/and which are of a brilliant white 
inside, and tinged with violet on the 
outside. All the species are remark- 
able for the hardness of their wood, 
and for the great length of time 
| which their seeds will remain in the 
| ground before they come up. On 
this account, when any kind of 
Cornus is to be raised from seed, 
| the seeds should be steeped in water 
| before sowing ; but, generally speak- 
ing, all the kinds are propagated by 
layers or cuttings of the old wood, 
both of which strike root freely. C. 
florida is generally grown in peat, 
in a sheltered situation, and thrives 
best where its roots are kept in the 
| shade; but unless its foliage is fully
