protection usually extended hardy green-house plants. 
Citrus.— (The generic name for the Orange tribe.') Some 
very petty dwarf varieties exist, well calculated for parlour- 
window culture; they bear fruit when less than a foot in height, 
are very easily managed, and quite ornamental. The Mandarin, 
or Chinese dwarf orange, and the Shaddock, or forbidden fruit, 
are figured in the Floral Magazine. 
Clematis (or Virgin's Bower). — Of this plant there are 
several species, which rank with green-house plants. Others 
which are hardy will be found on page 74. 
Cobea scandans, produces large bell-shaped flowers, of 
changeable hue. It is wonderfully rapid in growth, covering a 
large surface in a single season. It may be reared from seed, or 
by cuttings. 
Coronilla. — The C. glauca is an old green-house plant, and ! 
esteemed as an early and abundantly blooming shrub; producing 
clusters of yellow pea-shaped flowers. 
Correa ; so named in honour of the Abbe Correa de Serra,, 
for some years resident Portuguese Minister, to this country. 
There are several species, of which, probably, the most attractive 
is the speciosa figured in the Floral Magazine. 
Daphne. — The D. odora , is a well known tenant of the green- 
house ; its delicious odour, and constancy of bloom in winter, 
will ever make it attractive, however much we may be dazzled 
by flowers of more pretension. There are several other species, 
all deserving culture. 
Dracana ferrea. — The purple leaved Dragon plant, is a 
conspicuous object in a collection ; and serves to give variety 
and relieve the eye, when resting on a mass of green. 
Dianthus, (Carnation.) — See page 81. 
Epacis. — This plant has usually been considered somewhat 
difficult to manage ; it bears a strong resemblance, in habit and 
appearance, to the Heath ; is indigenous to New Holland from 
whence we have several species, producing beautiful tubular- 
shaped flowers, some with high colours, others pure white. 
Erica {Heath). — The catalogues of some European Nursery- 
men enumerate nearly five hundred species, and varieties of the 
Erica , principally natives of the Cape of Good Hope, Great 
Britain, and the south of Europe, &c. At some of the princely 
establishments in England, ranges of houses are occupied by 
this tribe alone; and an uninterrupted succession of flowers is 
maintained. Nothing can exceed the peculiar delicacy, almost 
retiring modesty of many of this genus ; but in this country it
