CALANTHE ( it. Brown.) Nat. 
Or. Orcliidacem. Remarkably handsome, 
free-flowering plants ; should be grown 
in pots of fibrous peat, well drained, and 
allowed the most airy part of the stove. 
C. veratrifolia, white, C. masuca, purple, 
C. bicolor, yellow, and C. plantaginea, 
rose colour, are the most ornamental. 
CALCEOLARIA (Linn.) Nat. Or. 
Scrophulanacece. BotanicaHy considered 
this is an extensive and beautiful genus 
of dwarf shrubs, herbaceous plants, and 
annuals; but rich as it is in native beauty, 
the constant accession of hybrids and 
seminal varieties make it almost without 
a rival. The culture of all the perennial 
kinds may be reduced to this : grow them 
in light rich loamy soil, and give them 
so much protection as will ensure them 
from frost, but avoid the application of 
fire heat as much as possible. In rais¬ 
ing new varieties, the several kinds de¬ 
sired to improve should be cross-impreg¬ 
nated one with another, and the seed 
thus obtained should be sown as soon 
as ripe, and the product potted se¬ 
parately into small pots as soon as 
they can be handled, keeping the young 
•plants in a pit through the winter, and 
in the following Eebruary let them be 
placed into larger pots to bloom, at which 
time no better ornaments will be found 
for the greenhouse, as they will continue 
in perfection from the middle of May 
till that of July; the inferior varieties 
make especial fine subjects for decorating 
the flower beds, their effect being highly 
pleasing when planted in masses. All 
the kinds are rather impatient of stag¬ 
nant moisture, therefore let the pots be 
well drained, plenty of air admitted on 
every favorable opportunity, and when¬ 
ever they are watered let them have a 
good supply that they may not require 
it again directly. 
CALENDULA (Linn.) Nat. Ord. 
Composite. It is only the annual species 
of these plants that are worth attention, 
and they are rather coarse, suitable, how¬ 
ever, for the- borders of shrubberies and 
similar places ; they may be sown where 
they are intended to remain, .and after¬ 
wards be thinned to about a foot from 
each other. The common yellow mari¬ 
gold is included in the genus. 
CALLA (Linn.) Nat. Ord. Aracece. 
Showy greenhouse, herbaceous plants, 
producing large white flowers; may be 
grown in any rich soil so that they 
receive an abundant supply of water 
through the summer ; increase is had by 
means of offsets. 
CALLICHROA (Eischer.) Nat. 0. 
Composite. The only species known, 
C. plcdyglossa, is an annual which should 
be grown by every one; it is a neat, 
dwarf-growing plant, producing numbers 
of rich golden blossoms; the seeds should 
be sown in March on a gentle heat, and 
the young plants placed where they are 
to bloom about the end of May: it is a 
native of California. 
CALLIOPSIS (De Candolle.) Nat. 
Ord. Composites. This is a genus of 
showy annuals, separated from Coreopsis; 
they are of hardy character, requiring 
only to be sown in rich earth about the 
end of March, and afterwards thinned 
out; those taken up for the purpose may 
be transplanted and will afford a later 
bloom; they usually attain a height of 
about three feet, and consequently shoidd 
be sown some distance from the margin 
of the bed. If a very early bloom is 
desired, a few plants may be raised on 
heat and transplanted in May. 
C ALLI ST ACHY S (Yentenat.) Nat. 
Ord. Leguminosce. Greenhouse plants 
from New Holland, producing beautiful 
yellow flowers ; grow readily and with¬ 
out trouble under ordinary treatment; 
they delight in a mixture of peat and 
loam, and cuttings strike freely in sandy 
sod, covered with a glass. 
CALLISTEMMA (R. Brown.) Nat. 
Ord. Compositce. This genus contains 
two species, C. indicum and C. hortensis, 
the wed blown China Aster, the varieties 
of which are so universally grown; the 
seed shoidd be sown in March on a 
gentle heat for the eariiest bloom, and 
others may be sown a week after in the 
open ground to afford a succession of 
flowers ; the first, after being gradually 
inured to the open air, may be removed 
to their destined places as soon as danger
