from frost is past: the soil for them can¬ 
not be too rich. On this and selecting 
an open situation rests all the art of ob¬ 
taining line dowers. English gardens 
are supplied annually with a great quan¬ 
tity of seed from the Continent, the Bel¬ 
gian dorists bestowing much pains on 
the growth and selection of seeds from 
these plants. 
CALLISTEMON (II. Brown.) Nat. 
Order Legiminosec. Several species of 
Callistemon are particularly worthy of 
the eidturist’s care, being highly orna¬ 
mental to the greenhouse collection; 
those most deserving are such as li¬ 
near is ^ rigidus, speciosus, and viminalis 
They grow with freedom in a mixture of 
equal parts loam, peat, and sand; and 
are propagated by cuttings treated in 
the usual way. 
CALOCIIILUS (Brown.) Nat. Ord. 
Orchidacece. Yery pretty tuberous-root¬ 
ed Orchids of the terrestrial class; they 
may be grown in a good greenhouse in 
pots of dbrous peat and rotten wood, 
with a moderate supply of water in the 
growing season, and but very little in 
winter; the sepals of the dowers are pale 
green and the lip is purple. The species 
are derived from New Holland. 
CALOCHOBTUS (Pursh. ) Nat. 
Ord. Liliaccee. Beautiful plants, but 
much neglected; the roots may be planted 
either in a south border or in a frame : the 
soil should be sandy peat, strengthened 
with the addition of a portion of loam;’ 
they dower in the summer and autumnal 
months, and in winter the bidbs should 
either be taken out of the ground or 
properly projected from both frost and 
excessive wet; their dowers are white, 
purple, or yellow, most of them richly 1 
spotted. 
CALOPHANES (D. Don.) Nat. Or. 
Acanthaceai. A dne, hardy, herbaceous 
plant from California; the colour of its 
dowers is a lively blue, and the plant 
grows rapidly in prepared ground com¬ 
posed of peat and loam; increase is had 
by parting the roots. 
CALOSTEMMA (Brown.) Nat. Or. 
Amaryllidacece. Pretty, bulbous species 
from New HoUand, producing numerous 
white, yelloAv, or purple dowers; they 
grow readily in pots of peat and loam, if 
placed in a common frame, and are care¬ 
fully watered in dry weather. 
CALOTHAMNUS (Labillardiere.) 
Nat. Ord. Myrtaceae. Handsome green¬ 
house plants, with brilliant scarlet dowers 
and rich foliage. Eor culture see Bur- 
CHELLIA. 
CALOTEIS (B. Brown.) Nat. Ord. 
Compos’dee. A pretty, herbaceous plant, 
from New Holland; will grow in any 
rich soil, but requires the protection of 
'a greenhouse or good pit through the 
winter; the dowers are blue, and the 
leaves singularly wedge-shaped. 
CALOTBOPIS (Brown.) Nat. Ord. 
Asclepiadaceee. There are but two spe¬ 
cies, each of them beautiful and well, 
deserving to be grown for their short 
white dowers; the plants are evergreen 
dwarf shrubs, requiring to be grown in. 
a mixture of peat, loam, and rotten ma¬ 
nure, and to have an airy situation in 
the greenhouse ; young plants are most 
ornamental, and are easily obtained from 
cuttings struck in sandy soil on a gentle 
bottom heat, or from seeds treated in. 
the same manner. 
CALTHA (Linn.) Nat. Ord. Ra- 
nuncidaceee. Showy, herbaceous plants, 
suitable for the shaded sides of borders 
in the dower garden, as they delight in 
a moist situation, though they do not 
refuse to grow in almost any aspect; 
their dowers are yellow, except those of 
one species, C. biflora, which are white ; 
increase is generally had by division of 
the roots. 
CALYPSO (Salisbury.) Nat. Ord. 
Orchidaceee. An interesting little Or¬ 
chidaceous plant of the terrestrial class, 
nearly hardy, or requiring merely the 
protection of a frame during the winter; 
it grows best in light rich loam, if well 
drained by interspersing pieces of free- 
stoneandbrokenpotsthrough the soil;thc 
sepals and petals are brown, and the lip 
a bright rose colour;the plant is increased 
by offsets of the underground tubers. 
CALYPTBION (De Candolle.) Nat. 
Ord. Violaceee. A pretty climbing spe¬ 
cies, should be potted in loam and peat, 
and grown in the stove; it is propagated 
from seeds.
