light more in, or make a greater return 
for, rich soil, than do these. There are 
upwards of a hundred varieties enume¬ 
rated in the florist’s catalogues, of every 
conceivable shade between white and 
dark purple, and many of them perfectly 
distinct. 
CROTALARIA (Linn.) Nat. Ord. 
Leguminostf. This is an extensive genus, 
and a few of its species are particularly 
beautiful; the greenhouse kinds are to 
be preferred; all of them grow readily 
in heath soil, the chief point in their 
culture being to observe that the young 
shoots are stopped once or twice in the 
early part of their growth, in order to 
counteract their natural tendency to 
grow upright, and become what is tech¬ 
nically expressed as “ long-legged.” 
CROWEA (Smith.) Nat. Ord. Rti- 
tacece. The two species of these plants 
are each lovely objects when in flower, 
which continues from the end of summer 
until the following spring. They should 
be grown in sandy peat well drained, 
have a full supply of water, and some 
slight shade from the sun in summer, 
with all the light and air possible in 
winter; the front shelf of the greenhouse 
is the most suitable place for them at 
the latter period, and by the side of a 
north wall in the hot months of the 
year; their flowers are rosy-purple. 
CUPHEA (Jacquin.) Nat. Or. Ly- 
thracea. An interesting genus, among 
which are to be found some highly orna¬ 
mental species, especially the recent in¬ 
troductions C. cordata and C. strigillosa. 
All of them succeed in a warm green¬ 
house, if potted in rough turfy loam, 
having a considerable quantity of sand 
added to it; the aimual species should 
be sown in heat early in the spring, and 
afterwards be treated in the manner usual 
with Balsams, or other plants of the 
same character; the flowers of the whole 
are extremely curious, and, in general, 
highly coloured. 
CUSCUTA (Linn.) Nat. Or. Cus- 
cutacea. These plants are deserving of 
attention from their parasitical charac¬ 
ter, as they will attach themselves to, 
and grow on, any other plant within 
their reach; their long twining stems 
emit an abundance of small fragrant 
flowers towards the end of summer. 
CYANELLA (Linn.) Nat. Or. Li- 
liaceai. Pretty greenhouse bulbs with 
white, blue, or yellow flowers; they 
grow readily in sandy loam and peat, 
and, like all other plants of the same 
order, require to have a resting season, 
which, for convenience, is generally de¬ 
ferred to the winter. 
CYCLAMEN (Linn.) Nat. Or. Pri- 
mulacea. These pretty bulbs are uni¬ 
versal favourites. All of them are hardy, 
delighting to grow in fibrous peat and 
decomposed leaf-mould; it is usual to 
cultivate them in pots for the sake of 
an early display of their lovely blossoms. 
They are readily multiplied from seed, 
and soon form blooming bulbs, which, 
under good treatment, continue to flower 
for a great number of years. We re¬ 
member to have seen a specimen of C. 
Jiederifolium , which, tradition said, had 
been cultivated by the immortal Lin¬ 
naeus ; it was then in robust health, and 
measured fourteen inches in diameter. 
CYCLOBOTHRA (Sweet.) Nat. Or. 
Liliacece. Beautiful hardy and half-hardy 
bulbous-rooted perennials, producing 
white or yellow flowers through the 
autumnal months; they grow well in 
sandy peat and loam, th'e tender species 
requiring the protection of a cold frame 
in winter. 
CYCNOCHES (Lindley.) Nat. Or. 
Orcltidaceai. The flowers of these plants 
bear a great resemblance to a swan when 
about to expand, the curved foot stalk 
taking the appearance of the neck, and 
the sepals and petals the wings and 
body of the bird; those of C. Loddigesii 
are spotted over with purplish-brown; 
but the flowers of the other species are 
entirely green, emitting a powerful but 
pleasant odour. The plants should be 
grown in pots of fibrous peat and moss, 
effectually drained, and otherwise treated 
in the manner of Brassias or other west¬ 
ern species. 
CYMBIDIUM (Swartz.) Nat. Or. 
Orchidacece. Another genus of Orchi¬ 
daceous plants, the flowers of which are 
copiously produced; on some species 
they are borne on pendent, and in others
