showy, fragrant, and do not require any 
particular care in their management; in¬ 
crease is rapidly effected by cuttings. 
BULBOCODIUM (Wild.) Nat. Or. 
Melanthacecs. Very handsome, hardy 
bulbs, bearing purple flowers, and well 
deserving attention; they should be 
grown in sandy peat soil, and carefully 
watered in dry weather. B. vernum is 
one of our earliest flowers, blooming in 
February, the other species B. versicolor 
flowers towards the autumn. 
BURCHELLIA (R. Brown.) Nat. 
Order Cinchonacece. Ornamental green¬ 
house plants, which should be grown in 
rough sandy peat, and be carefully watered 
to induce them to flower well. B. ca- 
pensis is perhaps the best, and when well 
grown produces numerous heads of scar¬ 
let heath-like flowers; they are propa¬ 
gated by cuttings of the half-ripened 
wood struck in sand on a very moderate 
bottom heat. 
BURLINGTONIA (Lindley.) Nat. 
Ord. Orchidacece. Curious and very 
handsome epiphytes, which require to be 
fastened to rough billets of wood, and 
to be surrounded with a high and moist 
temperature while growing; increased 
by separation of the pseudo-bulbs. 
BUTEA (Roxburgh.) Nat. Order 
Leguminosve. There are three species of 
these plants known, all of them truly 
splendid; but very scarce in collections, 
the more remarkable as they have been 
known for a length of time, and are not 
difficult of either culture or propagation; 
the flowers are numerous, large, and of 
a brilliant scarlet; the plants grow with 
freedom in a common stove, if potted 
in rough peat and loam, and cuttings 
planted entire in small pots of light 
earth, such as sandy peat, and plunged 
in heat, root readily, the only care ne¬ 
cessary being to guard them from the 
effects of damp. 
BUTOMUS (Linn.) Nat. Ord. Bu- 
tomacece. B. umbellatus is one of the 
most beautiful of our native aquatics; it 
is found by the margins of rivers or 
other water, and grows to the height 
of about three feet, when it produces 
its umbclls of pretty pink flowers; the 
other species, latifolius, has white flowers; 
either of them are appropriate ornaments 
to pieces of water in any position. 
BYRSONIMA (Richard.) Nat. Or. 
Malpighiaceee. Handsome stove plants, 
bearing yellow, white, or pink flowers, 
and growing with the greatest luxuriance 
in any rich soil; they, are increased bv 
means of cuttings planted in sandy soil, 
covered with a glass, and plunged in 
heat. 
CACTUS (Linn.) Nat. Order Cac 
tacece. Formerly this was an exten¬ 
sive genus, containing many succulents, 
of various habits and characters, that 
are now separated into several distinct 
genera, as Cereus, Echinocactus, Me- 
locactus, Mamillaria, Opuntia, &c., and 
by some authorities the original genus 
is entirely superseded, but being regard¬ 
ed as the type of a very large and rc- 
fliarkable order, we think it should be 
retained: it cannot, however, be said to 
contain but a few species ; these should 
be grown in a warm greenhouse or cool 
stove, planted in well drained pots of 
light sandy earth, and watered liberally 
in summer, though little or none will be 
required in the dull weather of winter. 
CALAMPELIS (D. Don.) Nat. Or. 
Bignioniacece. C. scabra , syn. Bccremo - 
carpus sealer. The only species is a 
well-known, beautiful, half-hardy, climb¬ 
ing plant, trained to a trellis or to a south 
wall in the open air; it forms a very 
ornamental object through the sum¬ 
mer months, its bright orange coloured 
flowers being conspicuous among the 
pleasing delicate green of the foliage; it 
grows best in rich turfy loam, and should 
be protected in a cold pit through the 
winter; cuttings root readily in a gentle

CALANDRINIA (Humboldt and 
Bonpland.) Nat. Ord. Portulacaceee. 
Very beautiful, dwarf growing plants, 
usually treated as tender annuals, though 
of perennial duration if protected in win¬ 
ter; the seeds may be sown in gentle 
heat about the middle of March, and 
planted in the open air in May, where 
they are a blaze of beauty whenever the 
sun shines upon them; the soil for them 
should be light - and rather dry; the best
