potsherds, to ensure the permeability of 
the mass both to air and ■water. Yoimg 
plants make astonishing progress when 
shifted from small pots to large ones, 
but it is not safe to continue the method 
when they have attained a considerable 
size; a cold pit, with a slight shade over 
to protect them from the sun, will be 
found best for them in summer, and an 
airy position in the greenhouse near to 
the glass shouldbe seemed in winter, light 
and air being essential to preserve them 
from damp and mildew. Water may be 
given plentifully in warm weather, but 
the quantity in the dull months must be 
very limited ; in summer, if the plants 
are placed out of doors, or in a position 
exposed to the sun, some contrivance 
must be resorted to in order to screen the 
pots, that the roots which are very delicate 
may not receive injury, while in winter 
it is better to have them open to assist 
in occasionally drying the soil. In short, 
their treatment may be assimilated as 
nearly as possible to that of the Heath, 
for they are found to thrive best when 
grown together, and under the same 
management. L. formosa scarlet, and 
L. biloba nana , blue, should be in every 
collection. 
LEIANTHUS (Hooker.) Nat. Or. 
GentianacecB. Handsome stove biennials, 
requiring to be grown in peat, loam, and 
leaf-mould; the seed should be sown as 
soon as it is ripe in the autumn, and 
the young plants kept singlyin small pots 
through the winter until the January 
following; they may be placed in large 
pots where they are to flower, then by 
plunging in a moderate bottom heat, and 
preserving a moist atmosphere about 
them, they will be induced to grow freely, 
and as a natural consequence bloom 
copiously. L. nigricans has singular dark 
purple, almost black, flowers, which are 
produced by hundreds. L. longifolius 
and glauca have yellow blossoms. 
LEONOTIS (Persoox.) Nat. Ord. 
Labiatce. L. Leonurus is a magnificent 
greenhouse plant from the Cape of Good 
Hope, producing brilliant scarlet flowers; 
rough sandy peat and loam, with plenty 
of air and a supply of water proportionate 
to the season, will not fail to cause it to 
grow well and flower finely. The other 
species are comparatively not worth 
the trouble of growing where this is 
present. L. nepetaefolia and ovata, are 
tender annuals, and L. intermedia is a 
stove plant. 
LEPTOS1PHON (Bextham.) Nat. 
Ord. Folemoniacere. These Californian 
annuals are among the most beautiful we 
possess, they are dwarf and neat in ap¬ 
pearance, profuse bloomers, aud perfectly 
hardy; we have now a mass of L. densi- 
florum before us, and certainly nothing 
can be more perfect as a bedding plant, 
for it is an entire sheet of pretty white and 
lilac flowers, not more than eight inches 
from the surface of the soil; there are 
two species, that first mentioned, of 
which, as hinted, there are two Varieties, 
and another not quite equal, called an- 
drosaceus ; they grow freely in any good 
garden soil, and by successive sowings 
may be had in flower at any part of the 
summer or autumn, they are also well 
adapted for growing in pots to bloom in 
winter. 
LEPTOSPERMUM (Eorster.) N. 
Ord. Mgrtacere. Handsome greenhouse 
plants from New Holland and adjacent 
parts, with white flowers, and myrtle¬ 
like character, and requiring much the 
same treatment. 
LEPTOTES (Bindley.) Nat. Ord. 
Orchidacere. The two species known 
of this plant are each pretty little epi¬ 
phytes, producing small rush-like leaves 
and lovely white flowers, having a blotch 
of bright crimson on the lip. They 
grow best when attached to a block of 
wood suspended from the roof of the 
stove at the coolest end; they may also 
be grown in a pot or basket filled with 
rotten wood, fibrous peat, and a little 
moss, but in this case must be well 
drained, properly elevated above the sur¬ 
face of the soil, and carefully watered. 
LEUCO-CORYNE (Lixdley.) Nat. 
Order, Liliacece. Half-hardy, bulbous- 
rooted plants, pretty, and deserviug at¬ 
tention; they grow best in peat and 
loam, and may be cultivated either in 
pots or in the open ground, if they are 
taken up and preserved in sand through 
the winter. Their flowers are large for
