These are splendid plants, approaching in beauty 
to some of the finer Cattleyas. The sepals and 
petals of L. anceps, and its variety, are pale lilac; 
the central lobe of the labellum is a beautiful deep 
purple, and the mouth of the tubular part yellow 
and white. L. grandiflora has never flowered in 
this country, and is found rather difficult to grow. 
The others are of very easy cultivation, requiring 
precisely the same treatment as their rivals, the 
Cattleyas,

Lythraceas. A most splendid genus of plants, espe- 
cially L. reginae, the flowers or which are produced 
in panicles ; they are at first pale rose-coloured, 
and gradually deepen to a beautiful purple. The 
soil best adapted to these plants is a mixture of 
peat and loam. All the species, except L. indica 
and its variety, are rather difficult to cultivate ; 
they require a strong heat, and very little water 
in winter. In summer, they grow freely, and 
require plenty of room to grow, with a good supply 
of water; cuttings root readily in sand, under a 
glass, in heat.

Lagoecia, Linn. From lagos, a hare, and oikos, a 
house ; the seeds enveloped in the hairy involu- 
crum have been compared to young leverets. Linn. 
5, Or. 2, Nat. Or. Vmbelliferoe. The seeds of this 
plant should be sown soon after they are ripe, in 
autumn, because if deferred till spring, they com- 
monly remain a year, and sometimes longer, before 
they grow

Lagonychium, Bieberstein. From lagos, a hare, and

the plant. Linn. 10, Or. 1, Nat. Or. Leguminosce. 
This plant will succeed in a warrn situation in the 
open border, if protected by a mat in severe weather 
in winter. It may be increased either by seeds, 
layers, or cuttings, taken off at a joint when very 
young, and planted in sand, under a glass. Syno-

Lahaya, Roemer and Schultes. In honour of M. 
Lahaye, a diligent botanical gardener. Linn. 6, 
Or. 1, Nat. Or. Hlecebracece. This is a genus of 
rather pretty plants. The shrubby and herbaceous 
kinds grow well in sandy peat, and may be increased 
by cuttings planted in sand. The annuals require 
similar treatment to other hardy and tender annuals.

plant on account of its gay and lively -looking j 
colours. Linn. 15, Or. 6, Nat. Or. Leguminosce. 
This is one of the prettiest of the New Holland 
leguminous plants. It requires an airy part of the 
greenhouse, and to be similarly treated to the 
genus Hovea.

Lambertia. Named by Smith, in honour of Aylmer 
Bourke Lambert, Esq., F.R.S., V.P. L.S., one of 
the most liberal botanists in Europe, and the pos- 
sessor of a splendid herbarium, open to every man 
of science. Linn. 4, Or. 1, Nat. Or. Proteacece. 
Very handsome plants, succeeding well in loam 
and peat, with the pots carefully drained. Water 
must, at all seasons, be very cautiously suppUed ; 
for if once the soil in the pots gets saturated, the 
plants will soon become sickly, and perish. Cut- 
tings taken off at a joint, before they begin to push, 
will root in sand, under a glass, if secured from 
damp.
