convenient to plant it out, give the roots as much room as conveniently can be 
spared ; pot in light sandy loam and heath mould. Great caution is necessary in 
watering ; perhaps more Liparias are killed by being overwatered, than by any other 
means. Never water unless the soil appears dry, and be very sparing in quantity 
during the winter months ; also, unless the weather be excessively dry, under no 
circumstances water overhead — good drainage with potsherds is indispensable, as any 
stagnation is almost immmediate depth. The best way of propagation is to cut olf 
the young tops about an inch and a half long, and plant them in fine sand, cover 
them with a bell-glass, and place the pot in a rather dry heat, wipe the glass every 
morning, and water the pots round the outside of the glass when necessary, in 
preference to pouring water amongst the cuttings, which might speedily damp 
them off. 
MELALEUCA. 
All the species oi Melaleuca deserve cultivation, and are of easy growth ; they 
should be potted in a mixture of two parts sandy heath mould and one part light 
loam. Cuttings of the ripe wood planted in September in pots of sand, covered 
with a bell-glass, and set in a cool airy place till spring, then plunged in a cucumber 
frame or other moist heat, will grow readily. 
METROSIDEROS. 
The culture of these is precisely the same as for Melaleuca. 
MIRBELIA. 
M. DiLATATA. A Small shrub of great value in a collection^ on account of 
the bluish-purple colour of the flowers. It should be potted in a very sandy loam, 
mixed with equal parts of sandy heath mould; it is propagated by cuttings of the 
tender wood, which should be planted in May in sand, and covered with a glass, and 
plunged in a hotbed. 
NIEREMBERGIA. 
All the species should be treated in the same manner as Petunia linearis, for 
which, see Vol. IL, page 219. 
NERIUM. 
N. SPLENDENS and OLEANDER are both very fine plants, and require to be 
potted in very rich soil, say equal parts of heath mould, rich loam, and leaf mould, 
or very rotten dung ; the plants should, if convenient, be placed in a little heat in 
spring to bring them into flower ; they are very readily increased by cuttings of 
half-ripened wood, which should be taken off in April, placed in vials of water 
instead of soil, subjected to a brisk moist heat, or hung up in the stove, and after- 
wards be potted in the above soil. The N. odorum should be kept in a warm part 
of the greenhouse, because it is more liable to be affected by cold than either of the 
other species ; but, in other respects, treated the same as splendens and oleander. 
OXYLOBIUM. 
These plants should be treated in the same way as Gompholohium, Hovea, 
and other New Holland plants of similar habit. 
PIMELEA. 
P. DECUSSATA is the handsomest species of the whole genus ; it should be kept 
in a very airy situation in the greenhouse, potted in sandy heath mould. The plants
