ON THE TREATMENT OF A FEW GREENHOUSE PLANTS.

Water them freely, and take care not to let the water at any time stand at the roots. 
K. monophylla does exceedingly well planted in a bordei' in the greenhouse or 
conservatory ; in this situation it will grow strong, and will therefore require more 
water than when growing in a pot. Cuttings of the whole, planted in a pot of sand, 
in a little heat, under a bell-glass, will root freely. 
BuTtonia conferta, is a pretty little plant with heath-like foliage, but to 
manage it well is a matter of much difficulty. The most frequent error committed 
in the management of it is over watering, this cannot be too cautiously guarded 
against, as it is extremely tenacious of moisture. In potting, use a little peat and 
sand, with a trifling portion of loam incorporated through the whole, but be careful 
to drain well with reduced potsherds. Let it, at all times, enjoy an unencumbered 
situation in the greenhouse, where light and air can reach it without interruption. 
Cuttings taken when the wood is tolerably fine, and put in sand under a bell-glass, 
will, with care, produce roots. 
Boronia Pinnata. An elegant little greenhouse plant, producing its pink 
flowers early in the spring, which diffuse a scent like that of the hawthorn. This 
species has many admirers, but there are few that can grow it well. It should in 
summer be much attended to, as regards the application of water, which must always 
be given in moderate quantities, otherwise the plant will sustain injury. Pot it 
in sandy peat, observing to drain well, and be mindful not to let the pot room be 
over much. It dehghts in plenty of light and air, and will therefore do better if 
not much crowded with other plants. Cuttings require particular attention, for they 
are very liable to damp while in the striking pot ; they should be potted in sand, 
with a glass put over them, and afterwards set in a cool frame ; the lights of which 
should be occasionally taken ofl* to allow the cuttings to dry, otherwise they are 
very likely to go off from excessive moisture. 
Helichrysum. This genus is amongst the best of our greenhouse plants, and 
is tolerably easy of culture. The species are much esteemed for the brilliancy of 
their flowers, not only when growing, but also when preserved in a dried state. 
The annual species should be raised on a hotbed, and afterwards, if they be trans- 
planted or potted, let them be removed to a warm situation. They are all natives 
of the Cape of Good Hope, and will do well potted in sandy peat. Care in watering 
is particularly required in all, but perhaps more so in H. proliferum and fulgidum ; 
these we have more than once observed to suff"er from a super-abundance of this 
element. They are not easily propagated ; still, cuttings put in sand and placed in 
a moderate heat, not covered with a glass, carefully watered, may, with attention, be 
brought to produce roots. 
Epacris, Eucalyptus, Pimelea. Most of the species contained in these 
three genera are very valuable plants ; and we may add, that the greater part of 
them are natives of New Flolland, and therefore form a part of our greenhouse 
collections. They thrive best in a peaty soil, although some of the stronger growing 
species of the Eucalyptus, for instance the E. pauciflora and perfoliata, require 
a loamy soil. Water may be given freely to all of them while growing. Cuttings 
will strike readily potted in sand, placed under a bell-glass.
