224 CROWEA LATIFOLIA, &c. 
The soil most suitable is a mixture of equal parts sandy loam, heath-mould, and 
sand ; it is not well to break it very fine, but it must be well mixed, and if a few 
broken potsherds be mixed through, it will prevent the possibility of the soil, when 
in the pots, becoming close and sodden, which is very disadvantageous to most plants. 
Select pots rather roomy, as the very habit of the plant's growth shows that its 
roots ought not to be cramped. If it could be turned out into a shady border in the 
stove, this would be far preferable. In potting, give plenty of drainage ; for although, 
in its native woods, the situations it naturally occupies are damp, yet its preference 
for a granitic soil indicates that stagnant water would soon injure its roots. On 
watering during the season of growth, little need be said : syringing may be repeated 
every day, and a liberal supply at the roots ; but when the plant is at rest, this must 
be so far diminished as to merely amount to what will keep it from drooping. 
During summer, shade is as indispensable for this plant as for Orchids, but in 
winter this must be quite removed. 
Propagation is effected by cuttings, taken off when the wood is something more 
than half ripe, and planted thinly in a pot of fine sand, and placed under a hand- 
glass in heat. When the plants are struck and potted off, still allow them to remain 
in the propagating-house, until they have recovered from their removal. 
Galipea. — Sixteen species of this highly fragrant and beautiful genus are known 
and described, all natives of Tropical America ; but only two are yet known in British 
collections, although it is not unlikely several others are already in this country. 
The prevailing colours of the flowers are yellowish-white, tinged on the under side 
with pink, and with the calyxes more or less coloured ; — trifoliata is the best known, 
being introduced in 1816, and odoratissimum in 1829 : this latter species, although 
yet scarce, is already in a few choice collections ; it is an exceedingly fragrant plant, found 
in the woods of "Kio Janeiro, by the late Sir Henry Chamberlayne. When in 
flower, the whole atmosphere of the hothouse is perfumed as if with jasmines, and the 
period of blossoming lasts some time." * Its stem grows upright and is branchless, 
something like that of Erythrochiton, and it attains the height of four feet. Several 
other species emit a most delicious fragrance, and are in other respects highly 
interesting. Cusparia is the species which produces the medicinal drug called 
Angostura bark. 
The culture of this genus resembles in several particulars that of Erythrochiton. 
Soil, potting, drainage, temperature, watering, and shade are the same ; but all the 
species of this genus, to flourish well, require the application of a good bottom-heat, 
either by means of a tank or by the pot being plunged in a bed of fermenting 
materials, as tan or leaves. 
Lemonia. — For the culture of this genus see t. 73 of this volume of Mag. Bot.
