south sides of the mountains. It is on the northern side that 
S. cruentus is found, inhabiting groves of Laurels, Myrica 
Faya, Arbutus, Heaths, Ilex, and other shrubs, among which 
the Sweet Chesnut, and downy-leaved Oak are naturalized, 
and associating with species of Convolvulus, Ranunculus, 
Rubus, Geraniums, Strawberries, Violets, and similar plants. 
In these regions the air is moist, the sky is almost always 
overcast with clouds, especially during the day, while in 
the summer time fogs and mists are common, and in winter 
storms and heavy rains; there is no frost, and when snow 
falls upon the upper limits of the zone it melts immediately. 
The surface of the country is broken up into valleys and 
mountains, and the soil, although volcanic, is well covered 
with mould. How different this is from ordinary notions 
of the climate of the Canaries I need not say ; it is obvious 
that if plants from such situations are treated as if they were 
the natives of an arid and sun-baked land, no success could 
possibly be obtained. In fact its treatment is that of a green- 
house plant, loving moderate temperature, and more moisture 
than usual when growing. 
It is a half-hardy greenhouse perennial, of easy culture, 
growing well in any rich garden soil, and well adapted for 
early forcing, flowering nearly all the year. It is increased 
either by cuttings made of the young shoots in summer, or 
by division of the old plants early in the autumn. The 
cuttings, when rooted on the divisions of the old plants, 
should be transferred to small pots, and kept shut up close in 
a cold frame or pit for a week or ten days, shading them if 
the sun is very strong, and shifting them afterwards, as they 
require it, into larger pots; no artificial heat is necessary, 
except to keep out frost during winter. The principal 
thing to be attended to is the keeping the plants free from 
the green fly, which may be done by gentle fumigation, for 
if the fly is once allowed to remain until the leaves begin to 
curl, it will be impossible to remedy the evil, and the very 
best plants may be p in a single week by neglecting to 
smoke them, particularly if artificial heat is used in spring 
for forcing.
