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 spoiled in a single week by neglecting to 

 smoke them, particularly if artificial heat is used in spring 

 for forcing.
