plants are rarely destitute of them from the end of August to the 

 beginning of June. It is a native of Persia, &c. 

 There is a variety with white striped leaves. 

 The seventh is of humbler growth than the sixth, seldom rising 

 more than six or eight inches high, the branches rather herbaceous : 

 the leaves continue green through the year, and the flowers are of as 

 long duration as those of the sixth species. It is a native of the 

 Island of Candia, flowering from April to June. 



In the eighth species the stems are many, thick, green, striated, 

 ascending from a foot to eighteen inches in length, divided into seve- 

 ral branches : the leaves alternate, gradually widening from a nar- 

 row base, ending in a blunt point, thick, smooth, veinless except in 

 the middle, dark green above, somewhat paler underneath : the 

 flowers terminating in corymbs, at first white, afterwards pale pur- 

 ple, without scent. It is a native of Spain, flowering early. in the 

 spring. 



The stems are ridged and woody, and the leaves larger and less 

 bluntly toothed in the cultivated plant. The flowers are also twice 

 as large. 



Culture. The four first annual sorts must be raised annually 

 from seed, by sowing it at different times in the spring, in patches ? 

 in the fronts of borders, clumps, and olher parts of pleasure- 

 grounds, where the plants are to flower, thinning them properly af- 

 terwards. 



The fifth sort may be raised by planting the root off-sets and 

 cuttings as below. 



The three shrubby perennial sorts may be increased by slips and 

 cuttings, which should be planted out in pots, plunging them in a 

 moderate hot-bed, or in a warm shaded border in the later spring 

 and early summer months, water being occasionally given. When 

 well rooted in the autumn, they should be removed into pots, 

 being protected in the winter season in the green-house. 



The first sorts are very ornamental in the open ground, when 

 properly varied. And the latter in green-house, and other potted 

 collections. A few of them may likewise be set out in the warm 

 shrubbery borders.
