petaled, and sonrfe of them large ; centre full of sta- 

 mens ; the foundation of the natural order Cistinea. 



Clematis, Virgin's Bower. There are only six, of 

 these belonging to this, all climbing plants. C. aristdta 

 and C. brachiata are the best; flowers in racemose 

 clusters, pure white ; foliage small ; and natives of the 

 Cape of Good Hope. The foliage of C. aristdta is 

 cordate and blotched. 



Cobcea scdndens, the only species. It is a climber of 

 very rapid growth, has been known to grow above 

 two hundred feet in one summer; large bell-shaped 

 flowers; when they are newly expanded, they are of a 

 pale green colour, and change to dark purple; will 

 grow in the garden during summer, bearing a con- 

 tinual profusion of flowers, but will not stand frost. 

 When this plant becomes too large in the house, do 

 not cut it close to the root, except there is a young 

 shoot arising to carry off the superabundant sap, for 

 the old wood will not push, which will soon cause a 

 mortification. 



The best method to adopt in such case is to turn 

 back a shoot, and lay it in the ground to root, when it 

 will become a young plant; which should always be 

 done as soon as it appears unsightly. It does best to 

 be planted in the ground, but will not give any satisfac- 

 tion as to flowering in a pot. It will flower as an an- 

 nual if sown in pots this month, and placed in a warm 

 room or hot-bed, and planted into the garden about 

 the end of May. 



Coronillas, a very few are fine species in the Green- 

 house. C. glauca is a celebrated plant amongst us, as
