called " Barbadoes-gooseberry." The flowers are very 

 small and simple, spines about half an inch long, leaves 

 fleshy and elliptical. (Soil No. 2.) 



The whole of the plants in the family of Cactese require 

 very little water in winter, and delight in a dry, warm 

 situation. They do not agree with very frequent repot- 

 ting; once a year to young plants, and in two or three to 

 those that are established, with the exception of the large, 

 free flowering species, which should be repotted once in 

 two years, and never be allowed to shrink for want of 

 moisture. 



The operation of grafting is very simple, merely requir- 

 ing an incision to be made, and fitting in it a fresh cutting 

 of another kind, holding the cutting stationary in the inci- 

 sion half a minute, till the juices of the two adhere toge- 

 ther, when it may be said the union is effected, and, in 

 a few weeks, the new branches will grow freely. We 

 have seen the Mammillaria tribe growing neatly upon the 

 triangidaris, and other species of the cereus. 



Carissa, a genus of pretty little plants, particularly C. 

 spindntm, which bears a profusion of white flowers like a 

 jasmine. (Soil No. 4.) 



Ceropegia elegans is the only species of any merit : it 

 is a thin growing, climbing plant, producing a great pro- 

 fusion of very curious flowers of a greenish colour, spotted 

 with brown; the interior and tips of the corolla are set 

 with hairs it is of very easy culture. (Soil No. 7.) 



Caryota. A genus of palms. C. urens is an admired 

 species, produces flowers in long pendulous spikes, which 

 are succeeded by strings of succulent globular berries. In 

 its native state it produces a sweet liquor in large quanti- 

 ties, and no stronger than water. (Soil No. 12.) 



Caryophyllus aromdticus is the clove tree of commerce. 

 The whole plant is aromatic, and closely allied to Myrtus; 

 the flowers are in loose panicles, the leaves oblong, acumi- 

 nate, entire. It is a fine evergreen. Pots must be well 

 drained. (Soil No. 9.) 



Cerberas. About twelve species of strong growing trees, 

 full of poisonous juice. C. thevetia is an elegant plant, with 

 acuminate leaves, and large, nodding, yellow, solitary fra- 

 grant flowers, proceeding from the axil; C. ahouai pro- 

 duces a nut which is deadly poison. C. odallatn, once C.
