 it forms a fine tree of from 60 to 80 ft. 

 in height. The leaves are larger than | 

 those of the common Box, and when 

 exposed to the sun are of a lighter green, j 

 but it only succeeds well in warm well- j 

 sheltered situations with a dry soil and a ! 

 warm subsoil. Other species are Har- \ 

 land:, microphylla and Wallidiana, few of \ 

 these so precious as the common Box. 

 The variegated forms of Box are seldom 

 so good in effect as the green kinds, at 

 least after they have left the nursery 

 stage. 



climate, and the best places are, as a rule, 

 on well-drained ledges in the rock-garden. 

 Plants of this family should be planted in 

 the rock-garden in open airy situations, 

 free from dripping water, and where the 

 drainage is perfect. Probably hardy 

 alpine species will be found farther south, 

 and we may yet see, in warmer counties, 

 a good collection of bright-flowered Cac- 

 taceous plants on warm rocky borders or 

 banks.

the Cactus Order of plants have proved 

 hardy in England. Opuntia, Echino- 

 cereus, Mammillaria and Echinopsis are 

 among the hardiest. Pretty effects are 

 shown by some Cacti in the open air 

 in Southern England, the plants blooming 

 freely when fully exposed in the sun on a 

 warm rock-garden ; but the want of the 

 sunshine of their native plains is against 

 their being very happy in Britain. 



When the foliage of a plant is perennial, 

 as in Cacti it is well to place it so that it 

 may be safe from injuries, apart from 



proving a picturesque one. It is one of a 

 genus usually tropical, and the interest 

 lies in finding a species which is hardy 

 in the country around London. C.japonica 

 is a loose or free growing shrub with hard 

 prickles, leaves a foot long and very 

 graceful, and handsome yellow flowers in 

 racemes. It grows well with me in very 

 poor soil and seems quite happy as a wall 

 or bank bush. R.
