raised from cuttings. Sorts : C. Bolusii, C. ciliata, C. coccinea 

 (Fig. 543), C. cordafa, C. fakata, C. margina/is, C. jasminea^ 

 C. ?'osularis, and C. versicolor. C. coccifiea is a very handsome 

 plant, which is extensively cultivated. 

 Young plants are best grown singly 

 in 4in. or 6in. pots, and benefit by 

 manure during summer. 



Euphorbias. — Many of these very 

 much resemble Cacti, but apart 

 from their peculiar appearance are 

 not worth growing, except E. spleii- 

 dens and E. pulcherrima {Poitisettia 

 -bidcherrima). Sorts: E. triangularis, 

 E. grandicomis, E. Bojerii, E. splen- 

 dens, and E. erosa. E. splendens is a 

 climber, with brilliant scarlet flowers, 

 and will blossom nearly all the year. 

 It may be grown either on the roof 

 or on balloons in pots. 



Furcr^as are handsome plants 

 allied to the Agaves, and require 

 the same treatment. Sorts: E.cubensis^ 

 E. elegans, 

 and E. undulata.

they are allied). 

 Some of them have beautifully 

 coloured leaves, smooth and shiny, 

 but sometimes rough. They also pro- 

 duce spikes of long white pendulous 

 flowers, occasionally rough. Sorts : 

 G. angtistifolia, G. drevifolia, G. glabra, 

 G. spiralis, G. pulchra, G. fiigricans, 

 G. sulcata, and G. trig07ia. 



Haworthias are curious plants, also allied to the Aloes ; they 

 have grey flowers. Sorts : H. atrovirens, H. attenuata, H. fasciata, 

 and H. viscosa. 



Mesembryanthemums (Fig-Marigolds). — Many of these have 

 very fine and highly-coloured flowers. The genus is very large, 

 and all the species have thick, fleshy leaves, which in some cases 

 are very pretty, and in others very curious. They may all be 

 propagated by seeds, and most of them by cuttings. Many are 

 very useful for basket-work, having a creeping habit. Creeping 

 sorts are : M. attenuatiim, M. australe, M. calyci?ium, M. densuin 

 (Fig. 544), M. florihundum, Al. glaiLCesceiis, and M. striatum. 

 Annuals : M. calendulaceum, M. californicum, M. crystallinuin
