are bright purple, and last 



a long time. C. Leeanus 



is cone-shaped, and 



about 9in. in height ; 



the flowers are red, 



and produced several r " 



together on the top. 



C. multiplex (Fig. 



527) is Pear-shaped, -- 



with very deep cut x 



ridges and clusters -. 



of spines. Others 



are C. paucispinus, 



C. pleiogonus, C. 



polyacanthus, and 



C. aggregates. 

 Besides the 



above there are a 



few whose charac- 

 teristics are rather 



nondescript, and so 



are given here by 



themselves. C. fla- 



gelliformis has pros- 

 trate stems, which are sometimes grafted like Epiphyllums ; it 



is very useful for basket-work ; the flowers are bright red. C. 



serpentinus at first has erect 

 stems, but as they grow they 

 fall and trail on the ground 

 unless supported; the flowers 

 are large, purple, and sweet 

 1 scented. C. Berlandieri (Fig. 

 528), with procumbent stems 

 and purple flowers, C. lepta- 

 canthus, and C. procumbens 

 are also worth growing. 



Echinocactus (Hedge- 

 hog Cactus). — These, like 

 the Melocactuses, are globu- 

 lar, very few producing 

 offsets, and also attain a 

 large size. Many are really 

 handsome, whilst others are 

 rather curious. The flowers 

 are large and brightly- 

 coloured — various shades of 

 yellow, white, rose, and pur-
