are bright purple, and last 

 a long time. C. Leeaniis 

 is cone-shaped, and 

 about gin. in height ; 

 the flowers are red, 

 and produced several 

 together on the top. 

 C. multiplex (Fig. 

 527) is Pear-shaped, 

 with very deep cut 

 ridges and clusters 

 of spines. Others 

 are C. paucispinus^ 

 C. pleiogoniLS^ C. 

 polyacanthus^ and 

 C aggregatus. 



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 



serpentijius 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 

 scented. C. Berlaiidieri (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. Alany are really 

 handsome, whilst others are 

 rather curious. The flowers 

 are large and brightly- 

 coloured — various shades of 

 yellow, white, rose, and pur-
