Globe Thistles are coarse-growing plants of the easi- 

 est culture, and are suitable for naturalizing in wild 

 gardens and shrubberies. An English gardener with 

 an eye for the pirturfsqun (\V. Goldrinir) recommends

ECniS6V8IS (Greek, hedgeJiog-Uke). Caetdeeo' kE\ 

 UKCHiN Cactus. Stems spherical to ellipsoidal or rartl\ 

 columnar : ribs prominent and usually sharp angled 

 fls. usually long trumpet-shaped, ovary and tube covered 

 with linear-lanceolate, cuspidate bracts which become 

 longer toward the outer end of the tube, where thej pass 

 gradually into the outer petals, in their axils bearing 

 long, silky, wavy hairs and usually a few rather rigid 

 bristles. This is a well marked genus, though by som. 

 authors combined with Cereus, confined entirely to 

 South America. Culture as for Cereus.
