BOMAREA 



A genus of twining Alstroemerias, the stems in some of 

 the species growing to a length of 20 feet or more. They 

 resemble lilies in not developing lateral shoots, so that if a 

 growing stem is topped it is incapable of further growth. 

 The leaves are peculiar in being twisted on their petiole, 

 so that they are really upside down. The flowers are 

 produced in terminal umbels, and in some species these 

 umbels are several feet across. They are exactly like the 

 flowers of Alstrcemerias in form, and in colour they are 

 invariably bright and attractive. They all grow best in a 

 sunny, airy greenhouse, preferring a peaty soil and plenty 

 of water in summer. Their stems will twine round a pillar 

 with pretty effect, and when they are in flower they are most 

 decorative. The species in cultivation are B. Caldasiana, 

 B. Carderij B. multiflora> B. oligantha^ B. patacocensis (con- 

 ferta) (see Plate XVII), and B. Salsilla (oculata). Propagated 

 by division or from seeds. 



BOUGAINVILLEA (see Plate XVIII) 



The Bougainvilleas are scandent shrubs which, like 

 some Roses, are dependent on their straggling habit of 

 growth and stout spines for success in climbing. Like 

 Roses, too, they may be grown, with a little management, 

 to be self-supporting bushes. They are very popular 

 garden plants in tropical countries, where they often form 

 stout, woody stems and cover a large amount of space 

 with their interlacing branches. They endure severe
