PHYLLOC ACTUS ACKERMANNI Walp. 

 The King- cactus was taken tro.n 

 Mexico to England prior to 1829 by 

 George Ackermann, and bears the most 

 gorgeous flowers, 6 to 8 inches in di- 

 eter, the acutely pointed, wavy pet- 

 als of a deep brilliant crimson, bor- 

 dered at the base with bright mag- 

 enta, the interior decorated with a mass 

 of white filaments and antlers, the 11 

 stigmata and style also white. The 

 plant blooms freely and may be seen 

 in many San Diego gardens. The plant 

 before me is about a foot hi^'h .and 

 bears one open flower and three buds 

 today (May 3, 1900).

 and require but little water when browsing 

 on it; or in cold coast districts they will do 

 without any water, even in summer, while 

 thriving well on the foliage." The brilliant 

 red flowers are very fragrant, followed by 

 large sweet and delicious fruit, faintly sug- 

 gestive of a strawberry. An ornamen.al 

 plant, easily grown firom cuttings.
