among a hundred is but little over an 

 inch in height and diameter, and in 

 earlier days they were literally worth 

 their weight in gold. The flowers are 

 open only in sunlight. 

 Variety PECTINATA KS. 



Genus PHYLLOCACTUS Unk. 



Epiphytal plants with spineless flatten- 

 ed leaf-like branches, with a prominent 

 midrib, mostly with large showy flowers, 

 from creamy white to the richest crim- 

 son and scarlet, produced from notches 

 In the margins of the stems. 



Readily produced by cuttings or seeds, 

 the phyllocacti are established favorites, 

 and hundreds of varieties have been pro- 

 duced by hybridization. Young growth 

 often cylindrical, then triangular, finally 

 assuming the flattened form. 



PHYLLOCACTUS ACKERMANNI Walp. 

 The King cactus was taken from 

 Mexico to England prior to 1829 by 

 George Ackermann, and bears the most 

 gorgeous flowers, 6 to 8 inches in di- 

 ameter, 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 fllaments 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 hish and 

 bears one open flower and three buds 

 today (May 3, 1900).

 portion, of a bright, but lighter, crim- 

 son. Filaments white, antlers canary 

 yellow. This is a general favorite in 

 San Diego gardens .also, producing its 

 lovely flowers in the greatest profusion.

 among the Phyllocacti, the stout flat- 

 tened stems 4 to 5 inches broad, deeply 

 crenated and commonly 8 to 10 feet 

 high. The flowers are 7 to 8 inches lon.g, 

 about 6 inches in diameter, the petals 

 of a delicate, clear, creamy white, the 



sepals and tube of a reddish hue. Na-
