They need a temperature of 70°-90° F. ; neTer less than 

 60°. The rooting medium should be somewhat light, with 

 a quantity of crushed charcoal. Drainage should be very 

 carefully arranged, as they demand an abundance of 

 moisture. Prop, only by seeds, which may remain two or 

 three years in the seed-pan before genninating. For gen- 

 eral cult., see Palms and Areca.

ACANTHUS ((!*a««(OS, thorn). Acanthdcece. Bear's 

 Breech. Mostly hardy herbaceous perennials of vigorous 

 growth and broad foliage, suitable for backgrounds of
