best varieties are giganteus, Maximilian^ and orgyalis. 

 Rigidus and its varieties better known as Harpalium 

 rigidum (Prairie Sunflower) is a native of Texas, and 

 some of its varieties are amongst our most effective and

 sulphur-coloured variety is very beautiful.

 best known are Dumortieri, flava^ andfutva.
