 (R. liiiea var. persiana, Lem. R. lutea var. plena, 

 Hort.), PERSIAN YELLOW, is a double-fld. form; it is 

 more double and more free-flowering than the Sulphur 

 Rose. F.S. 4:374. Var. Harisonii, Efort., HARISON'S 

 YELLOW ROSE, is of paler color and a little less double 

 than Persian Yellow, but it blooms more freely, is more 

 vigorous, hardier and easier to grow. It is of American 

 origin and may be a hybrid of the Austrian Briar rose 

 with R. spinosissima. F.E. 18:6.

 R. sulphurea, Ait. R. Rapinii, Boiss. & Bal.). SULPHUR
