Rose rash

Rose Rose, n. [AS. rose, L. rosa, probably akin to Gr. ?, Armor. vard, OPer. vareda; and perhaps to E. wort: cf. F. rose, from the Latin. Cf. {Copperas}, {Rhododendron}.] 1. A flower and shrub of any species of the genus {Rosa}, of which there are many species, mostly found in the morthern hemispere [1913 Webster]

By cultivation and hybridizing the number of petals is greatly increased and the natural perfume enhanced. In this way many distinct classes of roses have been formed, as the Banksia, Baurbon, Boursalt, China, Noisette, hybrid perpetual, etc., with multitudes of varieties in nearly every class.
