Four Valuable Tea Roses, Introduced by the Dingee & Conard Company.
Pearl Rivers.
This fine variety is the result of a union between Devoniensis and Madame de Watteville. It partakes of the leading characteristics of both parents, but resembles the latter most closely; the flowers are large and quite full, with fine peachy red buds; the ground color is ivory white, having the petals delicately shaded and bordered with pale rose; very beautiful; deliciously sweet. 35 cents each; 3 for $1.

Henry M. Stanley. — This rose and Pearl Rivers were introduced with Golden Gate, but none of them has proven of any special value except for summer bedding ; there they have found their place.
