The New Varieties for 1865.
Hybrid Perpetuals to be sent out Nov. 1, 1864:
3. Reubens [sic] (C. Verdier).— Shrubby, flower medium, half full, red velvety garnet, glowing. The issuer of the list here translated states it to be the most brilliant colour he knows. I should say have nothing to do with flowers described as "nearly full," or "medium size," which usually mean in England loose and little.
