Germanica (Muller, Gravereaux, 1890). This variety has single Rose coloured flowers. It is of moderate growth, making a bush 3 feet or 4 feet in height. The chief interest of this plant, for the possession of which I am indebted to the kindness of M. Jules Gravereaux, lies in its having been the parent of Conrad F. Meyer and some other members of the group. Dr. Muller seems to have brought out another Rose of the same name in the year 1900, which I have not seen.

Conrad Ferdinand Meyer... Herr Dr. Müller, welcher uns ja schon mehrere wertvolle Rosen gezüchtet hat, besass diesen Sämling schon seit 1893. Ueber die Abstammung schreibt uns der Züchter Folgendes. "Mütterlicherseits stammt diese Rose von einem Sämling (Gloire de Dijon x Duc de Rohan) aus dem ersten Jahre meiner Versuche; väterlicherseits von Rugosa Germanica (einem Zufalls-Sämling von Kaiserin des Nordens aus dem Jahre 1887). Alles andere ist Ihnen ja bekannt."

Translation:
Conrad Ferdinand Müller...Dr. Müller, who had obtained several valuable roses for us, had this seedling since 1893. The breeder wrote us the following about the parentage: "The seed parent of this rose is a seedling (Gloire de Dijon x Duc de Rohan) from the first year of my experiments, pollen parent is Rugosa Germanica (a chance seedling of Kaiserin des Nordens from 1887. All other is already known to you".
