Marechal Niel Rose (G. B.).
"The specimen sent I believe to be the true Marechal Niel. There is no other Rose, except Isabella Gray, that could possibly represent Marechal Niel. The bloom and truss sent appear to be the same as produced by Marechal Niel sent to me by M.E. Verdier and Mr. Keynes. If 'G. S.' would send a truss early next season I could better determine the case. I have bloomed contemporaneously and beautifully Marechal Niel and Isabella Gray. The points of difference seemed to me to be—Marechal Niel is larger, thicker in petal, easier to unfold, larger in foliage, and apt, late in the season, to rot at the neck of the stalk. Isabella Gray is a little smaller, fuller, more golden, narrower in the leaf, longer in opening, and hardier late in the season at the neck. An amateur, seeing them side by side here, told me that he could see no difference. A critical eye would see that the above distinctions were the difference. They were both lovely Roses, and I have bought twenty-five more of Marechal Niel on its own roots, and three more of Isabella Gray. Both were bloomed here in the open garden.—W. P. Radclyffe."

It is an interesting fact that Isabella Gray, the golden-yellow rose, which became famous in the first year of the National Rose Show, and has scarcely been heard of since, has gain challenged criticism in a bold manner by her appearance in first-class winning collections at all the great exhibitions this season. That Isabella Gray passed out of public view for atime was simply due to the fact that though she produced plenty of flowers, those flowers usually refused to open.
