No. 54 (P. Brauer).—This variety was named by the raiser Princess of Naples; but inasmuch as our Italian representative, C. Sprenger, had, prior to the introduction of this variety, named his great new Rose, offered elsewhere in this book, dy special permission, in honor of the Princess of Naples, this variety has no claim upon the name; we therefore offer it by number only, which fact does not lessen its value. Mr. Brauer’s Rose is the result of a cross between Duc de Magenta and Safrano, and is a free-blooming variety of great excel-lence. In growth and foliage it resembles Maman Coche?. Buds long and open slowly. Outside of petals yellowish rose, inside somewhat lighter rose cream, edges recurving as in La France; very sweet; splendid variety; strong and free bloomer. Extra full.
You could include the Jardins de France 1897 p.474 reference: "L'horticulteur Paolo Brauer, de San Remo, expose deux nouvelles Roses the. L'une d'elles, surtout,Principessa di Napoli....La Furstin von Hohenzollern a un coloris etrange, rose lilace sur fond jaune..." My keyboard won't do accents, so you will have to retrieve the whole paragraph (online).
The quote is added. These snippets are a bit tricky. "Jardins de France" is the modern name of the publication which was called "Journal de la Société nationale d'horticulture de France". The same search also shows this publication and page 474 but without a snippet! The year is also questionable. The volumes were usually like 1897-1898. Page 474 seems to indicate Spring 1898 to me, which is in line with all the other publications on this subject.
Here you can find the 1898 issue of Journal de la Société nationale d'horticulture de France but I could not find any trace of Principessa di Napoli .... you may be better than me! http://bibliotheque-numerique.hortalia.org/items/show/386 .. the 1897 issue looks more likely!
It may have first appeared in the Ketten catalogue in 1898 but 1897 would be a better date to give since it was much praised in several articles in Die Gartenwelt of 1897 and one of these refers to the editors having received the rose for consideration in the previous January!
