I lCI'ainiLj (01. 4761) g The present invention relates to 'a new and distinct variety ofrose plant, of the hybrid tea class, having resulted as a definite cross between two well known varieties in an effort to produce a superior yellow rose. The pollen parent was Max Krause and was crossed upon the seed parent Julien Potin. This cross pollination work was carried on by me on my premises in Haps, Holland.

The new variety has been asexually reproduced for several years and its distinguishing qualities appear to be firmly fixed. Tests have been made both in Europe and in the United States of America.

The most outstanding feature of this new variety is the intense and pleasing perfume of its blossoms. Its perfume is very much like that of the 01d Marechal Niel rose which has for. many years been a favorite in mild climates.

. This new variety is a very vigorous grower and is practically disease proof. It is hardy without special protection in the climate of middle Europe where it was originated. This quality enables it to be grown in more rigorous climates than can be done with the Marechal Niel.

. A common failing among yellow rose varieties has been their lack of good form of the opened and four opening buds and flowers of this new variety, together with their stems and foliage.
