1 Claim. (01. 47-431) The present invention relates to a new and distinct variety of rose plant resulting from definite efforts to produce improvements in the quality and color characteristics of a rose in the yellow range, considered by some to be the most attractive coloring for roses.

By making the particular cross, the primary objective is not only attained in respect to the color, but also a number of other desirable characters are produced, enhancing the value of this new variety in comparison with known yellow varieties, among which may be mentioned a vigorous, tall semi-branching habit of bush growth, with long shoots of flowering branches which hold the flowers without drooping; and large sized flowers developing from medium sized pointed buds and made up of thick, sun-resistant petals.

This new variety is further notable in respect to its foliage, which is glossy and well-balanced, and as to its distinctive straight thorns.

Asexual reproduction of this new variety shows the foregoing characteristics come true to form and are established.

Other details of novelty in the combinative characteristics may be noted in the following detailed description of this new variety and the accompanying drawing wherein are illustrated specimens of the flowers at difierent stages of development from bud to (full blown flowers and of the foliage ranging from young to mature stages.
