Description
SUMMARY OF THE INVENTION

The present invention raltes to a new and distinct variety of rose plant of the grandiflora rose class which has as its seed parent the vareity known as `Sexy Rexy` U.S. Plant Pat. No. 6,713, and as pollen point the variety known as `Pot O' Gold.` The varietal denomination of this new rose is `Macmouhoo.`

Among the novel characteristics possessed by this new variety which distinguish it from its parent and all other varieties of which I am aware are its attractive near white flowers of hybrid tea quality produced in well-spaced clusters on a tall, free breaking plant.

Asexual reproduction by budding of the new vareity as performed in Auckland, New Zealand shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagations.

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying illustration shows typical specimens of the vegetative growth and flowers of the new vareity in different stages of development and depicted in color as nearly true as it is reasonably possible to maek the same in a color illustration of this character.
