' flowers and foliage of my new variety bear a close 1 Claim.
My invention relates to anew variety of African violet plant, the novel characteristic of which resides particularly in its'production of uniformly white flowers.
This new variety was originally produced by cross-pollinization of the well known blue variety of Saintpaulia ionantha, also known as the African violet and the Usambara violet, with a light pink spontaneously occurring sport of the same species. I first selected a specimen of this pink sport, and, as this specimen was nearing full maturity, pollen therefrom was placed on the stigma of a fiower of the conventional blue variety From the seed produced by the latter, plants were grown, some of which produced the conventional blue flowers, some of which produced the previously known pink sport, and a few of which plants uniformly produced the white flowers characteristic of the variety which I regard as my invention.
This new variety uniformly producing white flowers, was reproduced asexually by rooting leaf cuttings in sand or a similar rooting medium, in
the manner in which African violet plants are customarily propagated, and it has been demonstrated that all of the new variety so propagated uniformly produce the characteristic white flowers.
In structure, as distinguished from color, the
slight touchof green being visible interiorly of the corolla tube. The twinstamen heads are of approximately the Primuline Yellow color as shown on Plate XVI of Ridgways "Color Standards and Nomenclature, 1912 edition. The upper surfaces of the leaves carry a large number of short silvery hairs and are of approximately the Elm Green color as shown on Plate XVII of the above identified publication, although 20 lighter shades are visible in certain areas. The
under sides of the leaves are heavily veined and are of approximately the Pale Fluorite Green color as shown on Plate XXXII of the above identified publication.
I claim:
A variety of African violet plant substantially as shown and described, characterized particularly by its white flower.
