1 Claim. (Cl. 47-60) .The subject of the present invention or discovery is a new and distinct variety of poinsettia plant. (Euphorbia pulcherrima) originating as a"c'ultiva ted sport.

Broadly, this newvariety ofpoinsettia plant is distinguishable from its parent plant, as 'well as from other known varieties, mainly in the shape,- color and arrangement of the bracts which are predominantlya pale greenish tint of creamy. white..color, and. of substantially The, :colors referredj to inj the color tabulation; herein orrespon ub tant al y-wi hth sesh wn Di t ary of Color by Maerz and 'Paul (first edition, 1930.);and are more particularly identified by the color plate of said color standard by recapitulationg in tabular form herein. Z The following is a detailed description of this new variety of poinsettia pl'ant.

Parentage This new variety was originated, cultivated and discovered by me in, a cultivated area of a glass house or greenhouse at my experimental and growing gardens at Encinitas, San Diego County, California. It originated as a cultivated sport of poinsettia plant of the variety commonly known as Ecke White poinsettia plant, which is not patented but has been known in the trade by that name for many years, and is alsoreferred to by that nomenclature in pertinent literature such as United States Plant Patent No. 1,085, dated April 22, 19 52, and bulletins of the agricultural experiment stations of several States, such as in Greenhouse Potted Plants, Ohio Agricultural Experiment Stati0n, Wooster, Ohio (September 1955).

Bracts with a relatively small opening at its center due to'the short petioles,

The large bracts, in planar contour, are elongated and prolately ovate-.accuminate; they are numerically greater in number of individual bracts than any of the known varieties of white poinsettias which have broad prolately This new'variety of oinsettia" plant has been asexually reproduced and cultivated by me in my said greenhouse or glass house by cuttings, and successive reproductions thereof have remained true to type and the herein describedcharacteristics through the propagation, cultivation and asexual reproduction of several generations of this new variety, and it 'has shown its qualities and characteristics to be permanently fixed. producing this new variety I have found it satisfactory and efficient to cut pieces of stalk of soft Wood substan- In asexually revidual pots. My experience has been thatfthe optimum.

ovate-acuminate bracts, the involucre having a predominating majority of the individual larger bracts of greater ties of white poinsettias, thus providing a wide diameter to the involucre ranging up to six to eight inches. 7

At the optimum of their maturity the bracts maybe generally and broadly described as predominantly a pale greenish tint of creamy white with some, but .not all, of the bracts having a pale greenish-yellow tint of creamy white in the outer terminalend portion of their. planar area, and a'pale green tint to the peripheral edge portionof the bracts, as said coloration is more particularly describedin the color tabulation below. The venation of the bracts is of the herringbone type. The petioles of Inflorescence A node is formed at the upper axial end of each main stalk'or peduncle from which the bract-bearing branches or spurs grow upwardly and expansively apart, being usually three in number, and upon these branches or spurs grow a plurality of flower cyathia on short sub-acaulescent stems. Each cyathium is cup-like and contains a single pistillate flower surrounded by numerous staminate flowers, the pistillate flower pushing upward to the top where the stigma is spread for polination. The cyathia are a pale green color at their base, blending into a pale yellow at the opening of the cup. Alongside of the cyathia are the nectary or nectar cups the open labiate mouth of which is of a more vivid orange tint of yellow than the opening of the cyathiar General character of growth This new variety of poinsettia plant is further characterized by its strong and luxuriant growth, rendering cultivation and propagation relatively easy under favorable conditions which are stan dard and normally exercised by those skilled in cultivation of oinsettia plants.

Having described and illustrated my new variety of poinsettia plant, I claim: t 7 1 Y a A new anddistinct variety of poinsettia plant, substantially as illustrated and described, characterized by a central inflorescence and an involucre of a large "number of prolately-ovate-acuminate bracts of predominantly'a pale greenish tint ofcreamy white color and of substantially greater width than known varieties, the'bracts radiating on relatively sho'rt'petioles from the inflorescence and the side edges of individual bracts overlapping the side edges of the next adjacent bracts in wreath-like relation. r
