MILKWEED PLANT Filed May 18, 1971 FIG. 3

lAll/EA/ TOR BAP/VH1 L. COB/A A TTOR/VE) United States Patent Ofice Plant at. 3,316 Patented Feb. 27, 1973 U.S. Cl. Flt-88 1 Claim ABSTRACT OF THE DISCLOSURE A new and distinct plant variety of the milkweed family is structurally closely similar in appearance to plant specimens of the Hoya carnosa compacta variety but is distinguished from the latter variety by characteristic leaf blade border variegations.

The invention relates to a new and distinct plant variety of the milkweed (Asclepiadaceae) family and which has been named the Hoya carnosa compacra (cv) Marginalis by the inventor.

Certain plants of the milkweed family are well known in the foliage plant market and among these are those of the Hoya carnosa compacta variety. A lesser known related variety found in the marketplace but which is rapidly gaining popularity is the Hoym carnosa compacta (cv) Mauna Loa variety and which forms the subject matter of the inventors co-pending application, Ser. No. 808,025, filed Mar, 13, 1969.

Plants of the Hoya carnosa compacta variety have a compact growth habit with leaf blades which generally fold along the midrib of the blade and which have a solid green field which encompasses the entire upper epidermal area of the blade. Plants of the Hoya carnosa compacza (cv) Mauna Lao variety are structurally closely similar in appearance to plant specimens of the Hoya carnosa compacta variety but are readily distinguishable from the latter variety by characteristics which, among others, provide variegated leaf blades that have an albino center field which is surrounded by a green border area.

A substantial segment of the purchasing public has a preference for plants which exhibit variegated leaf blade characteristics and a general object of the invention has been to develop a plant variety which is related to both the Hoya carnosa compacta variety and the Hoya ca rnosa compacta (cv) Mauna Loa variety but which is readily distinguished by the purchasing public from such varieties by variegated leaf blade characteristics. The object of the invention has been fully realized as will be evident from the following detailed disclosure.

Plants of the new variety generally resemble plants of the Hoya camosa compacta variety in structural appearance but are distinguished from this variety by variegated leaf blades which have albino border areas in the upper and lower epidermal areas of the 'leaf blades and which generally surround solid green center fields. The new variety is distinguishable from specimens of the Hoya carnosa compacta (cv) Mauna Loa variety for reasons which are apparent from the following disclosure and from the plant description set forth in the aforementioned application. The new variety, as such, is mainly distinguished from its antecedents and related varieties known to the inventor by a growth habit providing specimens with structural characteristics that are normally identified with plant specimens of the Hoya carnosa compacta variety and with variegated leaf blades characterized by albino border areas that surround generally solid green center fields in the upper and lower epidermal blade parts, as will be more apparent from the disclosure which follows.

The new variety appeared as a sport on a plant specimen of the Hoya carnosa compacta variety which was under cultivation in a nursery at Winter Garden, Fla., and since the initial discovery of the new variety, has been asexually reproduced by the inventor at the Winter Garden nursery by the propagation of stem cuttings taken from the original plant specimen. Through successive propagations it has been ascertained that plants of the new variety closely resemble plant specimens of the Hoya carnosa compactai variety in structural appearance but are distinguishable from this plant variety and from other related varieties known to the inventor by a growth habit which provides such structural similarity normally identifiable with plant specimens of the Hoya carnosa compacta variety and variegated leaf blades that are characterized by an albino border areas which surround generally solid green center areas in the upper and lower epidermal areas of the blade.

The accompanying drawings serve, by color photographic means, to illustrate the new variety and wherein:

FIG. 1 is a color photograph of a vine cut from a plant specimen of the new variety;

FIG. 2 is a color photograph of a plant specimen of the new variety showing immature growth at the tip of the vine of the specimen;

FIG. 3 is a color photograph showing inflorescences on a vine of the new variety with one inflorescence having flowers which have opened whereas the other inflorescence shows the flowers prior to opening; and

FIG. 4 is another color photograph of one of the inflorescences seen in FIG. 3.

The following is a detailed description of the new plant variety with colors and hues, unless otherwise clearly indicated by the text, being named in accord with the ISCC NBS method of designating colors (US. Department of Commerce, National Bureau of Standards, Circular 553, issued Nov. 1, 1955), the named colors being interpreted from color notations derived by comparison with color specimens in the current Neighboring Hues Edition of the Munsell Book of Color, published by the Munsell Color Company, Inc., of Baltimore, Md.
