HOYA CARNOSA RUBRA Fild Feb. 16, 1970 United States Patent C) 3,105 HOYA CARNOSA RUBRA Barnell L. Cobia, Winter Garden, Fla., assignor to B. L. Cobia, Inc., Winter Garden, Fla. Filed Feb. 16, 1970, Ser. No. 11,926 Int. Cl. A01h 5/00 US. Cl. Plt.88 1 Claim ABSTRACT OF THE DISCLOSURE A new and distinct plant variety of the milkweed family resembles plants of the Hoya carnosa Exotica variety in variegated leaf patterns but is distinguished from the latter variety by certain color characteristics, by slightly larger stems and by a somewhat wider leaf blade that is usually ovate in shape.

The invention relates to a new and distinct plant variety of the milkweed (Asclepiadaceae) family and which has been named the Hoya camosa (CV) Rubra 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 Exotica variety and of the Hoyw carnosa Variegata variety. A lesser known related variety found in the foliage plant market but which is rapidly gaining popularity is the Hoya carnosa Tricolor variety.

Plants of the Hoya carnosa Tricolor variety have variegated leaf blades which are similar in pattern to those of the Hoya carnosa Variegated variety but are preferred by comparing purchasers in the market place because of certain characteristic colors which, in immature and newly matured growth, appear in the albino or variegated areas of the leaf blades.

Plants of the Hoya carnosa Exotica variety have variegated leaf blades but in contrast to the albino leaf blade border areas of the Hoya carnosa Variegated plant variety are characterized by an albino center field in the leaf blade. The main object of the invention has been to develop a plant variety which is related in general appearance to the Hoya carnosa Exotica plant variety but which exhibits colors in the albino leaf blade areas that are similar to those found in the Hoya ca rn0sa Tricolor variety. 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 carnosa Exotica variety and are not only related to this variety but also related to the Hoya CLH'VIO'SLZ Variegata and Hoya carnosw Tricolor varieties. The new variety is mainly distinguished from its antecedents and related varieties known to the inventor by a combination of certain color and structural characteristics which will be apparent subsequently. The new variety appeared as a sport on a plant of the H oya carnosa Tricolor 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.

Through successive propagations, it has been ascertained that plants of the new variety generally resemble plants of the Hoya carnOsa Exotica variety but are distinguishable from this plant variety and from other related varieties known to the inventor by a growth habit which combines the following characteristics:

(1) Larger diameter stems than those of the Hoya carnosa Exotica variety and which in color are dominated by purple, purplish red, red, reddish brown and/or pink hues prior to becoming glaucous;

Plant Pat.

"ice" (2) Leaves with petioles that in color are dominated by purple, purplish red, red, reddish brown, pink and/ or yellowish pink hues prior to becoming glaucous, and with leaf blades that are somewhat broader than those of the H oya carnosa Exotica variety, that are variegated in patterns characteristic of the Hoya carnosa Exotica variety, that have an albino center area which in color is dominated during early immaturity by purplish pink, purplish red, red and/or yellowish pink hues, and that have a green border area which is overcast during early immaturity with color endowing the border area to the ordinary eye with a blackish and/or brownish appearance; and

(3) An inflorescence that has a peduncle color dominated by purplish red, red and/or reddish brown hues prior to becoming glaucous, a pedicel color dominated by purplish red and/ or red hues, a sepal color dominated by purplish red, red and/or reddish brown hues, and a petal which in color at its upper epidermal side is dominated by purplish pink and/ or pink hues and which in color at its lower epidermal side is dominated by a purplish red hue.

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

FIG. 1 is a color photograph of a plant specimen of the new variety and shows the upper epidermal sides of the leaves;

FIG. 2 is a color photograph of the specimen seen in FIG. 1 and shows the lower epidermal sides of the leaves;

FIG. 3 is a color photograph of an inflorescence of the new variety; and

FIG. 4 is another color photograph of the inflorescence 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 the color specimens in the current Neighboring Hues Edition of the Munsell Book of Color, published by the Munsell Color Company, Inc., of Baltimore, Maryland.
