MILKWEED PLANT FAMILY Filed March 13, 1969 2 Sheets-Sheet 2 United States Patent 3,054 MILKWEED PLANT FAMILY Barnell L. Cobia, Winter Garden, Fla., assignor to B. L. Cobia, Inc., Winter Garden, Fla. Filed Mar. 13, 1969, Ser. No. 808,025 Int. Cl. A01h /00 US. Cl. Plt.-88 1 Claim ABSTRACT OF THE DISCLOSURE A new plant variety of the milkweed family closely resembles the Hoya carnosa compacta variety in structural appearance but is distinguishable from this variety by a more compact growth habit, leaf blades which are distinctively variegated and by certain color characteristics.

The invention relates to a new and distinct plant variety of the milkweed (Asclepiadaceae) family. The new variety has been developed from a sport that appeared as a bud variation on a cultivated plant specimen of the Hoya carnosa compacta variety and has been named the Hoya carnosa compacta. Mauna Loa by the inventor.

Plant specimens of the Hoya carnosa compacta variety have become popular in the foliage plant market and with the natural preference that the public has for plant specimens which have variegated leaves, a principal objective of the invention has been to develop a new plant variety which is structurally similar in appearance to the Hoya carnosa compacta variety but which is nevertheless distinguishable from the latter by variegated leaf blade characteristics. This objective has been fully realized by the invention as will be apparent from the plant description contained herein.

The sport was discovered on a plant specimen of the Hoya carnosa compacta variety which was under cultivation at a nursery at Winter Garden, Fla., and the new variety has been asexually reproduced at the same nursery by the propagation of stem cuttings taking from the sport.

The new plant variety is distinguishable from the Hoya carnosa compacta variety by the distinctive characteristics enumerated below and is distinguishable from other antecedents and known related varieties by a growth habit which provides specimens of the new variety which are structurally closely similar in appearance to plant specimens of the Hoya carnosa compacta variety but which are nevertheless distinguishable therefrom by the following distinctive characteristics:

(1) A more compact growth habit.

(2) Lighter appearing stems which in color are characterized by hues which predominantly range from pink to orange yellow in fully matured stems.

(3) Lighter appearing petioles which in color are characterized by hues which predominantly range from olive to yellow green in fully matured leaves.

(4) Variegated leaf blades which at the upper epidermis side are distinctively characterized by a green border area that surrounds an albino center field which has green blotches that are lighter in color than in the border area and tend to concentrate along the surrounding border area, and which at the lower epidermis side are distinctively characterized by a field with green blotches that tend to concentrate along the margins of the leaf blade.

(5) An inflorescence "with a peduncle which characteristically is grayish red and/ or moderate red, with pedicels that are characteristically dark pink in color, and

wlth sepals that are characteristically moderate red and/ or grayish red.

Patented Aug. 10, 1971 The accompanying drawings serve by color photographic means to illustrate the new variety and wherein;

FIG. 1 shows a plant specimen which is in bloom.

FIG. 2 is an enlarged photograph of a stem section, and

FIG. 3 is an enlarged photograph showing a bloom.

The following is a detailed description of the new variety and is based on observations of well fertilized specimens which were grown in the Central Florida area under shaded nursery conditions and where tem eratures range from about 60 F. to about 85 F. during the winter months and from about 75 F. to about F. during the summer months. Except where general terms of ordinary dictionary significance are obviously used, color terminology and color designations reported herein are in accord with the ISCC-NBS method of designating colors as described in the US. Department of Commerce, National Bureau of Standards, Circular 553, entitled The ISCC-NBS Method of Designating Colors and a Dictionary of Color Names with the color designations having been derived through interpretation of Munsell Color Notations obtained by comparing plant specimens with color specimens in the current Neighboring Hues Edition of the Munsell Book of Color, published by Munsell Color Company, Inc. of Baltimore, Md. and to which the reported color notations (Munsell Hue Munsell Value/Munsell Chroma) are referenced.
