Cobia, Inc., Winter Garden, Fla., a corporation of Florida Filed July 31, 1968, Ser. No. 749,220 Int. Cl. Aillh /00 US. Cl. Flt-88 1 Claim ABSTRACT OF Til-IE DISCLQSURE A new and distinct plant variety of the milkweed family developed from a mutation that appeared on a plant of the Hoya Carnosa Exotica variety is distinguished from its antecedents and known related varieties by a growth habit which combines the following distinctive characteristics:

(1) Leaf blades which have a solid green field and are broader in comparison to the parent variety, and which are wrinkled in appearance by dimples or depressions that occur in the upper surface of the leaf blade at opposite sides of midrib and with the depressions or dimples usually numbering from 6 to in each blade,

(2) Stems, peduncles, and pedicels which are thicker in comparison to the parent variety and with the lengths of the peduncles and distances between nodes being shorter in comparison to the parent variety,

(3) Stems and peduncles which in color range from moderate olive brown to grayish reddish brown,

(4) Petioles which in color range from moderate olive to moderate yellow green, and

(5) Pedicels which in color range from strong brown to grayish reddish orange.

The invention relates to a new and distinct plant variety of the milkweed (Asclepiadaceae) family which has been developed from a mutation that appeared on the plant of the H oya Carnosa ExOtica variety.

The principal objective of the invention has been to develop a healthy robust appearing new plant variety for the foliage plant market and which is related to the H oyw Carnosa Exotica variety and distinguishable from it and other related varieties that are currently being offered in the market place.

The new variety, in constrast to the growth habit of its parent, has a healthier more robust appearance. This is in part attributed to a growth habit which provides somewhat thicker stems that have a shorter distance between nodes than the parent and which also provides broader leaf blades that have a solid green field in contrast to the variegated type leaf blade found in the parent variety.

The new variety has been asexually reproduced in a nursery at Leesburg, Fla., by the propagation of stem cuttings taken from the mutation. Through successive propagations, the new variety has been found to be distinguishable from its antecedents and related varieties known to the inventor by a growth habit which combines the following distinctive characteristics:

(1) Leaf blades which have a solid green field and are broader in comparison to the parent variety and which are wrinkled in appearance by dimples or depressions that occur in the upper surfaces of the leaf blade at opposite sides of midrib and with the depressions or dimples usually numbering from six to ten in each blade,

(2) Stems, peduncles and pedicels which are thicker in comparison to the parent variety and with the lengths VII Fatented Dec. 8, 197%) ice of the peduncles and distances between nodes being shorter in comparison to the parent variety,

(3) Stems and peduncles which in color range from moderate olive brown to grayish reddish brown,

(4) Petioles which in color range from moderate olive to moderate yellow green, and

(5) Pedicels which in color range from strong brown to grayish reddish orange.

The accompanying drawings serve by color photographic means to illustrate the new variety and wherein; FIG. I shows a potted specimen of the new variety,

FIG. II shows a stern together with a peduncle and attached pedicels of an infloresence of a specimen of the new variety,

FIG. III shows a flower cluster of a specimen, and

FIG. IV is an enlargement of some of the flowers shown in FIG. Ill.

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 temperatures 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 lSCC-NBS method of designating colors as described in the US. Department of Commerce, National Bureau of Standards, Circular 553, entitled The ISCONBS 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 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.

In contrast to the open leaf blade characteristics of the new variety and which are evident in FIG. 1, leaf blades of the Hoya Carnosa Compacta variety are distinguishable in that they have strong conduplicate and recurved tendencies which commonly result in nearly closed blades with bent midribs that draw the apices of the blades toward the plant stem. Among other characteristics which distinguish plants of the new variety from those of the Hoya Carnosa Compacta variety are those providing longer and larger diameter pedicels in plants of the new variety, as well as flowers of a greater diameter than those of the Hoya Carnosa Compacta variety.

I claim:

1. The new and distinct variety of the milkweed family, substantially as herein shown and described, characterized in particular as to novelty by a growth habit that combines the following distinctive characteristics:

(1) leaf blades which have a solid green field and are wrinkled in appearance by depressions at opposite sides of the midrib that usually number from six to ten in each mature blade and which are broader in comparison to leaf blades of the Hoya Carnosa Exotica variety,

(2) stems, peduncles and pedicels which are thicker in comparison to those of the Hoya Carnosa Exotica variety and with the peduncle lengths and internode distances being shorter in comparison to those of the H oya Carnosa Exotica variety,

(3) stems and peduncles which in color range from moderate olive brown to grayish reddish brown,

(4) petioles which in color range from moderate olive to moderate yellow green, and

(5) pedicels which in color range from strong brown to grayish reddish orange.
