Definitions

  • 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.
  • 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:
  • 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.
  • FIG. 4 is another color photograph of the inflorescence seen in FIG. 3.
  • Origin A sport on a plant of the Hoya carnosa Tricolor variety.
