USPP36628P2 - Rhaphidophora plant named ‘TUXRAP1’ - Google Patents

Abstract

A new and distinct Rhaphidophora plant named ‘TUXRAP1’ particularly distinguished by its unique and uniformly mottled leaf variegation pattern colored yellowish grey.

Description

Genus and species: Rhaphidophora decursiva.

Variety denomination: ‘TUXRAP1’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Rhaphidophora plant, botanically known as Rhaphidophora decursiva, and hereinafter referred to by its name ‘TUXRAP1’. The genus Rhaphidophora is closely related to the genera Philodendron and Monstera. Rhaphidophora are tropical climbing plants native to Southeast Asia.

The new Rhaphidophora cultivar ‘TUXRAP1’ is a naturally-occurring, whole plant mutation discovered by the inventor in a cultivated population of unnamed commercially grown Rhaphidophora decursiva plants (unpatented). The new Rhaphidophora cultivar ‘TUXRAP1’ was discovered in September 2021 by the inventor in a commercial shade house located in Miami, Florida. The inventor selected ‘TUXRAP1’ as a single plant within a large population of cultivated Rhaphidophora plants due to its unique variegated foliage pattern.

Plants of the new Rhaphidophora cultivar ‘TUXRAP1’ and plants of the unnamed commercial and parent Rhaphidophora cultivar differ in that the parent cultivar has solid green leaves, whereas ‘TUXRAP1’ has variegated leaves. Asexual reproduction of ‘TUXRAP1’ by vegetative stem divisions was first performed in October 2021 in Miami, Florida. Asexual reproduction of the new Rhaphidophora cultivar ‘TUXRAP1’ has shown that the unique features are stable and reproduced true-to-type through 10 successive generations.

Plant Breeder's Rights for this variety have not been applied for. ‘TUXRAP1’ has not been made publicly available or sold anywhere in the world more than one year prior to the effective filing date of this application.

SUMMARY OF THE INVENTION

The new Rhaphidophora cultivar has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, light intensity, water status, fertilizer rate and type, without, however, any variance in genotype.

The most outstanding and distinguishing characteristic of the new Rhaphidophora plant ‘TUXRAP1’ is its unique and uniformly mottled leaf variegation pattern colored yellowish grey. This unique feature distinguishes ‘TUXRAP1’ as a new and distinct variety of Rhaphidophora decursiva.

DESCRIPTION OF THE FIGURES

This new Rhaphidophora cultivar ‘TUXRAP1’ is illustrated by the accompanying-colored photographs which show the overall appearance and distinct characteristics of the plant. The colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of a 1-year-old plant grown in a 3-gallon container in a commercial shade house in Miami, Florida under 73 percent light exclusion. Colors in the photographs may differ slightly from the color values cited in the botanical description which accurately describes the colors of the new variety.

DESCRIPTION OF THE NEW VARIETY

In the following description, color references are made to The Royal Horticultural Society Colour Chart, Sixth Edition, except where general color terms of ordinary dictionary significance are used.

The following observations and measurements describe plants grown in a commercial shade house in Miami, Florida under 73 percent light exclusion. Detailed descriptions were taken in September 2024 from 1-year-old plants grown in 3-gallon containers. Measurements and numerical values represent averages of typical plant types.

DETAILED BOTANICAL DESCRIPTION

• Classification:
  • • Family.—Araceae.
    • Botanical.—Rhaphidophora decursiva.
    • Common.—Dragon tail plant.
    • Denomination.—‘TUXRAP1’.
• General description:
  • • Plant type.—Tropical perennial.
    • Growth habit.—Prostrate when grown in containers without artificial support but can be trained to grow vertically with artificial support.
    • Growth rate.—Growth rate depends on time of year and light intensity, but generally 2-inches of stem growth per month during the winter months in south Florida and 4-inches of stem growth during the summer months in south Florida.
    • Propagation type.—Vegetative stem divisions.
    • Time to initiate roots.—2 weeks during summer months.
    • Time to produce a rooted young plant.—4 weeks during summer months.
    • Roots.—Thick, white fleshy roots with fine lateral roots.
• Stems:
  • • Branching characteristics.—Monopodial with one dominant central stem, rarely branches under cultivation.
    • Aspect.—Rounded.
    • Length.—47.0 cm.
    • Width.—2.0 cm at the proximal end, tapering to 1.5 cm at the distal end.
    • Internode length.—Average 4.6 cm.
    • Strength.—Rigid and strong.
    • Texture and luster.—Smooth and shiny.
    • Color.—Main color is NN137A (greyish olive green) with faint linear striations colored 145A (strong yellow green), striations are more visible towards the distal (younger) end of the stem.
• Foliage:
  • • Quantity of leaves per plant.—Average 16 on a 1-year-old stem.
    • Arrangement.—Alternate.
    • Attachment.—Petiolate.
    • Lamina.—Shape: Pedate, deeply incised. Number of incisions: 4 to 5. Length: Approximately 20.5 cm. Width: Approximately 20.0 cm at the widest point above the base of the lamina. Orientation: Horizontal to moderately arched upwards. Aspect: Convex. Apex: Obtuse, but often moderately incised on mature leaves. Base: Slightly to moderately cordate and sometimes truncate. Margins: Deeply incised with course undulation. Texture and luster, adaxial surface: Moderately rugose, shiny on juvenile leaves and becoming more matte on mature leaves. Texture and luster, abaxial surface: Glabrous and matte. Midrib: Recessed on the upper surface and protruding on the lower surface. Venation pattern: Pinnate, veins are recessed on the upper surface and protruding on the lower surface.
