| Abstract: |
A new plant variety of Acer palmatum characterized by red sectoral leaf variegation. |
| Claim: |
I claim:
1. A new variety of Acer palmatum plant named `Fujinami Nishiki` substantially as described and illustrated. |
| Description: |
Classification:The present invention relates to a new Acer palmatum Thunb. plant.
Varietal denomination: The new plant has the varietal denomination `Fujinami Nishiki`.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct variety of Acer palmatum Thunb., which was discovered as a branch sport of an unnamed variety of Acer palmatum (unpatented) in Kawaguchi City, Saitama, Japan, by the originator, Mr. YoshimichiHirose. The varietal denomination of the new variety is `Fujinami Nishiki`.
The genus Acer is included in the family Aceraceae that comprises 2 genera of shrubs and trees native to northern temperate regions and tropical mountains. Acer comprises about 150 species of deciduous or evergreen trees and shrubs, native toNorth and Central America, Europe, North Africa and Asia.
Acer palmatum is a native of Japan and Korea. Acer palmatum generally has 5 to 7 lobed, palmate leaved, lobes that are deeply divided, lanceolate to oblong, biserrate, cuspidate. Petioles are approximately 4 cm long.
SUMMARY OF THE INVENTION
The new variety was discovered as a branch sport and differs from other cultivars known to the inventor by its red sectoral leaf variegation. Asexual reproduction of the new variety by grafting conducted in Saitama Prefecture, Japan and ForestGrove, Oreg., has confirmed that the distinctive characteristics of the new variety are stable and transmitted to succeeding generations and that the new variety reproduces true to type.
COMPARISON WITH PARENT
`Fujinami Nishiki` is distinguished from its parent and all other varieties of Acer palmatum of which I am aware by its red sectoral leaf variegation. In contrast, the parent of `Fujinami Nishiki` exhibits all red foliage.
BRIEFDESCRIPTION OF ILLUSTRATION
The accompanying photographic illustration shows a plant of the new cultivar as true to color as is reasonably possible to make in an illustration of this character.
This illustration shows the distinctive leaf variegation of the new variety.
DESCRIPTION OF THE NEW VARIETY
Acer palmatum `Fujinami Nishiki` has not been observed under all possible environmental, cultural and light conditions. The following observations and descriptions are of 4 year-old plants grown in 5-gallon nursery containers in Forest Grove,Oreg., Lewisberry, Pa., and Kawaguchi City, Saitama, Japan. Phenotypic expression may vary with light intensity, cultural, and environmental conditions. In this description, color references are to The Royal Horticultural Society Colour Chart (2001)and terminology used in the color descriptions herein refers to plate numbers in this color chart. As with many plants in the Aceraceae family, phenotypic characteristics can be dramatically different in terms of growth morphology.

Leaf Color: Varies withintensity of sunlight and cultural conditions; the following color readings were taken in Forest Grove, Oreg. of a 4 year-old specimen grown in 5 gallon nursery containers. Upper side: Ground color near Purple Group 79A to 79B; variegation near RedGroup 50A. Underside: Ground color near Purple Group 79A to 79B; variegation near Red Group 50B.
