| Abstract: |
A new and distinct cultivar of Zamioculcas plant named `Zamicro`, characterized by its upright and compact growth habit; relatively small leaves; and shiny dark green-colored leaves. |
| Claim: |
It is claimed:
1. A new and distinct Zamioculcas plant named `Zamicro` as illustrated and described. |
| Description: |
Botanical designation:Zamioculcas zamiifolia.
Cultivar denomination: `Zamicro`.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Zamioculcas, botanically known as Zamioculcas zamiifolia, and hereinafter referred to by the name `Zamicro`.
The new Zamioculcas is a naturally-occurring whole plant mutation of an unidentified selection of Zamioculcas zamiifolia. The new Zamioculcas was discovered and selected by the Inventor as a single plant from within a population of plants of theparent selection in a controlled environment in Aarlanderveen, The Netherlands in 2002.
Asexual reproduction of the new Zamioculcas by vegetative cuttings in a controlled environment in Aarlanderveen, The Netherlands, has shown that the unique features of this new Zamioculcas are stable and reproduced true to type in successivegenerations.
SUMMARY OF THE INVENTION
The cultivar Zamicro has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature, daylength and light intensity without, however,any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of `Zamicro`. These characteristics in combination distinguish `Zamicro` as a new and distinct cultivar of Zamioculcas: 1. Upright andcompact growth habit. 2. Relatively small leaves. 3. Shiny dark green-colored leaves.
Plants of the new Zamioculcas can be compared to plants of the parent selection. Plants of the new Zamioculcas differ from plants of the parent selection in the following characteristics: 1. Plants of the new Zamioculcas are more compact andshorter than plants of the parent selection. 2. Plants of the new Zamioculcas have smaller leaves than plants of the parent selection.
Plants of the new Zamioculcas can be compared to plants of the Zamioculcas zamiifolia cultivar ZZ, not patented. In side-by-side comparisons conducted in Aarlanderveen, The Netherlands, plants of the new Zamioculcas differed from plants of thecultivar ZZ in the following characteristics: 1. Plants of the new Zamioculcas were more compact and shorter than plants of the cultivar ZZ. 2. Plants of the new Zamioculcas had smaller leaves than plants of the cultivar ZZ.
BRIEF DESCRIPTIONOF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Zamioculcas showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightlyfrom the color values cited in the detailed botanical description which accurately describe the colors of the new Zamioculcas.
The photograph on the first sheet comprises a side perspective view of a typical plant of `Zamicro` grown in a container.
The photograph on the second sheet is a close-up view of a typical branch of `Zamicro`.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations, measurements and values describe plants of the new Zamioculcas grown in Aarlanderveen, The Netherlands in a glass-covered greenhouse during the winter and spring and under conditionswhich closely approximate commercial production. During the production of the plants, day temperatures ranged from 20.degree. C. to 30.degree. C., night temperatures ranged from 18.degree. C. to 22.degree. C. and light levels averaging 100 kilolux. Plants had been growing in 8.5-cm containers for about seven months when the photographs and the description were taken. In the detailed description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except wheregeneral terms of ordinary dictionary significance are used. Botanical classification: Zamioculcas zamiifolia cultivar Zamicro. Parentage: Naturally-occurring whole plant mutation of an unidentified selection of Zamioculcas zamiifolia. Propagation:Type.--By vegetative cuttings. Time to initiate roots, summer.--About three weeks at temperatures of 20.degree. C. to 30.degree. C. Time to initiate roots, winter.--About one month at temperatures of 20.degree. C. to 25.degree. C. Time to produce arooted young plant, summer.--About 20 weeks at temperatures of 22.degree. C. to 30.degree. C. Time to produce a rooted young plant, winter.--About 29 weeks at temperatures of 20.degree. C. to 25.degree. C. Root description.--Medium in thickness tothick, fleshy; white to light brown in color. Rooting habit.--Freely branching; dense. Plant description: Plant habit.--Upright and compact growth habit; narrow inverted triangle. Stemless; pinnately compound leaves developing in basal rosettes;typically about three basal rosettes develop per plant. Appropriate for 8.5-cm and larger containers. Low vigor. Plant height.--About 23 cm. Plant diameter.--About 20 cm. Foliage description: Arrangement.--Pinnately compound; about three to fourleaves per basal rosette each with about ten leaflets; leaflets sessile. Leaves.--Length: About 20.4 cm. Width: About 7 cm. Petiole diameter, base: About 9 mm. Petiole diameter, at the lowermost leaflet: About 4 mm. Petiole texture: Smooth,glabrous. Petiole color: Close to 148A. Leaflets.--Length: About 4.6 cm. Width: About 1.7 cm. Thickness: About 0.6 mm. Shape: Elliptic; slightly concave. Apex: Acute. Base: Attenuate. Margin: Entire. Texture, upper and lower surfaces: Glabrous,smooth; thick, glossy. Venation pattern: Pinnate. Color: Developing leaflets, upper surface: Close to 143A. Developing leaflets, lower surface: Between 143B and 144A. Fully expanded leaflets, upper surface: Between 137A and 147A; venation, close to146B. Fully expanded leaflets, lower surface: Close to 137B; venation, 146B. Flower description: Flower development has not been observed. Temperature tolerance: Plants of the new Zamioculcas have been observed to tolerate temperatures from about18.degree. C. to about 32.degree. C. Pathogen/pest resistance: Plants of the new Zamioculcas have not been observed to be resistant to pests and pathogens common to Zamioculcas.
