x hybrid plant named ‘AMIAL 1601’

- NovoAmi B.V.

A new and distinct Aloe aristata x Haworthia limifolia hybrid plant named ‘AMIAL1601’, which is characterized by long, broad and thick succulent foliage, foliage arranged in multiple whorls which, together, create a tall rosette, and dark green foliage with very light green orbicular protuberances arranged in irregular, wavy transverse rows across the upper and lower leaf surfaces. The new variety has shown to be uniform and stable in the resulting generations from asexual propagation.

Description

Latin name of the genus and species: The Latin name of the genus and species of the novel variety disclosed herein is Aloe aristata x Haworthia limifolia.

Variety denomination: The inventive variety of Aloe x Haworthia hybrid disclosed herein has been given the variety denomination ‘AMIAL1601’.

BACKGROUND OF THE INVENTION

Parentage: ‘AMIAL1601’ is an intergeneric hybrid seedling selection resulting from the controlled pollination of an unnamed Aloe aristata plant (not patented), the seed parent, with an unnamed Haworthia limifolia plant (not patented), the pollen parent. The crossing was made by the inventor in the spring of 2011 at a commercial greenhouse in Heerhugowaard, the Netherlands. In the summer of 2013, one seedling was observed which exhibited unique growth and foliage characteristics. After confirming the stability of the unique characteristics first observed, the new plant was selected for commercialization and given the name, ‘AMIAL1601’.

Asexual Reproduction: Asexual reproduction of the new cultivar ‘AMIAL1601’, by way of rooting leaf cuttings, was first initiated in the summer of 2014 at the inventor's commercial greenhouse in Heerhugowaard, the Netherlands. The claimed plant has since been asexually propagated by way of meristematic tissue culture propagation. Through five subsequent generations, the unique features of this cultivar have proven to be stable and true to type.

SUMMARY OF THE INVENTION

The cultivar ‘AMIAL1601’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, 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 ‘AMIAL1601’. These characteristics in combination distinguish ‘AMIAL1601’ as a new and distinct Aloe x Haworthia hybrid cultivar:

  • 1. ‘AMIAL1601’ exhibits succulent foliage arranged in multiple whorls which, together, create a tall rosette; and
  • 2. ‘AMIAL1601’ exhibits inner whorls of foliage held upright and outer whorls of foliage held more loosely; and
  • 3. ‘AMIAL1601’ exhibits long, broad and thick foliage with an ovate shape; and
  • 4. ‘AMIAL1601’ exhibits dark green foliage with very light green orbicular protuberances arranged in irregular, wavy transverse rows across the upper and lower leaf surfaces.

BRIEF DESCRIPTION OF THE FIGURES

FIG. 2 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, the typical foliage arrangement of ‘AMIAL1601.

FIG. 3 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, the adaxial surface of the mature foliage ‘AMIAL1601’.

FIG. 4 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, the abaxial surface of the mature foliage ‘AMIAL1601’.

 BOTANICAL DESCRIPTION OF THE PLANT

The following observations and measurements made in January of 2017 describe averages from a sample set of six specimens of 14 months old ‘AMIAL1601’ plants grown in 10 cm nursery containers at commercial greenhouse in Heerhugowaard, the Netherlands. Plants were produced using conventional greenhouse production protocols for Aloe and Haworthia plants which consisted of minimal irrigation and fertilizer applications, and chemical pest and disease control measures against mealy bug, Botrytis as required. Plants were grown under approximately 50 percent shade and no photoperiodic treatments or artificial light was given to the plants.

Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. ‘AMIAL1601’ has not been observed under all possible environmental conditions. Where dimensions, sizes, colors and other characteristics are given, it is to be understood that such characteristics are approximations or averages set forth as accurately as practicable. The phenotype of the variety may differ from the descriptions set forth herein with variations in environmental, climatic and cultural conditions. Color notations are based on The Royal Horticultural Society Colour Chart, The Royal Horticultural Society, London, 2015 (sixth edition).
