USPP28948P2 - Aloe plant named ‘AMIAL1614’ - Google Patents

Abstract

A new and distinct Aloe aristata cultivar named ‘AMIAL1614’ which is characterized by erect foliage arranged in a basal rosette, dark green foliage which is densely covered with large white papillae and prominent spines along the margins, papillae on the abaxial leaf surface which are arranged in distinct transverse rows, and the stability of these characteristics from generation to generation.

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.

Variety denomination: The inventive variety of Aloe disclosed herein has been given the variety denomination ‘AMIAL1614’.

BACKGROUND OF THE INVENTION

Parentage: ‘AMIAL1614’ is a seedling selection resulting from the self-pollination of the species, Echeveria agavoides (unnamed unpatented plant). The crossing was made by the inventor in the autumn of 2011 at a commercial greenhouse in Heerhugowaard, the Netherlands. Seed from said cross was harvested, then germinated, and the resulting seedlings were then grown to a mature size. In summer of 2013, ‘AMIAL1614’ was selected for commercialization due to its unique foliage characteristics and growth habit.

Asexual Reproduction: Asexual reproduction of the new cultivar ‘AMIAL1614’, by way of rooting leaf cuttings, was first initiated in the summer of 2015 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 three subsequent generations, the unique features of this cultivar have proven to be stable and true to type.

SUMMARY OF THE INVENTION

The cultivar ‘AMIAL1614’ 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 ‘AMIAL1614’. These characteristics in combination distinguish ‘AMIAL1614’ as a new and distinct Aloe aristata cultivar:

• • 1. ‘AMIAL1614’ exhibits erect foliage arranged in a basal rosette; and
  • 2. ‘AMIAL1614’ exhibits dark green foliage which is densely covered with large, prominent papillae on both the adaxial and abaxial surfaces, and large prominent spines along the margins; and
  • 3. ‘AMIAL1614’ exhibits large papillae which are colored white, and occasionally bearing spines; and
  • 4. ‘AMIAL1614’ exhibits papillae on the abaxial leaf surface which are arranged in distinct transverse rows.

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 ‘AMIAL1614’.

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 ‘AMIAL1614’.

BOTANICAL DESCRIPTION OF THE PLANT

The following observations and measurements made in October of 2016 describe averages from a sample set of six specimens of 9 months old ‘AMIAL1614’ plants grown in 11 cm nursery containers at commercial greenhouse in Heerhugowaard, The Netherlands. Plants were produced using conventional greenhouse production protocols for Aloe which consisted of minimal irrigation and fertilizer applications, and chemical pest and disease control measures against mealy bug and 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. ‘AMIAL1614’ 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).
