Abstract
A new and distinct Haworthia hybrid plant named ‘AMIHAW1616’, which is characterized by spirally-arranged, dark green and glossy foliage with near-white orbicular protuberances arranged in irregular transverse rows across the upper and lower leaf surfaces and small near-white teeth along the length of the margins. 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 Haworthia limifolia x Haworthia pentagona.
Variety denomination: The inventive variety of Haworthia hybrid disclosed herein has been given the variety denomination ‘AMIHAW1616’.
This application claims priority to the Community Plant Variety Rights application number 2018/1404, filed May 29, 2018, which is herein incorporated by reference.
Parentage: ‘AMIHAW1616’ is a seedling selection resulting from the controlled pollination of an unnamed Haworthia limifolia plant (not patented), the seed parent, with Haworthia pentagona ‘AMIHAW1801’ (U.S. Pat. No. 30,399), the pollen parent. The crossing was made by the inventor in the autumn of 2011 at a commercial greenhouse in Heerhugowaard, the Netherlands. In the autumn 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, ‘AMIHAW1616’.
Asexual Reproduction: Asexual reproduction of the new cultivar ‘AMIHAW1616’, by way of rooting leaf cuttings, was first initiated in the summer of 2015 at the inventor's commercial greenhouse in Heerhugowaard, the Netherlands. Through four subsequent generations, the unique features of this cultivar have proven to be stable and true to type.
The cultivar ‘AMIHAW1616’ 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 ‘AMIHAW1616’. These characteristics in combination distinguish ‘AMIHAW1616’ as a new and distinct Haworthia hybrid cultivar:
-
- 1. ‘AMIHAW1616’ exhibits spirally-arranged succulent foliage in a basal rosette; and
- 2. ‘AMIHAW1616’ exhibits foliage with small, near-white teeth along the length of the margins; and
- 3. ‘AMIHAW1616’ exhibits dark green, glossy foliage with near-white orbicular protuberances arranged in irregular transverse rows across the upper and lower leaf surfaces.
The following observations and measurements made in December of 2018 describe averages from a sample set of six specimens of 12 months old ‘AMIHAW1616’ plants grown in 12 cm nursery containers at commercial greenhouse in Heerhugowaard, the Netherlands. Plants were produced using conventional greenhouse production protocols for Haworthia plants 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 after propagation and later exposed to full sun once they began to mature. 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. ‘AMIHAW1616’ 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).
A botanical description of ‘AMIHAW1616’ and a comparison with the parents and closest known comparator is provided below.
