Abstract

A new and distinct cultivar of Aglaonema named `Black Lance`particularly characterized by its tall, upright and freely branching plant habit; long and narrow tri-colored leaves centrally marked with two shades of silver green; rapid growth rate; and resistant to diseases common to Aglaonema.

Description

The present invention relates to a new and distinct cultivar of Aglaonema plant, botanically known as Aglaonema hybrida, and hereinafter referred to by the cultivar name Black Lance.
The new cultivar is a product of a planned breeding program conducted by the inventor in Valkaria, Fla. The new cultivar originated from a cross by the inventor between the species Aglaonema simplex as the female, or seed, parent with the nonpatented cultivar Aglaonema hybrida `Ernesto's Favorite`. The cultivar Black Lance was discovered and selected by the inventor in August, 1988, as a plant within the progeny of the stated cross in a controlled environment in Valkaria, Fla.
Asexual propagation of the new cultivar by divison Valkaria, Fla., has shown that the unique features of this new Aglaonema plant are stable and reproduced true to type in successive generations of asexual propagation.
The new Aglaonema has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity and fertilizer rate, without, however, any variance in genotype. The following observations, measurements and comparisons describe plants grown in Zolfo Springs, Fla., under a polypropylene-covered shadehouse and conditions which closely approximate those used in horticultural practice.
The following traits have been repeatedly observed and are determined to be the unique characteristics of `Black Lance`. These characteristics in combination distinguish `Black Lance` as a new and distinct cultivar:
1. Plants of the new Aglaonema are relatively tall, upright and freely branching.
2. The leaves of the new Aglaonema are relatively long and narrow.
3. The abaxial leaf surfaces of plants of the new Aglaonema are marked with three shades of green. The base color is very dark green and the center of the leaf is silver green with lighter silver green chevrons which follow the primary veins.
4. Plants of the new Aglaonema have a rapid growth rate.
5. Plants of the new Aglaonema are exceptionally resistant to diseases common to Aglaonema.
Plants of the new Aglaonema can be compared to plants of the Aglaonema cultivar Rhapsody in Green (disclosed in U.S. Plant Pat. No. 8,975) which have a similar leaf color pattern and growth habit. However, leaves of plants of the new Aglaonema are marked with three shades of green, and are much darker green in base color compared to leaves of plants of the cultivar Rhapsody in Green that have lighter green bi-colored leaves. In addition, plants of the new Aglaonema are more freely branching than plants of the cultivar Rhapsody in Green.
The accompanying colored photographs illustrate the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type.
The first photograph comprises a top perspective view of a typical single plant of `Black Lance` in a 26-cm container about 16 months after planting a single four-leaf cutting.
The second photograph comprises a close-up view of the abaxial (left) and adaxial (right) surfaces of a mature leaf and illustrates the detail of the leaf color pattern. Leaf colors in the photographs may appear different from the actual colors due to light reflectance.
In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used.

Primary veins: The primary veins are sunken on the abaxial surface and are slightly prominent on the adaxial surface. The primary veins are the same color as the tissue surrounding them. The leaf blade is convex between the primary veins. Pattern: The abaxial leaf surface is marked with three shades of green. The base color of the leaf is very dark green, the center of the leaf is silver green with lighter silver green chevrons which follow the primary veins.
