ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Fern plant, botanically known as
Nephrolepis exaltata
, and hereinafter referred to by the cultivar name Regina.
The new cultivar was discovered by the Inventor in Malaga, Spain, as a naturally-occurring somaclonal variant in a population of tissue-cultured plants of an unnamed selection of
Nephrolepis exaltata.
Since 1988, asexual reproduction by tissue culture of the new cultivar at Malaga, Spain, has shown that the unique features of this new Fern are stable and retained through more than 100 successive generations of asexual reproduction.
SUMMARY OF THE INVENTION
The new Fern 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 regime, without, however, any variance in genotype. The following observations, measurements and comparisons describe plants grown in Apopka, Fla., under conditions generally used in commercial practice.
The following traits have been repeatedly observed and are determined to be the unique characteristics of Regina. These characteristics in combination distinguish Regina as a new and distinct cultivar:
1. Upright and outwardly arching plant habit; symmetrical, rounded and uniform; plants roughly spherical.
2. Relatively compact growth habit.
3. Rapid growth rate.
4. Appropriate for smaller containers and hanging baskets.
5. Durable rachis; plants resist breakage during shipping.
6. Numerous pinnae per frond that are dark green, glossy, curly with finely crenate margins.
7. Closely-spaced pinnae; densely foliated.
The new fern is most similar to its parent cultivar, the unnamed selection of
Nephrolepis exaltata
. However in side-by-side comparisons conducted in Apopka, Fla., the new Fern differs from the unnamed selection of
Nephrolepis exaltata
in the following characteristics:
1. Plants of the new Fern are more compact, more symmetrical and uniform in plant habit than plants of the unnamed selection of
Nephrolepis exaltata.
2. Rachis are shorter, stronger and more durable on plants of the new Fern compared to plants of the unnamed selection of
Nephrolepis exaltata.
3. Pinnae are smaller, darker green and curlier on plants of the new Fern compared to plants of the unnamed selection of
Nephrolepis exaltata.
4. Pinnae are more numerous and more closely-spaced on plants of the new Fern than on plants of the unnamed selection of
Nephrolepis exaltata
which give a more densely foliated appearance to the new Fern.
