| Abstract: |
A distinct cultivar of Fern plant named Glowstar, characterized by its outwardly arching plant habit that is symmetrical in form; compact habit and low vigor; suitability for small pots; black rachis color; numerous pinnae per frond; short, narrow and finely serrated pinnae; and dark green and glossy pinnae. |
| Claim: |
It is claimed:
1. A new and distinct cultivar of Fern plant named Glowstar, as illustrated and described. |
| Description: |
The present inventionrelates to a new and distinct cultivar of Fern plant, botanically known as Pellaea falcata, and hereinafter referred to by the cultivar name Glowstar.
The new cultivar was discovered by the inventor in Aalsmeer, Holland, as a naturally occurring mutation in a population of 100 plants of the species Pellaea falcata.
Asexual reproduction by tissue culture of the new cultivar at Aalsmeer, Holland, has shown that the unique features of this new Fern are stabilized and retained through more than twenty successive generations of asexual reproduction.
The new Fern has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype. The followingobservations, 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 Glowstar. These characteristics in combination distinguish Glowstar as a new and distinct cultivar:
1. Outwardly arching plant habit that is symmetrical in form.
2. Compact habit and low vigor.
3. Suitable for small pots.
4. Black rachis color.
5. Numerous pinnae per frond.
6. Short, narrow and finely serrated pinnae.
7. Dark green and glossy pinnae.
The new Fern is most similar to its parent cultivar, the species Pellaea falcata. The new Fern differs from the species Pellaea falcata in the following characteristics:
1. Plants of the new Fern have an outwardly arching plant habit that is symmetrical in form compared to the more upright and nonsymmetrical plant habit of plants of the species Pellaea falcata.
2. Plants of the new Fern are more compact and have a low vigor compared to plants of the species Pellaea falcata. The growth rate of plants of the species Pellaea falcata is twice as fast as the growth rate of plants of the new Fern.
3. Rachis length is longer on plants of the new Fern compared to plants of the species Pellaea falcata, however the rachis width is narrower.
4. Rachis color is darker on plants of the new Fern compared to plants of the species Pellaea falcata.
5. Pinnae are shorter, narrower, and more numerous on plants of the new Fern compared to plants of the species Pellaea falcata.
6. Pinnae margin is finely serrated on plants of the new Fern and entire on plants of the species Pellaea falcata.
7. Pinnae are ovate in shape on plants of the new Fern and obovate on plants of the species Pellaea falcata.
8. Pinnae are very glossy on plants of the new Fern whereas pinnae are dull and without gloss on plants of the species Pellaea falcata.
A detailed comparison of the new Fern and the species Pellaea falcata appears in Chart A at the end of the specification.
The accompanying colored photograph illustrates the overall appearance of the new cultivar, showing the colors astrue as it is reasonably possible to obtain in colored reproductions of this type. The photograph comprises a top perspective view of a typical potted plant of Glowstar.
In the following description, color references are made to The RoyalHorticultural Society Colour Chart except where general terms of ordinary dictionary significance are used. Measurements and numerical values represent averages for six typical plants.
