| Abstract: |
A Calathea plant named `Angela` having oval leaves with a dark-green center and a pink-purple margin on young leaves. The mature leaves have a green center with dark green strips parallel to the primary veins that are bordered first by a bright silver-green margin and then by a dark green margin. The lower side of the leaves is dull purple-red. |
| Claim: |
I claim:
1. A new and distinct cultivar of Calathea plant named `Angela,` as illustrated and described. |
| Description: |
The present inventioncomprises a new and distinct cultivar of Calathea, botanically known as Calathea roseo picta, and referred to by the cultivar name `Angela.`
The new cultivar is a random mutation and was discovered and selected from a group of C. roseo picta plants in March 1989 in Schipluiden, The Netherlands, by the inventor Magdalena J. M. van Rijn.
Propagation by tissue culture at the above noted location increased the number of plants for evaluation and has demonstrated the stability of the combination of characteristics of `Angela` from generation to generation.
The following observations, measurements and values were taken at 's-Gravenzande, The Netherlands and describes plants grown in the Nursery Schipluiden under greenhouse conditions which closely approximating those generally used in horticulturalpractice.
The following traits have been repeatedly observed to be characteristics which in combination distinguish `Angela` from others of the same species.
1. The plant produces leaves with a purple mid-rib. Parallel to the primary veins are dark green strips on a light green center and both are bordered by a green colored margin. This margin has a purple blush which gets darker towards the baseof the leaf. The margin on the upper leaf surface is dotted dark green and the outermost margin is purple.
2. The leaf margin of young leaves is purple-red which becomes dark green as the leaf matures.
3. The lower side of the leaf is dull purple-red.
4. The leaf stalk from the leaf base to the geniculum is purple-red.
All color references are to The Royal Horticultural Society Colour Chart (R.H.S.). The color values were determined between 11:30 h and 12:00 h on Apr. 7, 1995 under natural light with a light intensity of 1210 J/m.sup.2 at 's-Gravenzande, TheNetherlands.
Phenotypic characteristics may vary somewhat depending on horticultural practices such as light level and fertilization rate, among others, without, however, any variance in genotype.
The accompanying color photographic drawings show an`Angela` that is 9.5 months old grown in a 19 cm pot.
Sheet 1 is a top perspective of the plant.
Sheet 2 and 3 are a top/side and side perspective of `Angela`, respectively.
Sheet 4 shows the upper surface of a young leaf of the plant.
Sheets 5 and 6 show the upper surface of young to mature leaves of `Angela. `
Finally, sheet 7 shows the upper surface of a mature leaf of `Angela.`
