GENUS AND SPECIES
Anthurium andreanum L.
VARIETY DENOMINATION
‘ANTHINFAM’
BACKGROUND OF THE NEW PLANT
The present invention comprises a new and distinct variety of Anthurium, botanically known as Anthurium andreanum L., and hereinafter referred to by the variety name ‘ANTHINFAM’. The new variety originated from a hybridization made in November 2000 in Bleiswijk, The Netherlands. The female parent is a light green Anthurium plant designated ‘1535-02’ (unpatented), while the male parent was a cream Anthurium plant designated ‘00-271’ (unpatented).
A single plant was selected in May 2003 and has been asexually reproduced repeatedly by tissue culture in Bleiswijk, The Netherlands over a five-year period. The present invention has been found to retain its distinctive characteristics through successive asexual propagations.
Plant Breeder's Rights for this variety have been applied for in Europe on Jan. 14, 2013. ‘ANTHINFAM’ has not been made publicly available or sold anywhere in the world more than one year prior to the filing of this application.
SUMMARY OF THE INVENTION
The following are the most outstanding and distinguishing characteristics of this new variety when grown under normal horticultural practices in Bleiswijk, The Netherlands.
1) Green spathes very well suited for cutflower culture;
2) White spadix with green tip;
3) Little shoot formation;
4) Tall plant habit; and
5) Dark green healthy foliage.
DESCRIPTION OF THE PHOTOGRAPHS
This new Anthurium plant is illustrated by the accompanying photographs which show the overall plant habit including blooms, buds and foliage of the plant; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of a 300-week old plant grown in a greenhouse in Bleiswijk, The Netherlands in 2014.

FIG. 3 shows a close-up of the upper surface of the mature leaf.
DESCRIPTION OF THE NEW VARIETY
The following detailed description sets forth the distinctive characteristics of ‘ANTHINFAM’. The data which define these characteristics were collected from asexual reproductions carried out in Bleiswijk, The Netherlands. The plant history was taken on 300-week old plants which were planted from tissue culture in 7-centimeter pots and grown in a glass greenhouse between 19° C. and 24° C. Observations were made in February 2014. Color readings were taken under 5000 lux natural light in the greenhouse. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2001).

- Longevity of the flower as a cut flower.—40 days to 45 days.
- Spathe:
- Buds.—The spathe is tightly rolled around the spadix and extrudes from the peduncle sheath. After the spathe is fully open the peduncle elongates some extra centimeters.
- Arrangement.—Spathe angle with the peduncle is between 80 degrees and 100 degrees; the spathe stands on a wiry peduncle about 10 cm to 20 cm above the foliage.
