Title: Anthurium plant named ‘Antholyl’

Description:
Genus and species:  Anthurium andreanum  L. 
   Variety denomination: ‘Antholyl’. 
   BACKGROUND OF THE NEW PLANT 
   The present invention comprises a new and distinct cultivar of  Anthurium,  botanically known as  Anthurium andreanum  L., and hereinafter referred to by the cultivar name ‘Antholyl’. The new cultivar originated from a hybridization made in 2000 in Bleiswijk, The Netherlands. The female parent was a red  Anthurium  pot plant ‘Anthepedi’ (U.S. Plant Pat. No. 18,644), while the male parent was a red  Anthurium  pot plant ‘99-1878-02’ (unpatented). 
   The new cultivar was selected in 2002 from the results of the hybridization 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&#39;s Rights for this cultivar were applied with the European Union on Jan. 26, 2007. ‘Antholyl’ has not been made publicly available 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 cultivar when grown under normal horticultural practices in Bleiswijk, The Netherlands.
         1) Bright-red, durable spathes with a typical very weakly blistered surface;   2) Dark-green glossy leaves that have a slightly undulated surface;   3) Peduncle which holds the inflorescence just above the foliage;   4) Rich shoot formation;   5) Compact plant habit;   6) Flowers early and continuously throughout the year; and   7) Is a compact potplant, with a plant height of 45 cm to 55 cm.

   DESCRIPTION OF THE NEW CULTIVAR 
   The following detailed description sets forth the distinctive characteristics of ‘Antholyl’. The data which define these characteristics were collected from asexual reproductions carried out in Bleiswijk, The Netherlands. The plant history was taken on 48-week old plants which were planted from tissue culture in 17-cm pots and grown in a glass greenhouse between 19° C. and 24° C. Observations were made in November of 2007. 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).

   COMPARISON WITH PARENTAL AND COMMERCIAL CULTIVARS 
   ‘Antholyl’ differs from the female parent ‘Anthepedi’ (U.S. Plant Pat. No. 18,644), by having bigger, slightly undulated leaves, bigger spathes and a more erect plant habit, while ‘Anthepedi’ is more compact with smaller not undulated leaves. 
   ‘Antholyl’ differs from the male parent ‘99-1878-02’ (unpatented), by not having flowers with green ears (lobes) at the base of the spathe, while ‘99-1878-02’ has flowers with green ears (lobes) at the base of the spathe. 
   ‘Antholyl’ is similar to the commercial variety ‘Anthabudon’ (U.S. Plant patent application Ser. No. 12/157,534), however, there are differences as listed in Table 1 below:
