Register Schlumbergera

Please note the following important information: 

  1. New applications for registration must comply with the International Code of Nomenclature for Cultivated Plants (ICNCP) regulations. If not, they are rejected.
  2. Only a completely and correctly filled out form can be processed.
  3. There is no claim for inclusion in the list. The application should be accompanied by at least two photos (preferably one close-up of the flower, one of the entire cultivar). The registrant allows the authors of The International Schlumbergera and Rhipsalidopsis List of Species and Hybrids to publish these photos in the context of the Rhipsalidopsis list, in whatever form.
  4. The applicant warrants that he is entitled to register the cultivar and that it is not a cultivar already known or already registered in the list.
  5. If the registrant is not the hybridizer, he confirms to have the allowance of hybridizer to register the cultivar.
  6. All sizes are in centimeters.
  7. The new cultivar should have at least flowered for the third year, before registering.
  8. The registration in this registry does not imply the creation of Plant Breeder’s Rights, patents or other rights to a name (principles 5 and 6 ICNCP).


  1. Flower size is measured as followed:


  1. The types are defined as followed: 

B – Buckleyi Type, which can be an interspecific hybrid of S. russelliana and S. truncata. It can also be any cultivar showing crenate phylloclades and symmetrical to near symmetrical flowers similar to S. russelliana and three to four ridged ovaries and fruit.

BT – Mainly Buckleyi traits or russelliana traits. The BT type have slightly asymmetrical to very zygomorphic flower form with pinkish or greyish pollen color (as opposed to yellow with the B type). Ovary and fruit generally have 3–4 significant ridges similar to S. russelliana or S. × buckleyi.

EP S. × eprica, which is S. russelliana × S. orssichiana. The term S. × eprica was named after the E.P.R.I.C. Foundation.

N – Hybrids and cultivars which doesn’t fit to one of the other types.

O – Exotica or S. × exotica are an interspecies cross of Schlumbergera opuntioides × Schlumbergera truncata or S. × buckleyi. The segmented sections are not flat phylloclades but are 3-dimensional having 3–4 sides.

Q – Queens or S. × reginae are an interspecies cross of S. orssichiana × Truncata type cultivar or species. Queens have larger, longer phylloclades with significantly long dentation. Flowers are larger than a S. truncata type and a slight bend in the tube. Some can have more than one blooming season.

T Schlumbergera species exhibiting marginal and apex dentations on their phylloclades, upright growth habit, and asymmetrical flower form. The majority of hybrids exhibit these traits.

TB – Compared to the Buckleyi type, this type has more characteristics such as dentated, asymmetrical flower form, yellow pollen and fruit with faint ridges or smooth.

  1. Hybridizer

Hybridizer is the person who pollinated the plants. If this field is left blank, it is assumed the registrant is also the hybridizer.

  1. Grower

Grower is the person who grew the plants from seeds. If this field is left blank, it is assumed the registrant is also the grower.

  1. Distributor

The complete name of the distributor must be given. The distributor is the person or firm who brought the cultivar into commerce, or offered the plant to others for distribution. If this field is left blank, it is assumed the registrant is also the distributor.

  1. Name giver

The name giver is the person who derived the cultivar name being registered. If this field is left blank, it is assumed the registrant is also the name giver.

  1. Hybridizer’s reference

means a number or code of the hybridizer to identify the plant.
