The International Nepenthes Grex Registry

There are minimal requirements in order to register a grex:

  1. You must know and be able to provide a pictorial description of the parent plants. In some cases where parent photos cannot be obtained, a written description may be accepted.

  2. You must be able to provide a pictorial description of some representatives of the grex registered.

  3. You should not attempt to register a grex until such time as you are certain of its survival and can provide a description of, at least, consistent lower pitcher morphology. This would generally be two to three years from the time of germination.

To submit a grex for registration, please see our submission procedure here.
