The Name Agave gilberti ( Berger ) has priority in nomenclature over Agave bakeri ( Hooker ex Watson )

In 1981 we found in the seed list of Crista’s Cactus, U.S.A. seeds with the name Agave colimana-196. The seedlings grew very well, but after two years we came to the conclusion that the seedlings could not belong to the taxon Agave colimana because the leaves were straight and toothless. At that time the plants looked more like Agave attenuata.

On his first trip to Mexico in 1987 Bernd Ullrich had visited the habitat of Agave attenuata and Agave pedunculifera. I was still hoping that maybe my seedlings of Agave colimana-196 were actually Agave pedunculifera or Agave attenuata, but when I looked at the pictures from those plants in habitat I came to the conclusion that my Agave colimana-196 was definitely not Agave colimana but at the same time not Agave attenuata or Agave pedunculifera either.
The first time I saw a picture of “my “ Agave colimana-196 was in the colour-appendix in the 1988 reprint of Berger’s “Die Agaven” as picture 17. This picture was taken by Max Wieland in Pforzheim in the garden of Bernd Ullrich’s parents. It is not possible to read the label in that picture. Max Wieland himself owns a small nursery and these plants are available there, incorrectly labelled as Agave pedunculifera.
In 1990 I started my research to discover the origin of these seeds , wrongly named Agave colimana-196. The seed dealer from Christa’s Cactus informed me that the seeds had originated from Dudley B. Gold from Cuernavaca Mexico, owner of a big succulent collection based in his garden.
My friend Bernd Ullrich also tried to research this subject and wrote a letter to Mr.Gold, but unfortunately his research came to a sudden halt with the untimely death of this gentleman.

So What Is My Agave Colimana-196 ?
My seedlings continued to grow very well and in the winter/spring of 1998/1999 the first plant started flowering. Only one plant was harvested from the seeds but in the summer of 1999 the plant produced many bulbils in the flower stalk. I took many pictures of the plants and flowers and discussed the matter with Bernd Ullrich and from these deliberations arose for the first time the idea that this plant perhaps represented the old Agave bakeri ( Hooker ex Watson ). This was based on the fact that this plant formed a stem and the leaves were curved with red colouring on the sides.
In his “Agavensystematik fur das IOS-Lexikon (Vorschlag) “ Bernd Ullrich draws attention to the fact that the name Agave gilberti ( Berger ) has priority over the name Agave bakeri
In his work of Gentry you find the name A. gilberti with two “i” i.e. A. gilbertii. In the original description from Berger (1904) in the Monatsschrift f. K. 126 the name is consistently used with only one “i”. The name originates from John Gilbert Baker.
