In April 2007 in Succulenta, the magazine of the Belgian and Dutch Succulent Society, there appeared an article by Alsemgeest,van Roosbroeck and Walderveen describing the four major forms of agave victoriae-reginae, based on studies of these plants whilst travelling through their natural habitat.
The full article, translated into English, is to be found here : http://www.agaves.nl/Articles/E_victoriae%20reginae.htm
Ag. victoriae-reginae f. compacta. f. viridis ( Breitung 1968 ) f. fernandi-regis ( Berger 1915 ; since 2011 newly renamed as nickelsiae )
 
In 2011 there was a further revision by Gonzales Elizondo et al. published in Acta Mexicana. The new revision suggests the following groupings:
1. victoriae reginae ssp. victoriae-reginae (western Nuevo León and eastern extreme of Coahuila
2. victoriae reginae ssp. swobodae (southern Coahuila and northeastern Durango)
3. nickelsiae (microendemic to southeastern Coahuila) ; replaces fernandi-regis
4. pintilla (the most westernly distributed species in the group, restricted to southeastern Durango).
