Aztekia was a Czech journal published from 1978 to 1992. We give below the single issue of 1991 that is devoted to Frič's cactus names. The article is written in Czech language, however there is an english summary (p. 96-97); the lists of plants names (p. 12-77) and bibliographic references (p. 82-96) are standard and easy to read. Finally, using an online translator is sufficient in most case for those who do not read Czech.

NB: Some errors have been corrected in the interpreted file. Those from Frič were preserved for historical reasons.
