Taxon Name: Neolloydia conoidea (DC.) Britton & Rose
Synonym(s):
• Mammillaria conoidea DC.
Taxonomic Source(s):
Hunt, D., Taylor, N. and Charles, G. (compilers and editors). 2006. The New Cactus Lexicon. dh Books,
Milborne Port, UK.
Taxonomic Notes:
Neolloydia matehualensis is most likely conspecific with N. conoidea Backeb.; plants with the same
characteristics of N. matehualensis appear in M. conoidea subpopulations (H. Hernández., W.A. Fitz
Maurice and B. Fitz Maurice pers. comm. 2009). However, for the purposes of this assessment they are
both kept as good species and assessed separately.
Assessment Information
Red List Category & Criteria:
Least Concern ver 3.1
Year Published:
2013
Date Assessed:
November 17, 2009
Justification:
Neolloydia conoidea is listed as Least Concern due to widespread and abundant populations, and
because it is not declining at a rate sufficient to qualify for a threatened category.
Geographic Range
Range Description:
This species is widely distributed in the Mexican states of Aguascalientes, Coahuila, Durango,
Guanajuato, Hidalgo, Nuevo León, Querétaro, San Luis Potosí, Tamaulipas and Zacatecas, and in Texas in
the USA (Hernández et al. 2004). It grows at elevations of 400 to 1,550 m asl (Martínez-Avalos and
Jurado 2005).
Country Occurrence:
Native: Mexico (Aguascalientes, Coahuila, Durango, Guanajuato, Hidalgo, Nuevo León, Querétaro, San
Luis Potosí, Tamaulipas, Zacatecas); United States (Texas)

Population
The species is very abundant throughout its distribution.
Current Population Trend: Stable
Habitat and Ecology (see Appendix for additional information)
The species tend to grow in xerophyllous scrub, on limestone and rocky slopes (Goettsch and Hernández
2006).
Systems: Terrestrial
Use and Trade (see Appendix for additional information)
This cactus is rarely sold as an ornamental in the international trade.
Threats (see Appendix for additional information)
Grazing of livestock poses a threat to some subpopulations due to trampling.
Conservation Actions (see Appendix for additional information)
More research is need on harvest levels and trade in this species.
