Family: Cactaceae (Cactus Family) 

Scientific name:  Mammillaria heyderi ssp gaumerisubsp. gaumeri (Britton & Rose) D. R. Hunt 1997 
Published in : Mammillaria Postscripts 6:10. 1997

Conservation status: Listed in CITES appendix 2.

Origin:  Yucatan, Mexico. Almost Endemic of Savana Chichulu and perhaps in the nearest forests of Yucatán and Quintana Roo (under different climate)  Altitude just above sea level to 8-25 m.
Habitat: This is a rare species that would delight any naturalist, it grows in full sun or under shrub canopy half-hidden in the dunes sand  of the beachfront land in the amazing transition zone between the mangroves - where saltwater occasionally floods in the almost-flat land - and the scrubby, spiny, arid-land with succulent plants typical of inland northern Yucatan.


 

 


Cultivation: This is an easy to grow species, don't requires any special treatment, but need as much light as possible without burning the plant to encourage the heaviest spine formation. Needs a very good drainage with regular water in summer, dry in winter. Avoid any frost.

Propagation: Seeds, offsets (Allow cut surface to callous over before planting)
