Origin: Yucatan, Mexico. Almost Endemic of Savana Chichulu

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.
