Ariocarpus Lloydii

______________________________________________________________________

The tubercles of Ariocarpus fissuratus are covered with fissures, hence the name. The plant looks closely like a rock (or some might say to a sun dried cow pie). It is quite difficult to locate in the wild.
 

Cultural Practices:
The Ariocarpus are rare slow growing cacti, a 6 inches in diameter mature specimen might be 20 years old. For many years the large mature specimens were collected in the wild, practice that has been severely limited by the new regulations, either in Mexico or in international trade. They are not adapted as house plants as they need a lot of sun and careful watering. The large taproot needs enough room to grow, which complicates the good drainage requirement, since the deeper the pot, the slower it drains.
The center growing part is sensitive to mealybugs attacks. Since this part is woolly, mealy bugs can be difficult to notice. The plant should be treated as soon as mealybugs are noticed.

Blooming Habits:
The Ariocarpus fissuratus has large, 1.5 inches in diameter (4 cm), pale to deep pink satin flowers in mid summer, followed by fruit buried in the wool.

Is found further south in regions of higher rainfall. The tubercles have only a slight furrow. Since this variety has a more stable water supply , it does not need the wrinkles which allow it close relatives to expand and contract in relation to water content.

Contains: hordenine, N-methyltyramine
