Xerophyte

Note

All of the Ariocarpus seedlings are spiny and quite different from adult specimens, though the spines are feather-like.

Tubercles

Leaf-like, divergent, erect, basally compressed, usually becoming attenuate at the apices, convex or nearly flattened adaxially and often with shallow adaxial undulations or wrinkling, not fissured, 1,5-4 cm long, 1-3,5 cm wide, nearly as wide as long.

Flowers

Diurnal 4-5cm in diameter, 2-4,2 cm long, white to pink , occasionally with reddish midribs.

Forma Aurea

The yellow schizochromic form (Ariocarpus hybrid retusus f. aureaSN|2079]]SN|26100]]) has bright golden yellow stems due to the absence (or reduced production) of chlorophyll pigments

Blooming Season

Autumn.

Stem

Solitary, pale to golden yellow or orangish, flattened, globose, rounded on top, 3-12 cm high, 10-25 cm in diameter.

Areoles

At the tips of the tubercles, rounded, 1-5 mm in diameter often only on younger specimens.
