Ariocarpus Furfuraceus var. Rostratus Cactus Seeds
Rostratus refers to plants with a more tapered apex to the tubercle. Ariocarpus furfuraceus differs from the standard Ariocarpus retusus only for its equilaterally triangular tubercles, all the other characteristics clearly show that they are conspecific. The variety “furfuraceus” is distingushable for the dark green-brown-grey equilaterally triangular shaped tubercles with abundant white wool at the apex. The tubercles are also usually more obese, pointed and smooth, with areoles on the tip.
