Simple, not offsetting, at first spherical, then becoming oblong, however hardly showing above soil level, main part of the plant hidden in the soil. Watery juice! Size to 6 cm high and 4.4 cm wide. Apex sunken and filled with short felt-like hair. Tubercles almost square at the base, at the top completely pressed flat, exactly looking and ordered like Solisia pectinata. Consequently the plants are almost hardly distinguishable. However at the top of the areole a short tuft of wool appears, if they are still young. The flowers emerge from the areole at the upper edge of the tubercle, almost somewhat inwards of it. Axil bare. Areoles narrow-oblong, covered by crest-like, flat spreading, glass-white, small spines, ca. 1.25 mm long, at the base somewhat greyish-yellow, so that the crest-like spination shows a dark stroke in the areole. Flowers to 1-3 from the latest areoles in the apex, emerging from a tuft of felt-like wool at the upper edge of the areole, ca. 2 cm long; short greenish tube, bare; outer perianth segments below, dark reddish-brown, above whitish-pink with rich reddish-brown mid-stripe, inner perianth segments all slender, pointed, pale white-pink with rich reddish-brown mid-stripe. Fruit small, dark green.
Locality: Palmillas, Tamaulipas, México.
