On basaltic cliffs. Plants low, spreading, usually the stems consisting of 2-4 joints, flowers yellow to distinctly salmon pink, apparently on the same plant, but possibly on different plants growing en masse, stem joints obovate, no larger than those collected, easily broken apart, spines (as felt by rolling between the fingers) definitely flattened, as seen in cross section near the base, about 1.5 times greater in one dimension than in the other, minutely barbellate at the tip, but the barbels too small to be felt. Phenology: Flowers & Fruits.
