Perennial, with stout us. much-branched stems which are prostrate below (often ± buried) then ascending to suberect, 7·5-15 cm. long. Basal lvs ∞, crowded; lamina thick to rather thin, 10-20 × 5-7-9 mm., spathulate or linear-spathulate, obtuse, narrowed to slender petiole ═ or > lamina, nerves not evident. Exposed lvs ± fleshy. Cauline lvs similar, on shorter petioles, close together or distant. Fls terminal, solitary, or in 2-5-fld cymes at tips of branches. Calyx broad, often c. ? corolla-length, cut nearly 3/4 way into linear or linear-ligulate obtuse or subacute lobes recurved at tips; sinuses us. narrow and acute, or one or more broad and rounded. Corolla often up to 20 mm. diam., white, broadly campanulate to subrotate, cut rather > 1/2 way into oblong, obtuse lobes.
