Morphology The rosettes are 1 to 1.5 cm high, 7 to 10 mm thick, with around 50 to 100 papillose and bluish leaves. The floral stems are 3 to 7 cm tall, and around 1 to 1.5 mm thick, textured smoothly, light green. The stems cluster around the base in flower. The bracts are spreading or somewhat ascending, oblong, narrowly rounded at the apex, sub-truncate at the base and contracted to a narrow point of attachment. The dimensions of the bracts are 4 to 6 mm long, 1 to 1.5 mm wide, and .75 to 1 mm thick. By the time of flowering, many of the bracts may have already withered or fallen off. The inflorescence has roughly 2 to 3 flowers, with pedicels 1 to 2 mm long, and around 1 mm thick, and papillose. The calyx is also papillose, with nearly-equal segments, that are ascending in bud and spreading in flower. The corolla is 8 to 9 mm wide, greenish-white and somewhat marked with pink. The petals are reflexed, triangular-lanceolate, acute, and 3.5 to 4 mm long, 1.25 to 1.5 mm wide. The filaments are whitish, ascending and the anthers are red, ovoid. Plants have a chromosome number of n=18. Flowering is from September to October.
