Leaves all cauline, sessile; leaf sheath 2--4 mm, with a line of dense, multicellular villous hairs; proximal leaf blades elliptic, 2--4 × 0.7--1.3 cm, glabrous, apex acute; distal leaf blades ovate, ca. 10 mm. Flowers 1--3, in fascicles in leaf axils; pedicel ca. 3 cm, with transparent, membranous leaf sheath near base, jointed at middle, mostly straight in fruit, sometimes slightly curved. Sepals narrowly ovate, ca. 3.5 mm. Petals blue or pink, orbicular. Fertile stamens 3; filaments sparsely red torulose villous; staminodes 3; antherodes sagittate.
