Herbs usually sparsely strig­illose, sometimes glandular puberulent. Leaves 0.6–3.5 × 0.1–0.6 cm, fascicles of small leaves to 1.5 cm usually present in axils; blade usually narrowly lanceolate to lanceolate or oblanceolate, rarely linear, base attenuate, margins subentire or serrulate, usually crinkled-undulate or undulate. Flowers: buds with free tips 1–6 mm; floral-tube 17–45 mm; sepals 11–27 mm; petals 10–30 mm; filaments 6–12 mm, anthers 5–9 mm; style 25–60 mm. 2n = 14, 28.


Phenology: Flowering Mar–Sep.
