Cauline leaves (ascending); sessile; blade lanceolate to oblong, 1.8-4.5(-6) cm × 5-16(-24) mm, (base amplexicaul to strongly auriculate), margins entire. Racemes lax, slightly elongated in fruit, (flower buds oblong-linear). Fruiting pedicels horizontal to divaricate, usually straight, rarely slightly incurved, slender, (2.5-)3-5.5(-6.5) mm, slightly flattened at base.
