Cauline leaves like rosette leaves, or slightly broader. Raceme 3-12-flowered, very dense at first, to 8 cm in fruit; lowermost bract like upper leaf but shortly stalked, upper much smaller, divided to often entire. Pedicel 3-4 mm in flower, 9-15 mm in fruit, erect. Sepals 2-3 × ca. 2 mm, deeply lacerate-dentate. Corolla milky white to pale yellow. Outer petals broadly navicular, subacute, without crest; upper petal 13-16 mm; spur cylindric, 7-8 mm; nectary ca. 1/2 as long as spur; lower petal 8-9 mm, broadly saccate along whole length, except for very base where there is often a small gibbosity; inner petals 6-8 mm. Stigma square; marginal simple papillae: median 2 distinct, lateral diffuse; geminate papillae lateral and in basal corners. Capsule obovoid to oblong, 10-13 × ca. 3 mm, 5-15-seeded.
