Inflorescence a long, slender, terminal, spike-like raceme of 10 to 50 small, short-stalked flowers, the racemes 10-40 cm long, the axis glandular and with long spreading hairs; corollas yellow, saucer-shaped, the petals 5, oblong, 2-4 mm long; calyces 5-lobed, the lobes broadly lanceolate, spreading then converging after flowering and forming a beak on the fruit, the hypanthium conic, grooved, hooked-prickly; ovaries superior; stamens 5 to 15.
