Flowers: Inflorescence a bracted, spike-like, terminal cluster, at first dense later elongating and spacing-out some of the numerous, very short-stalked flowers; corollas yellow to orange-yellow, sometimes white, wheel-shaped, 2-5 cm across, 5-lobed, the lobes nearly equal, concave, the tube very short; calyces 5-12 mm long, longer than the flower stalks, hairy, deeply 5-lobed, the lobes lanceolate; stamens 5, the 3 upper filaments densely, long, white-hairy, the 2 lower filaments smooth or nearly so.
