Flowers:
Heads with strap-shaped flowers, 20-60 in a flat- or round-topped inflorescence; involucres 5-8 mm tall, cylindric to top-shaped; involucral bracts glabrous or woolly, the outer ones about 8, linear, up to 1/2 as long as the 8-16 inner ones, these woolly and often glandular-bristly with black hairs as well, glabrous within, lanceolate, abruptly sharp-pointed, becoming spongy-thickened on the back; receptacle glabrous; ray flowers yellow, 7.5-12 mm long.
