Flowers in extra-axillary or axillary, few-flowered fascicles heads or racemes, much shorter than the leaves, sometimes solitary. Bracts persistent. Wing-sepals oval or obliquely elliptical, pubescent, with a principal median often broadly herbaceous nerve, and faint looping and divergent lateral ones. Lateral petals obovate to ovate.
