The bracts surrounding the base of the flower are overlapping in 4 to 6 layers; bracts are lance to triangular, green often with a purplish tip, variously hairy and sometimes glandular. Flower stalks are from less than ¼ inch up to nearly 2 inches long, variously hairy and may be glandular.

Leaves and stems: Leaf attachment: alternate Leaf type: simple
Leaves are alternate, about 1 inch long and ¼ inch wide, toothless, stalkless, pointed or blunt at the tip, oblong or widest at the tip end and tapering at the base, and often twisted or wavy. Surfaces are variously hairy, from sparse to densely covered in long white hairs, and the color is correspondingly green to gray-green.
