Agoseris Parviflora, Intermountain Dandelion

Leaves of agoseris parviflora are basal, and plants have no stems; the solitary flowerhead is held on a leafless stalk up to around 10 inches tall when blooming, lengthening to 16 inches or more at the fruiting stage. The stalk may be glabrous but usually has a sparse hair covering, non-glandular; it tends to loose the hairs as the plant matures. Leaves are narrow, almost linear and are lined by small, sharp lobes, usually between five and eight pairs; less often entire. Leaf margins are usually sparsely hairy.

Phyllaries tend to be purplish in the middle, with a darker lengthwise stripe, and green towards the margins, which are ciliate. Phyllary faces may be hairless. The outer phyllaries curve backwards at the tips. The yellow florets number between 30 and 100.
