Synonyms[1]

These are annual herbs with coatings of hairs and globose glandular structures. The alternately arranged leaves have wavy or serrated blades on petioles. The inflorescence is a panicle[2] which can be terminal or axillary.[3] Some inflorescences have few flower heads, and some heads are solitary. The hemispherical head has up to 6 layers of phyllaries. It contains many purple florets which are tubular and expanded at the mouth into five pointed lobes and bear a long, branching style. The fruit is a compressed achene, usually with ten ribs, but sometimes with five. Some achenes have a pappus of up to 10 fragile bristles.[2] The pollen of plants in the genus has a unique "6-porate echinolophate" morphology.[3]
