Senecio is derived from the Greek "old man", referring to the pappus of abundent white bristles or hairs. Senecios are ubiquitous "damn yellow composites" of moderate to high elevations. The flowers usually are composed of yellow ray and disk flowers and have a somewhat ragged appearance compared to the more regular Heliantheae. Groundsel Tribe members have a pappus of white, silky hairs. More cryptic characters include style branch appendages which are absent or papillate.
