Pappus, head size, and branching pattern vary in Lasthenia coronaria. Two types of pappi are often found within a head and sometimes in different individuals of a population. The most distinctive feature of this species is its glandular herbage, which produces a characteristic sweet scent not present in any other lasthenia.
