C. pauciflora is an annual herb producing a slender, crooked, branching stem coated with hairs, growing up to 50 centimeters (20 inches) tall. The leaves are linear in shape and up to 5 centimeters (2 inches) long. The inflorescence bears bracts studded with large resin glands and small clusters of flower heads. The hairy, glandular flower head has a center of a few disc florets and one or two white or red triple-lobed ray florets. Each ray floret has three lobes at the tip, the middle lobe being shortest. The fruit is an achene; those developing from the disc florets have a pappus of scales.[3]

Taxonomy

The specific epithet pauciflora, referring the Latin term for 'few flowered'.[4]

gollark: There was that thing where some scientists put... flies, I think it was, in some environment where they couldn't have much of a population. They did not evolve to have fewer young or something. They evolved to cannibalize each other's young.
gollark: Evolution doesn't really select for the good of the species either, just the propagation of your genes.
gollark: Congratulations!
gollark: Modern high-core-count Intel CPUs will *happily* use hundreds of watts if the configuration allows it.
gollark: Daylight saving time: because if someone is unhappy with how their work hours line up with sunlight or something, the obvious solution is to meddle with the fabric of time itself and cause untold hundreds of issues in computer programs everywhere.
