- ‘Species are annuals, biennials or rhizomatous perennials and have dimorphic cypselae with the ray fruit lacking a well developed crown of bristles.’
- ‘A typical cypsela is the fruit of a dandelion.’
- ‘The cypsela of the perennial dandelion is classified as an anthocarp.’
- ‘Viable cypselae of any aster or goldenrod from anywhere in the world is most welcomed by the lab.’
