The flower head of Rhagadiolus stellatus closely resembles a regular flower but is formed from a few, 5 to 10, yellow florets emerging from a tubular involucre. It is unusual for a member of the Asteraceae; it does not have vertical flower stems arising from the centre of a flattened rosette of leaves, as most members of the daisy/dandelion family but has long thin stems which radiate and scramble through the surrounding vegetation. It also has unusual fruits, which form a characteristic green star; this gives the species name stellatus. It is one of only two recognised species of the genus Rhagadiolis and the only one growing on Skopelos.
