Monoptilon bellidiforme is very similar to
monoptilon bellioides, the only other member of this genus, which inhabits the same areas; distinguishing features include the larger flowers (relative to the leaves), the yellow green stems (rather than reddish), and the pappus, which has a single, plumose bristle, compared with up to 15, non plume-tipped bristles.
Leaves are bright green, sparsely covered on both surfaces by bristly white hairs, as are the stems, which are ascending to prostrate, and short. Flowerheads are sessile, with 10 to 14 phyllaries, 12 to 21 white ray florets and 28 to 40 yellow disc florets. Phyllaries are narrow, green and often red at the tips.
