Recently withered Senecio sarcoides flowerheads still have bright green to yellow-green involucres and pedicels. The brown, dry tissue visible above some of the involucres may include a little of the earlier yellow ray floret remains among the transforming disc florets.
The bracts on the flower stalks in picture seem to have dropped off already. These bracts are narrow, alternate and 1 cm long. The white bristles of the pappuses are either conspicuous, still developing or already departed in the stages of flowerheads represented in picture.
The inflorescence of a S. sarcoides plant is about as long as its leaf. The photo was taken at Naries, north of the Spektakelberg in Namaqualand (Le Roux, et al, 2005; Manning and Goldblatt, 1996; iNaturalist).
