The outer bracts of the Syncarpha canescens flowerheads in picture are dark pink purple, the inner rows of the involucres paler pink on both surfaces. The inner bract surfaces are concave and the bracts curve in to their tips. The bract tips appear to end in tiny mucro-like extensions.
Spiders are not commonly listed as pollinators. Many webs in the world are spun privately, however, aimed at surprise. Captured insects may still deliver for a flower as they wriggle in the quest for freedom. And there are so many arachnoids on earth that the diets of some may also surprise.
The flowerhead discs comprising numerous tiny, five-lobed florets are dark, nearly black. Only some yellow anthers are visible from open florets, as well as maybe some whitish styles, but not simultaneously from the same bisexual florets.
The dark-rimmed leaves, simple and stalkless, overlap on the erect stems, adhering to them (Curtis-Scott, et al, 2020; Manning, 2007; iNaturalist).
