Just need to share these two observations - and asking at the same time for comment - I’m not an expert and may be giving incorrect advice
See this from Parasitic Plant Connection - Cytinaceae
Notice there are flowers with bright red perianths whereas others are darker. This species is considered by some to be conspecific with C. capensis (hence C. sanguineus a synonym of C. capensis ).
Not sure I can help as don’t think I have ever seen Cytinus, not even the European ones. Interesting that they are in the Malvales.
Thanks Mike not common. Just found the old links interesting
Sad that we lost Pricilla. She would have loved to follow these up.
