Formerly classified and still listed in some references as, Wedelia trilobata

Comments:

Wedelia trilobata (L.) Hitchc. is not a true Wedelia. This species is now called Sphagneticola trilobata (L.) Pruski.

Sphagneticola trilobata differs from true Wedelia (typified by a West Indian shrub):

  1. by being a stoloniferous herb rooting at the nodes with stems elongating sympodially thereby laterally displacing the terminal capitula
  2. by abaxially glandular ray limbs
  3. by black ovate anther appendages
  4. by tuberculate cypselae without well-developed carpopodia and without elaiosomes or pappus awns

"Wollastonia biflora" seems best retained as is.
