Taxonomic Comments
Kartesz (1994) recognized Trifolium polyodon as distinct from Trifolium variegatum but did not recognize Trifolium appendiculatum, which is also treated as a distinct species by Foster and Vincent (2018). In addition, varieties are not recognized; Trifolium variegatum var. rostratum and Trifolium variegatum var. major, combined, roughly equate to T. appendiculatum. Trifolium variegatum var. parunuweapensis is considered a synonym of Trifolium mucronatum ssp. lacerum (Foster and Vincent 2018).
