Discussion

The coastal habitats, low habit, and broad, fleshy-thick leaves of var. sedoides are characteristic. Intermediates with var. vernonioides have been collected at every locality where var. sedoides occurs, and some identifications will have to be made arbitrarily. H. M. Hall (1928) treated var. sedoides within var. vernonioides.
