Euchiton sphaericus
Euchiton gymnocephalus
In California and Hawaii, plants of Euchiton sphaericus have been identified as Gnaphalium japonicum; annual duration, slender taproots, non-clasping leaf bases, and single bisexual florets establish the correct identity of E. sphaericus. It “varies enormously in length, position and degree of branching, and the branches may be either vegetative or flower-bearing” (D. G. Drury 1972).
