Taxonomy

C.C. Berg in his publication in Blumea classified ''F. deltoidea'' into two sub species based on difference of the leaf shape, subsp. ''deltoidea'' and subsp. ''motleyana'' (Miq.) C.C. Berg''.'' ''F. deltoidea'' subsp. ''deltoidea'' has board leaf shape variation from obtriangular to linear-oblanceolate, include apex and based on lamina variation in the common deltoid shape with furcate midrib. ''F. deltoidea'' subsp. ''motleyana'' has oblong to lanceolate lamina shape with pinnately vein. The first subspecies with deltoid leaf shape is a common taxa to be used as medicinal plant. Lee et al. (2016) success to conduct molecular analysis with cpDNA and nSSR marker system for ''F. deltoidea'' from Peninsular Malaysia and the result support taxonomy classification based on morphological traits.
