Species 3 (3 species, including 1 hybrid, in the flora).
Leaves of Borrichia species are usually heteroblastic: leaves on primary stems are usually ± petiolate (sometimes with spine-tipped teeth on margins of petioles or near bases of blades) and larger and relatively broader than the usually sessile leaves on secondary stems.
|1||Leaves (at least mid cauline): margins entire or dentate to serrate (teeth remote, mostly toward apices), faces glabrous or sericeous; phyllaries (chartaceous in fruiting heads): apices acute, rounded, or obtuse; paleae: apices obtuse to acute||Borrichia arborescens|
|1||Leaves (at least mid cauline): margins usually dentate to serrate, rarely entire, faces usually villous (longer hairs) and/or sericeous (shorter hairs) to glabrate, rarely glabrous; phyllaries: apices cuspidate or spine-tipped; paleae: apices cuspidate or spine-tipped||> 2|
|2||Mid-cauline leaves (petioles or blade bases with spine-tipped teeth): margins dentate to serrate (usually only proximal 1/3–1/2, rarely most, of each margin); phyllaries (often reflexed, swollen in fruit): apices spine-tipped; paleae: apices spine-tipped||Borrichia frutescens|
|2||Mid-cauline leaves: margins dentate or serrate (at least mid portions, often undulate as well); phyllaries: apices cuspidate; paleae: apices cuspidate||Borrichia ×cubana|
