Notes. <i>Artabotrys aurantiacus</i> is distinguished by its sparsely pubescent to glabrous branches and leaf blades (upper and lower sides), with leaves that are relatively small but wide (less than 10 cm and up to 6 cm wide) and oblong to elliptic in shape with a cuneate to rounded base. The flowers have narrowly elliptic petals and the monocarps are smooth, ellipsoid with a rounded apex.
