Diagnostic characters

Inulanthera schistostephioides is readily distinguished by its pinnatisect, strongly discolourous leaves with the upper surface thinly cobwebbed and dark green in colour and the lower surface densely woolly and yellowish-beige in colour (Fig. 12B). The lobes are distinctly mucronulate.
