The young branches are quadrangular and tomentose, bearing ovate or ovate-lanceolate membranaceous leaves 9 25 cm long by 4 10 cm wide, initially thickly tomentose but later glabrescent above, but remaining tomentose below. The yellowish white inflorescences are 15 40 cm long, and as wide at the base, with leafy-bracted primary and secondary branches perpendicular to each other. The flowers are borne as compact heads, approximately 1 cm in diameter, each with around 20 flowers, the corollas 3 mm long.[2]
