The pair of bracts below the inflorescence resemble stem leaves, nearly ovate, sessile or with inconspicuous short stalks. Umbel inflorescences densely arranged to form a 2-4cm long spike, with each umbel inflorescence subtended by bracts; bracts broadly heart-shaped, usually about 7mm long, 11mm wide, with a long acute tip of 1-2mm at the apex, radial veins, sparsely stiff hairs along the veins below the middle on the outer surface, hairless on the inner surface, ciliate margins, membranous, pale purple.
