 rigid, oblong-ovate to subrhomboid, broadest conspicuously above 

 the middle, the principal ones 3-5 cm. long by 1.1-1.9 cm. wide, 

 acute, entire and subrevolute, gradually narrowed to an obtuse

 below; veins not prominent, sessile or on petioles 1-2 mm. long; 

 inflorescence of several short few-headed cymes in the axils of the 

 upper leaves, forming a compact leafy panicle; bracteal leaves 

 barely exceeding the heads, ovate to ovate-lanceolate; heads 

 crowded in clusters of 2-7, or sometimes single, sessile, not at all
