Suffruticose herbs or shrublets 1.0-1.5 m high; stems coarsely 

 hispidulous, stiffly erect, arising from a woody root-crown from which 

 arise several thick, seemingly fibrous, roots; leaves opposite throughout, 

 mostly 8-12 cm long, 0.6 -2.5 cm wide; petioles 1-10 mm long; blades 

 narrowly lanceolate to elliptic-lanceolate, coarsely hispid above, rather 

 softly silky-pilose beneath, pinnately nervate or weakly 3 -nervate below, 

 the margins serrulate to entire; heads mostly 2-4 in strict terminal cymes, 

 the ultimate peduncles mostly 2-15 cm long; involucres campanulate, 

 6-10 mm long, the bracts subgraduate to subequal, strigose, loosely 

 arranged and often recurved at the apices; ray florets 8-11, the ligules 

 yellow or rarely white to purplish, 7-16 mm long; disk florets 20-60, 

 yellow; achenes 3.5-5.0 mm long, pubescent, the pappus a lacerate 

 crown 0.6-1.0 mm high. 



As noted by McVaugh (1984), this is a highly variable species. 

 Turner (1988) accepted McVaugh's suggestion that the type of Aspilia 

 aggregata is an aberrant individual of W. rosei with nearly sessile heads; 

 since the name concerned predates W. rosei, priority required taking up 

 the former name. Strother (1991) accepted W. rosei as distinct from W. 

 aggregata, the latter known only from the type and differing markedly 

 from W. rosei in having rayless, sessile heads. Turner (1992a,b) 

 subsequently examined the types concerned and agreed with Strother's 

 assessment.
