Strother (1991) called attention to some of the plants which 

 comprise this taxon, noting that these might be deserving of specific 

 recognition. Additional collections from the same region, in my opinion, 

 has confirmed this observation.

Wedelia acapulcensis var. tehuantepecana (B. L. Turner) Strother 



e Oax, s Ver, and Cps, tropical deciduous forests, 50-700 m; Jul- 

 Nov. 



Much-branched erect or procumbent shrubs or shrublets 0.5-1.5 m 

 high, leaves opposite, 4-10 cm long, 1.5-4.0 cm wide; petioles 0.5-1.5 

 cm long, the upper portion winged; blades ovate to subdeltoid, 3-nervate, 

 coarsely hispid, uncinate hairs absent, the margins serrulate to coarsely 

 and irregularly dentate; heads radiate, mostly 1-3 in terminal cymes, 

 the ultimate peduncles mostly 2-8 cm long; involucres 10-12 mm high, 

 narrowly campanulate, 2-3 seriate, the bracts subequal, the outer series 

 greener and somewhat longer than the inner; ray florets 5-11, sterile 

 (rarely fertile), the ligules 5-10 mm long; achenes, those of the ray, with 

 a raised crown bounded by 3 bristles, those of the disk 5-6 mm long 

 with a raised crown and usually 2 or 3 bristles 3-6 mm long, the margins 

 markedly winged at maturity; n = ca 26 pairs. 



Closely related to W. scabra but lacking the fine, uncinate, indument 

 on the under-surface of the leaves of that species and possessing mostly 

 larger heads with longer achenes with raised crowns having bristles 3-6 

 mm long.
