peduncles 2-8 cm long; involucres 6-10 mm high, 2-3 seriate, the bracts 

 subequal or the outer somewhat longer. Ray florets 8-13, the ligules 5- 

 10 mm long. Disk florets 30-50, the corollas yellow, 4.5-5.0 mm long. 

 Achenes unwinged, the pappus a crown of scales ca 0.5 mm high and 1 

 or 2 lateral bristles, 1.0-1.5 mm long. 



Much-resembling the more eastern W. hispida but the leaves evenly 

 serrate, pubescent principally along the veins beneath, the heads borne 

 2-3 in lax corymbs. It might also be mistaken for W. strigosa, but the 

 latter is a shrub or shrublet confined to the Pacific slopes from 0-300 m. 



WEDELIA CORDIFORMIS McVaugh, Contr. Univ. Michigan Herb. 

 9:460. 1972. 



Known only from the type (Jal, ca 12 km wnw Tototlan towards 

 Zapotlanejo), poorly drained meadows, ca 1800 m; Aug. 



Perennial herbs, growing in clumps to 1 m high; stems stiffly erect, 

 very coarsely hispid, 4-5 mm thick at mid-stem; leaves opposite, 6-10 

 cm long, 2-4 cm wide, sessile or nearly so; blades lance-ovate, somewhat 

 clasping, pinnately-veined, roughly hispid, the margins serrulate; heads 

 radiate, 4-5 cm across the extended rays, the ultimate peduncles 5-15 cm 

 long; involucres 13-17 mm high, the bracts subequal; ray florets 13-18, 

 the ligules 15-20 mm long; achenes pubescent, the pappus of a single 

 awn ca 1.5 high and a crown of scales ca 0.7 mm high. 



A very distinct species, not easily confused with another. McVaugh 

 (1984) provided an excellent illustration of the taxon. 



WEDELIA CRONQUISTII B. L. Turner, Phytologia 65: 350. 1988. 



Known only from Jal (ca 23 km mi n of Guadalajara), oak woodlands, 

 1500-1600 m; Nov. 



Suffruticose perennial herbs to 1 m high; leaves opposite throughout, 

 3-6 cm long, 2-6 mm wide; petioles 0-1 mm long; blades linear to linear-
