Ver, Oax, Tab, Cps, Yuc, Cam, Qui and Guatemala southwards, 

 widely cultivated in Mexico and elsewhere as a ground cover and often 

 escaping, 0-200 m; all seasons. 



Easily recognized by its prostrate habit and long-trailing stems 

 which root at the nodes; leaves often 3-lobed; relatively large, axillary or 

 terminal, yellow-orange heads; chromosome numbers, n = 20-30 pairs 

 according to Strother (1991); Koyama (1985: Acta Phytotax. Geobot. 

 36:171) reports a count of 2n = 56, or 23 pairs. 



This species was treated as belonging to the genus Sphagneticola 

 by Strother (who used the generic name Complaya, a synonym of 

 Thelechitonia, as noted by Robinson and Cuatrecasas, 1992, the latter 

 proving to be synonymous with Sphageticola, cf. Pruski 1996). 



WEDELIA VEXATA Strother, Syst. Bot. 33: 67. 1991. 



Nay and Jal, Pacific slopes, 0-100 m; Jul-Aug. 



Much-resembling W. scabra but distinguished by its linear-elliptic 

 to lance-elliptic, sessile leaves, with nearly clasping, blades. 



Strother (1991) was clearly vexed by this tax on, hence its name. 

 It has the pistillate ray florets and vestiture of W. scabra, but differs 

 markedly in having more elongate, ellipitcal or lance-elliptic, nearly 

 sessile leaves. Wedelia vexata might also be compared with W. strigosa, 

 the latter possessing neuter ray florets and, in the region where it 

 apporoaches W. vexata (Jal), non-uncinate hairs.
