Much-resembling W. rosei but the stems mostly short and ascending 

 to procumbent ( 1 0-25 cm high vs 1 00- 1 50 cm), the leaves coarsely hispid 

 beneath (vs softly silky pilose), the heads single at the apices of branches 

 (vs 2-4 on short peduncles (mostly 1-2 cm long vs mostly 2-8 cm). 



The specific name was originally spelled, in error, W. gonzalezorum, 

 as noted by Strother (1991).

Much-resembling W. mexicana but the leaves longer, the blades 

 mostly elliptic to oblanceolate, stems ligneous and branched so as to 

 form low mats; those of W. mexicana, while decumbent, appear to arise 

 from a well-defined, woody, corm-like, caudex or rootstock; in addition, 

 the rays of W. mexicana are yellow and the heads are smaller.
