94 Phytologia (Aug 2004) 86(2) 



Perennial rhizomatous herbs to 1 m high; leaves opposite throughout, 

 6-10 cm long, 3-7 cm wide; petioles markedly winged, 1-2 cm long; 

 blades ovate to deltoid, 3-nervate, roughly hispid, the margins irregularly 

 serrate, lacerate or lobe. 



A very distinct species, presumably closest to W. cordiformis. 

 McVaugh (1984) provides an excellent illustration of the tax on. 



WEDELIA STRIGOSA Hook. & Arn., Bot. Beechy Voy. 435. 1841. 

 Aspilia strigosa (Hook. & Arn.) Benth. ex Hemsl. 



Jal, Col, Mic, and Gue, lower Pacific slopes in tropical deciduous 

 forests, 1-300 m; Jun-Jan. 



Much resembling W. scabra but the vestiture of the leaves without 

 an understory of short uncinate hairs, and the ray florets neuter (vs 

 pistillate). 



Strother (1991) recognized this taxon, correctly noting its relationship 

 to W. acapulcensis (= W. scabra of the present treatment), the latter a 

 widespread, mostly higher montane element in Mexico; W. strigosa is 

 mostly confined to the lower montane slopes from near sea to ca 300 

 m, as noted by Strother. In the vicinity of Acapulco plants seemingly 

 intermediate to W. strigosa and W. scabra occur, possessing uncinate 

 hairs, but these not part of a smaller understory of smaller hairs as occurs 

 in W. scabra. 



WEDELIA TALPANA B. L. Turner, Phytologia 72: 117. 1992. 



Jal, vicinity of El Tuito (Mpio. Talpa), 900-1800 m; Nov-Mar. 



Brittle-stemmed shrubs or shrublets 30-50 cm high; resembling W. 

 rosei but having smaller leaves (mostly 2-3 cm long vs 3-8 cm) and 

 heads sessile or nearlv so.
