12. Eupatorium galeottii Robinson, Contr. Gray Herb. n. ser. 68: 17. 1923. 



Veracruz; type collected on the Cordillera at an altitude of about 915 meters. 

 In habit and foliage close to the preceding, but said to be less lignescent; 

 phyllaries all pointed. 



13. Eupatorium oaxacanum Klatt, Abh. Naturf. Ges. Halle 15: 324. 1882.

,\ smooth, viscid and somewhat vernicose shrub; branches and foliage rather 

 willow-like; leaves opposite, short-petioled, lanceolate, pointed at each end,

 heads about 10-flowered, in trichotomous fiattish corymbs; phyllaries lanceolate
