STAKDLEY TREES AND SHRUBS OF MEXICO. 1247 



Sinaloa and Durango to Chiapas, Mexico, Veracruz, and Yucatttn. Central 

 America. 



Slirub or tree, 1.5 to 12 meters liigli ; leaves short-petiolate, narrowly lanceo- 

 late to broadly ovate, 6 to 20 cm. long, obtuse to attenuate, acute to rounded 

 at base, finely or coarsely crenate, scabrous or scaberulous above, usually 

 tomentose beneath ; heads very numerous, long-pedunculate, in fruit 1 to 2 cm. 

 thick, the bracts commonly reniforra or broadly ovate-cordate; flowers yel- 

 lowish, turning red. " Nacare," " topozana " (Sinaloa); " tabaquillo " (Mi- 

 choacan) ; " hierba de la mula " (Durango); "salvia," " rosa de Castilla " ; 

 '"caragra" (Costa Rica) ; " seca-leche " (Guatemala, Honduras) ; " juanislama 

 de monte" (Nicaragua) ; " oreganillo," " oregano montes " (El Salvador). 



In Durango the plant is used as a remedy for colic. The numerous speci- 

 mens at hand show considerable variation, especially in pubescence and size 

 of lieads, but there do not appear to be any well-marked characters by which 

 it is possible to distinguish the proposed segregates.

 " tamayagua," "oreganillo," "salvia" (El Salvador). 



Lippia yucatana was described from Yucatan. The writer has seen no 

 Yucatan specimens of L. myriocepliala, and it may therefore be that L. yuca- 

 tana is a distinct species, or possibly a synonym of L. umbellata.
