 gravelly plain near Guadalajara, Oct. 14, 1903, Pringle, no. 11,848.

 glabra, foliis orbiculatis palmatis non peltatis fere ad petiolam pro- 

 funde 7-8-lobatis, supra viridibus subtus pallidis venis albis reticula-

 apicem late et abrupte rhombeo-dilatatis apice setaceo-mucronatis,

 orum superiorum leviter sinuatis nee lobatis nee rhombeo-dilatatis, 

 petiolis limbo brevioribus vel eum subaequantibus glaucis, racemis

 915 m., July 29, 1907, Pringle, no. 13,938. Intermediate between M.
