Specimens examined: 
Mexico: State of Yucatan, vicinity of Izamal, coll. of 1895, Dr. 
Geo. F. Gaumer, 713, TYPE, and 506 (both in Mo. Bot. Gard. 
Herb.); road to Progresso north of Merida, 7 April, 1865, 
Schott, 262 (Mo. Bot. Gard. Herb.), distributed as “E. 
aculeata." 
Co-types of the above species may be looked for in herbaria 
under R. xalapensis under which name Dr. Gaumer's material 
cited above was distributed. From this species, however, В. 
truncata differs in the more obovate outline and the less conspic- 
uous veins of the leaf, the somewhat longer and more slender 
corolla-tube, and in the smaller truncate calyx.
