Euphorbia penicillata (Millspaugh) R.E. Schultes 
comb. nov. 
Tithymalus pencillatus Millspaugh in Field Mus. 
Publ. Bot. 4 (1925) 95. 
Although the binomial Huphorbia penicillata has been 
used in several enumerations (Herrera: ‘‘Catdlogo alfa- 
bético de los nombres vulgares y cientificos de plantas 
que existen en el Perti’’ (1989) 192; Herrera: ‘‘Sinop- 
sis de la flora del Cuzco’’ 1 (1941) 291), it seems that the 
combination has never properly been made. The specific 
epithet was originally published as pencillatus, an obvious 
typographical error which was corrected in the index of 
the volume.
