In giving this marked species what is believed to be its first descrip- 

 tion the author has duly considered the possibility of retaining the 

 name E. trichotomum long ago applied to the plant by Schultz-Bi- 

 pontinus. However, Schultz working in his usual rapid manner not 

 only failed to give any diagnosis of this E. trichotomum but soon 

 employed in manuscript the same binomial for a wholly different 

 plant. E. trichotomum Sch. Bip. in the latter sense has seen light and 

 received a certain amount of defmition in Mart. Fl. Bras. vi. pt. 2, 

 305 (1876) where established by Baker as a variety of E. Vauihierianum
