 This species which is native to the coastal plain from Virginia to Florida 

 and Louisiana and is also found in Cuba has been made by Small the type 

 of the new genus Desmothamnus chiefly distinguished from typical 

 Xolisma by the appendaged filaments and the pair of intra-marginal veins 

 of its leaves, but the absence or presence of teeth or appendages near the 

 apex of the filament does not seem to be a strong morphological character, 

 and in some species these appendages though present become obsolete; 

 it therefore does not seem wise to use this character for generic distinction.

This species which is distributed from Rhode Island to Florida, Tennes- 

 see, Arkansas and eastern Texas has been made by Britton the type of 

 the new genus Neopieris distinguished chiefly by the appendaged stamens 

 a character which seems to be, as I have remarked under the preceding 

 species, not of sufficient importance for generic distinction.
