(1904). Not seen, but from description and aru easily distin- 
guished from N. hirsuta by the elliptic-ovate obtuse or rounded 
leaves. Based on Gauwmer, 977, from Izamal, Yucatan, described 
as a “shrub, 20 feet high, * with “flowers white, very aromatic.” 
Schott, 755 (Brit. Mus.), from near Hacienda Chued, Yucatan, is 
referred with some doubt to 5 species.
