 puberulis; bracteolis sepaloideis lineari-oblongis obtusis 4-5 mm.

 Mexico, 25 August, 1899, E. W. Nelson, no. 6099 (type, in hb. Gray); 

 also earlier at the same station, alt. 2285 m., Townsend & Barber, no. 

 31. This species appears to be most nearly related to G. Drummondi 

 Benth., which, however, has narrower more attenuate leaves and a sub- 

 orbicular obtuse capsule scarcely half the length of the lance-linear 

 calyx-segments. 



In a recent attempt to revise and label in accordance with the 

 Vienna Rules of Nomenclature the material of the genus Bacopa in 

 the Gray Herbarium the writer has found it necessary to employ sev- 

 eral apparently new combinations, which it may be well to record here, 

 as follows :
