ROSE AND STANDLEY—MEIBOMIA, SECTION NEPHROMERIA. 215 
20 mm. long, thin, conspicuously reticulate, finely hispidulous; constrictions very 
narrow. * 
Type in the U. 8. National Herbarium, no. 408084, collected by O. F. Cook and 
R. F. Griggs at Cajabon, Alta Verapaz, Guatemala, March 30, 1902 (no. 354). 
The specimen on this sheet is in fruit, but a flowering branch of the same collee- 
_ tion is mounted on sheet no, 408083. The thick leaflets, glabrous and shining on 
the upper surface, distinguish the plant from all the related species, but good 
additional characters are found in the fruit.

Type locality, “Tierras templadas” of Mexico. The species was described 
from plants cultivated from seeds collected by Ghiesbreght. 
We have seen no specimens corresponding to the plates cited and to Hemsley’s 
description of the species. That author describes the loments as subsessile and 
the joints as being one to one and one-half inches in diameter. The leaflets are 
jllustrated as having a lighter, silvery stripe running along the midribs. None 
of our specimens of the section Nephromeria agree with these requirements. 
Meibomia lunata seems to be very closely related and comes from about the 
same region where M. albonitens was probably collected, but that species has 
conspicuously stipitate loments and its leaflets are of the same shade of green 
throughout.

simple racemes or panicles, with uncinate-puberulent branches; flowers on 
slender pedicels 2 or 3 mm. long; bracts deciduous, less than 4 mm. long, lance-
