424 STANDLEY: CHENOPODIACEAE 
ATRIPLEX GLOMERATA S. Wats.; Standley, N. Amer. FI. 21: 54. 
1916 
Founded upon Palmer’s No. 1156, collected at Parras, Coahuila, 
in 1880. The type specimen, in the United-States National 
Herbarium, bears the previously unpublished name cited above. 
The plant is related to the Mexican A. muricata Humb. & Bonpl., 
but differs in having unappendaged bracts. Two additional col- 
lections belong here: 
Mexico: Coahuila, Rose 3075; en Vista, Gregg 349. 
ArripLex Davipsonm Standley, N. Amer. Fl. 21: 57. 1916 
This name is proposed for a plant closely related to A. pacifica 
A. Nels. (A. microcarpa [Benth.] D. Dietr.) and A. Coulteri (Moq.) 
D. Dietr., but distinguished from both by its dentate leaf blades. 
In the form of its staminate inflorescence it is intermediate between 
those two species. The following collections have been examined: 
CALIFORNIA: Balboa, Davidson 2951 (type); Long Beach, 
W. F. Parish; Los Angeles, Braunton 680; in eas Nevin; Colton, 
Parry 287. 
ATRIPLEX SONORAE Standley, N. Amer. Fl. 21: 62. 1916 
An ally of the Mexican A. Barclayana (Benth.) D. Dietr., but 
separated by the very different fruiting bracts, these being united 
only to the middle, their margins green and deeply laciniate, and 
their sides sharply muricate. The following collections belong 
here: 
Sonora: Empalme, Rose, Standley, & Russell 12631 (type); 
Guaymas, Palmer 671,672, 673, 674, 677, 690. SINALOA: Altata, 
November, 1899, Brandegee.

Atriplex curvidens Brandeg. Proc. Calif. Acad. II. 2: 201. 1889. 
The type of A. curvidens, in the herbarium of the University 
of California, has been examined by the writer through the 
kindness of Professor H. M. Hall. It exhibits. certain differences 
from typical A. polycarpa, but none that are constant. The 
stems and bracts are attacked by a fungus, probably a rust, and
