it is suspected that the specimen is an abnormal one, deformed by 
the parasite. 
ATRIPLEX OBOVATA Mog. Chenop. Enum. 61. 1840 
Atriplex Greggit S. Wats. Proc. Amer. Acad. 9: 118. 1874. 
When Watson prepared his account of the North American 
Chenopodiaceae he seems to have overlooked Moquin’s name. 
The type collection of A. obovata, obtained by Berlandier, was 
cited by Watson under his new species A. Greggit. Atriplex 
Jonesii Standley (A. sabulosa Jones, 1903, not Rouy, 1890) is 
very close to A. obovata and should, perhaps, be regarded as only 
a form of it. The two seem, however, to have separate ranges. 
ATRIPLEX GARDNERI (Mogq.) Standley, N. Amer. Fl. 21:66. 1916 
Obitone Gardneri Moq.; De Candolle, Prodr. 13?: 114. 1849. 
Atriplex Gordoni Hook. Jour. Bot. & Kew Misc. 5: 261. 1853. 
Atriplex eremicola Osterhout, Bull. Torrey Club 25: 284. 1898. 
The name Obione Gardneri has been neglected by all American 
botanists, possibly because of an impression that the plant was 
of South American origin. The type locality is given by Moquin 
as “‘Ad La Platte,’’ and the collector as Gardner. Hooker, how- 
ever (loc. cit.), pointed out that the specimen was ‘really obtained 
by Gordon along the Platte River in North America. A fragment 
of the original collection (Gordon 251) in the Gray Herbarium shows 
that it is the same as the plant described by Osterhout as Atriplex 
eremicola. Since Moquin never changed the specific name first 
applied, the present writer prefers to maintain it in its original 
form. 
ATRIPLEX CANESCENS (Pursh) Nutt. Gen. 1: 197. 1818 
The authority usually given for the above combination is 
James, but this is incorrect. Nuttall first made the combination 
Atriplex canescens (based on Calligonum canescens Pursh), and 
although he described a different plant at the time he made the 
transfer of name, he must be credited with the suthorehip of the 
binomial. 
The species has an unusually wide range and shows very ap- 
preciable variation in almost every character. The extensive
