STANDLEY: CHENOPODIACEAE 423 
however, is restricted to the Rio Grande Valley of southern New 
Mexico, western Texas, and northeastern Chihuahua. The bracts 
of the Californian plant are sufficiently distinct to entitle it to 
specific rank, and the ranges of the two species are widely separated. 
ATRIPLEX HILLMANI (Jones) Standley, N. Amer. Fl. 21: 48. 
1916 
Atriplex argeniea Hillmani Jones, Contr. West. Bot. 11:21. 1903. 
This plant seems to have a limited distribution, being confined 
to Nevada and southeastern Oregon, so far as specimens show. It 
differs conspicuously from A. argentea in the form of the bracts 
and leaf blades. Representative collections are the following: 
OrEGON: Malheur, &c., Cusick 1263. NEVADA: Leonard Creek 
Ranch, Griffiths & Morris 346; Battle Mountain, Kennedy 4oor, 
A. E. Hitchcock 586; Lemmon Valley, Kennedy 2081. 
ATRIPLEX MINUSCULA Standley, N. Amer. Fl. 21: 51. 1916 
Most closely related to A. pusilla (Torr.) S. Wats., a species 
of eastern Oregon and northwestern Nevada, from which it is dis- 
tinguished by its larger bracts, these subhastate and denticulate 
or crenulate, not ovate and entire. The following collections have 
been observed: 
CALIFORNIA: between Tulare and Tulare Lake, 1892, Palmer 
2728 (type); Laton, Kearney 33, 34; near Poso, Coville & Funston 
1249; without locality, 1872, Torrey. 
ATRIPLEX PENTANDRA (Jacq.) Standley, N. Amer. Fl. 21: 54. 1916 
Axyris pentandra Jacq. Sel. Stirp. Amer. 244. 1763. 
Atriplex cristata Humb. & Bonpl.; Willd. Sp. Pl. 4: 959. 1806. 
In view of the fact that this plant was first described as a 
species of the Old World genus Axyrts, it is perhaps not remarkable 
that its earliest name has been so long overlooked. More prob- 
ably it has been neglected because its identity can be confirmed 
only by a consultation of Jacquin’s illustration, which occurs in 
one of the rarest of botanical works.* This shows that the name 
Axyris pentandra applies to the common plant of southern Florida 
and the West Indies, heretofore known as Atriplex cristata.
