being H. humilis. Later* he changed the name to A. decumbens 
convallarius. Even at that time, however, he had a misconcep- 
tion of certain species; for, on a later page of the same article, 
he changed Astragalus junceus (Nutt.) Gray to A. diversifolius 
roborum and labeled with this name specimens belonging to 
H. campestris. 
Macbridet united A. campestris and A. junceus, regarding 
“the relative length of the calyx-lobes and the presence or 
absence of black pubescence”’ as ‘trivial variations’’ and of 
“no practical taxonomic value.’’ Perhaps they are so and per- 
haps H. campestris, H. junceus and H. junciformis should be 
only one species, but he has used one of these characters, the 
longer calyx-lobes, together with the presence of lateral leaflets, 
as a character to separate his A. campestris diversifolius (Gray) 
Macbr. from the typical form of the species. These characters 
are just those that characterize the type. 
Only two of the specimens cited by Macbride under the variety 
diversifolius are found in New York herbaria: the first of these 
is Nuttall’s, from the “sources of the Platte,” Wyoming, which 
represents the type collection of H. orthocarpus Nutt.; and the 
second is Baker 242, from Cedar Edge, Colorado, which matches 
the type of H. campestris in every respect. Evidently Macbride 
has misinterpreted A. diversifolius A. Gray (see below). Of 
the specimens in the Gray Herbarium, Canby 84, from Helena, 
Montana, is H. junceus; so also are Watson 92 and Nelson & 
Macbride 1292, both from Idaho. The rest represent the typical 
H. campestris, except Macbride & Payson 3183, in flower only, 
from Clyde, Idaho, which may be H. orthocarpus. In the 
herbaria of the New York Botanical Garden and Columbia 
University, the following specimens of H. campestris are found :— 
Wyominc: Nuttall. 
Utan: Glenwood, Ward 227; Hooper, Leonard 98; Tropic, 
Jones 5312h; Mandan, Mulford 118; Salt Lake City, Garrett
