COCKERELL: NorTH AMERICAN SPECIES OF HymMENoxys 473 
Uran.— Mt. Ellen, Henry Mts., Garfield Co., Utah, 10,000 
ft., July 25, 1894, WZ. £. Jones: top of Salina Pass, 8,200 ft., 
June 16, 1894, MW. E. Jones. The Salina Pass material is poor ; 
that from Mt. Ellen is good, and looks very like some specimens 
of H. Richardsoni ligulaeflora, especially those from Montana. 
However, it has the pale foliage of pumi/a, and the comparatively 
short pappus-scales, hardly 24 length of disc-corolla. The achenes 
are of the long type. 
AssINiBpota. — Medicine Hat, June 2, 1894, John Macoun ; 
Cypress Hills, August, 1880, John Macoun ; Wood Mountain, 
June 6, 1895, John Macoun. This was confidently expected to 
be true 7. Richardsoni, the material coming from localities about 
200 miles (or some less ?) south of Carlton House. It resembles 
#1, Richardsoni in the conspicuous flowers, with large orange rays, 
and the inner bracts, though fimbriate, do gradually taper to the 
apex, as in the figure of ?. Richardson, The foliage much resem- 
bles that of subsp. pumila, and the stature is about the same, 
though the largest plants are as much as 10 cm. tall. The Wood 
Mountain plant is more dwarfed than the others (height 6 to 8 
cm.), and has the achenes short (a Richardsoni-character), their 
hair shining pale ferruginous ; the pappus-scales are ferruginous 
basally, and have long linear awns, the whole 34 length of disc- 
corolla, as in subsp. /igu/aeflora. The Medicine Hat plant, with 
the same conspicuous orange-rayed heads, has the achenes fairly 
long (considerably over half length of disc-corolla), their hair 
strongly ferruginous; the pappus-scales are light ferruginous, 
darker at base, ¥ length of corolla, the oval portion very large, 
the apical portion linear and about % length of the whole. In 
this plant the achenes are much longer than in true H. Richard- 
sont The Cypress Hills material is poor ; the achenes are long, 
as in subsp. /igu/aeflora, the pappus-scales also very long ; hair of 
achenes ferruginous. 
It will be apparent from the above that the Assiniboia plants 
are variable and are not exactly HW. Richardsoni or subsp. pumila, 
Assuming the figures of P. Richardsoni to be correct, I cannot 
refer them there, and on the whole they go best here. 
It is difficult to decide how to indicate such puzzling forms in 
the nomenclature. In the present paper I shall use the term
