483 
from Colorado and Wyoming, are much narrower than in those from the Pacific Slope. 
Near Terrys Peak, altitude 1,900 m., July 6; Rochford, altitude 1,700 m., July 12 
(No, 506). 
Specimens, collected among peat moss, below Sylvan Lake, 4 miles south-southwest 
from Harneys Peak, altitude 2,000 m., July 18 (No. 507) are much smaller, 3 to 6 dm. 
high, slender, few-flowered, less pubescent, with finer lobes to the leaves and bluer 
flowers, the hoods of which are more semicircular in outline. 
Actza spicata rubra Ait. Hort. Kew. ii, 221 (1789). 
Professor Greene regards this as specifically distinct from A. spicata. Perhaps it 
is so, but the characters pointed out which are to separate 4. spicata from A. rubra 
are not constant, at least in Scandinavian specimens of the former. Even the fruit 
is sometimes bright red in them. 
Rare: Elk Canyon, altitude 1,200 m., June 29 (No. 508). 
Actza spicata arguta (Nutt.) Torr. Pac. R. Rep. iv, 63 (1856) ; Actwa arquta Nutt. ; 
Torr. & Gr, FI. i, 35 (1838). 
This often has the fruit white and much larger and more elongated than in the red- 
fruited variety. Perhaps they are distinct, but I could not find any other character 
that would separate them. 
Little Elk Canyon, altitude 1,100 m., July 18; Custer, altitude 1,650 m., August 15 
(No. 509). 
BERBERIDACEZ. 
Berberis aquifolium Pursh, Fl. i, 219 (1814); Berberis repens Lindl. Bot. Reg. t. 
1176 (1828). 
Without doubt this is the original Berberis aquifolium Pursh, and Lindley made a 
mistake when he supposed that the name belonged to the taller species of the Colum- 
bia River basin. Lindley’s statement that Pursh’s drawing was made from Menzies’s 
plant, that is, the B. aquifolium! of Hooker and of Lindley, is evidently wrong, as 
Pursh does not cite Menzies as having collected it. The plate was made froma 
specimen of Lewis’s collection, and it as well as the description shows that the plant 
belongs to what has been known as BL. repens Lindley.? Sweet, in British Flower Gar- 
den, says: “ Mr. Lindley’s observations on B. aquifolium are wrong; the very speci- 
men figured by Pursh is now in his herbarium in Mr. Lambert’s collection; the 
name B, repens published in the Bot. Reg. must therefore be disused.” 
In canyons: Hot Springs, altitude 1,100 m., June 12; Little Elk, altitude 1,200 m., 
June 28 (No. 510). 
PAPAVERACE#. 
Argemone alba Lestib. Bot. Belg. ed. 2, iii, 183 (1799); 1. albiflora Hornem. Hort. 
Hafn. 489 (1813-15).3 
In draws among the foothills. Hermosa, altitude 1,025 m., July 24; 15 miles east 
of Custer, altitude about 1,400 m., July 23 (No.511). 
FPUMARIACESA. 
Capnoides aureum (Willd.) Kuntze, Rev. Gen. Pl. i, 14 (1891); Corydalis aurea 
Willd. Enum. 740 (1809). 
Rare: Elk Canyon, on the railroad embankment, altitude 1,200m., June 29 (No. 512), 
'This must take the name Berberis nutkana (DC.) Kearney, Trans. N. Y. Acad. xiv, 
29 (1894); Mahonia aquifolium nutkana DC. Syst. 11, 20 (1821). 
2One leaflet in Pursh’s figure (tig. 1) may belong to B. aquifolium Hook.; at least 
this was Watson’s view. 
3 See my notes, p. 149 of this volume. Mr, Prain has shown (.Journ, Bot, xxxiii, 329) 
that P. albiflora is antedated by P. alba. Both are based on specimens from the 
Southern States. Mr. Prain thinks that the plant of the Western plains is distinct, 
and names it 4. intermedia, I can not, however, find any constant character that 
will separate the two.
