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 Harnevs Peak, altitude 2,000 m., July 18 (No. 507) are much smaller, 3 to G 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. 



Actaea spicata rubra Ait. Hort. Kew. ii, 221 (1789). 



Professor Greene regards this as specifically distinct from A. gpicaia. Perhaps it 

 is so, but the characters pointed out which are to separate A. 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). 



Actaea spicata arguta (Nutt.) Torr. Pac. R. Rep. iv, 63 (1856) ; Acta'a argufa Nutt. ; 

 Torr. & Gr. Fl. 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). 



BERBERIDACEiE. 



Berberis aqmfolium Pursh, Fl. i, 219 (1814); Berheris repens Lindl. Bot. Reg. t. 

 1176 (1828). 



Without doubt this is the original Berheris aqui/oUum 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 from a 

 specimen of Lewis's collection, and it as well as the description shows that the plant 

 belongs to what has been known as B. repens Lindley.- Sweet, in British Flower Gar- 

 den, says: '"Mr. Lindley's observations on B. aquifolium are wrong; the A'cry 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 1,100m., June 12; Little Elk, altitude 1,200 m., 

 June 28 (No. 510). 



PAPAVERACEiE. 



Argemone alba Lestib. Bot. Belg. ed. 2, iii, 133 (1799); A. alhiflora Hornem. Hort. 

 Hafn. 489 (1813-15).' 



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). 



FUMARIACE.a3. 



Capnoides aureum TWilld.) Kuntze, Rev. Gen. PI. i, 14 (1891); Corj/dalis aurea 

 Willd. EuiiiM. 710 (IXOit). 



Rare: Elk Canyon, on the railroad emb.inkment, altitude 1,200m., June 29 (No. 512). 



'This must take the name Berheris nutkann (DC.) Kearney, Trans. N. Y. Acad, xiv, 

 29 (1894); Mahonta aquifolium nutkana DC. Syst. ii, 20 (1821). 



'^One leaflet iti Pursh s figure (fig. 1) may belong to />'. aquifolium Hook.; at least 

 this was Watson's view. 



' See my notes, j>. 149 of this volume. Mr. Prain has shown (Jouru. P.ot. xxxiii, 329) 

 that /'. albiflora is antedated by /'. alba. Both are based on speciniejis I'roni the 

 Southern States. Mr, Prain thinks that the plant of the Western plains is distinct, 

 and names it A. intermedia. I can not, however, find any constant character that 

 will separate the two.
