Collected at the foot of Laramie Peak, in the Laramie range, in a 

 canon where it occupied the dry crevices in abrupt clifts. 

 Delphinium azureum (?) Michx. Fl. Bor. Am. i, 314 (1803). D. Car- 

 olinianiim, Walt. 



Not quite typical but probably a form of this species. Saratoga, 

 June 1893, J. D. Parker. 

 Delphinium bicolor, Nutt Journ. Acad. Phila. vii, 10. 



Our earliest Larkspur, in dry loam soil of ravines and hillsides. 

 Telephone Canon, May 23, 1894 (No. 48); Table Mountain, 

 June 28, 1895 (No. 1385). 

 Delphinium Geyeri, Greene. 



A good species, immensely abundant on the Laramie Plains. 

 Frequently greedily eaten by hungry cattle with fatal results, 

 caused by bloating, hence the local common name, " Poison 

 Weed." Laramie Hills, July 10, 1894 (No. 400); South Laramie 

 Plains, July 31, 1895 (No. 1552). 

 Delphinium scopulorum glaucum, Gray. Bot. Gaz. xii, 52. D. glati- 

 ciiin, Wats. 



In the mountains at 8,000-9,000 ft.; Union Pass, August 10, 



1894 (No. 874); Laramie Peak, August 7, 1895 (No. 1599). 

 Delphinium scopulorum subalpinum, Gray. Bot. Gaz. xii, 52. 



A very beautiful alpine form. LaPlata Mines, 11,000 ft., August 

 22, 1895 (No. 1761). 

 Aconitum Columbianum, Nutt. T. & G. Fl. i, 34. 



Two marked forms occur: The typical one, tall, large-leaved 

 and dark blue or purple flowered; the other, repeatedly observed, 

 has light yellow flowers, the plant is smaller, leaves smaller and 

 less pubescent. Less striking differences have sometimes been held 

 to be specific, so it seems proper that this at least bear the varietal 

 name ochroleticmn. The former is common in thickets on mountain 

 streams. Collected at Snake River, August 21, 1894 (No. 939); 

 Cummins, July 29, 1895 (No. 1521). The latter, less frequent, in 

 similar locations ; collected at Cummins and in Centennial Valley 

 and observed at Laramie Peak.

White and red berried forms occasionally found growing together.
