CATALOGUE. 11 



with blue. Colorado to the Sierra Nevadas. Wahsatch and Uinta Mountains, 

 Utah, on shaded mountain slopes, 7-9,500 feet altitude ; June-August. (37.) 



Delphinium elatum, L., Var. (?) occidentale. Tall, (5° high,) gla- 

 rous, or densely pubescent above ; leaves deeply 3-5-cleft, the divisions broadly 

 cuneate, somewhat 3-lobed and sparingly gash-toothed, the teeth narrowing 

 abruptly to a callous point ; racemes many-flowered, (often densely so,) 

 simple or panicled ; flowers pubescent, frequently white ; spur longer than 

 the sepals-; lower petals broad, slightly notched^ often erosely dentate, more 

 or less densely bearded, the claw spurred at base. — It is difficult to determine 

 satisfactorily the relations of this plant. It is the D. exaltatum of Bourgeau's 

 collection ; also the D. elatum, Var., of Parry, and Hall & Harbour, from 

 Colorado, though with longer and usually much more glabrous racemes of 

 smaller flowers. It differs from the smaller D. scopulorum in its much less 

 laciniately dissected leaves, and in the lower petals being broader and less 

 deeply lobed, while it seems to be as much unlike European specimens of 

 D. elatum^ in which also the claw of the lower petal is less conspicuously 

 spurred. 1940 of Brewer's California collection, considered a good D. scopu- 

 lorum, has the size and nearly the same foliage, but with all the petals nar- 

 row and bifid. On stream-banks in the East Humboldt and Clover Mount- 

 ains of Nevada, and in the "Wahsatch, 7-8,000 feet altitude ; July-Septem- 

 ber. (38.) 



Delphinium Menziesii, DC. ''Pubescent; leaves 5-parted, divisions 

 2-3-cleft ; lobes mostly hnear, entire ; lower bracts 3-cleft ; raceme 3-6-flow- 

 ered ; spur straight, as long as the sepals ; ovaries somewhat tomentose ; root 

 grumous." — The limits of this species (wherever they may be) scarcely ac- 

 cord with this description. It is the prevalent species on the foothills of 

 Nevada, and a suite of numerous specimens shows a usually scanty pubes- 

 cence; stem rather stout, 1-2° high; the leaves orbicular in outline, 

 5-7-parted, divisions more or less deeply 2-3-cleft; bracts mostly entire; 

 racemes simple, loosely few-to many-flowered ; spur usually curved, longer 

 than the sepals, ascending ; capules glabrous. It differs but little from D. 

 tricorne of the East, and approaches some of the other reputed species of CaK- 

 fornia. From Southern California to Behring Strait; Colorado. Abundant 

 throughout Western Nevada; 4-5,000 feet altitude ; May-July. (39.) It 

 is occasionally seen with pink flowers, (40,) and very rarely with the 

 flowers double. (41.)
