the preceding. Hard to distinguish from A. ccerulea by any mere descrip- 

 tion, as they exhibit transitions at all points. The following appear to me 

 to be the chief differences : flower, at least in Southern specimens, always 

 golden yellow; sepals and petals nearly the same length, 1'; inflorescence 

 paniculate, and continuing until terminated by cold weather. Common in 

 damp ground and ravines of the mountain streams in the White Mountains 

 and Mount Graham of Arizona. It is certainly no exaggeration to say 

 that I have, near the Willow Springs, seen ten acres so completely covered 

 with this plant in full bloom, that everything else was lost sight of. Ari- 

 zona, at 7,000 to 10,200 feet altitude. (196.) 



Delphinium scopuloeum, Gray (PI. Wright. 2, p. 9). — 2£° high, pu- 

 berulent throughout; lower leaves with petiole 4-6', becoming shorter 

 above ; leaves round in outline, 3-5-parted, each division narrowly cune- 

 ate, again variously cut-lobed and toothed ; raceme slender, one foot long; 

 pedicels hairy, twice as long as the bract at base, one or two bractlets 

 usually immediately below flower ; spur over half an inch long, thickish, 

 hairy, slightly curved, with markedly thickened extremity and one-half 

 longer than the puberulent sepals ; lower petals nearly as long as the 

 sepals, slightly hairy within, upper one with a somewhat shorter blade, its 

 spur nearly as long as that of the sepal ; carpels 3, smoothish. Flowers 

 are scattered loosely along the stem at intervals (when developed) of 

 an inch. A species as variable as it is elegant. Tanks south of Camp 

 Apache, Ariz. (263.) Altitude, 5,625 feet. 



Delphinium Menziesii, DC. — Nevada; Snake River, Colorado. Dr. 

 Vasey informs me that the plant (No. 96) which I published in the list of 

 Colorado plants in 1874 as D. elatum, L , var., he has found, on comparison 

 with the specimens in the Department of Agriculture Herbarium, to be I). 

 Mensiesii- 



Delphinium elatum, L., var ? occidentalis, Watson. — Plant taller (5°) 

 and more vigorous in every way than the others ; leaves three-lobed, 

 with each lateral lobe again divided, and all the lobes variously gashed 

 and cut-toothed. The ample foliage, the long, hooked spur, acute sepals, the 

 distinct spur on the lower petals, so far as they go, make the limits of this 

 species in my collection tolerably well defined. Utah.
