52 IIANUNCULACE.E. Delphinium. 



D.* Burkei Greene. " Stems one or several, a foot high or more, erect, not slender, from 

 a manifestly woody-fibrous root, leafy at or near the ba.se only : foliage and lower part of 

 stem seeming glabrous, though somewhat puberulent under a lens ; upper part of stem and 

 the inflorescence clothed with a short villous-hirsute pubescence : leaves 2 inches broad, 

 deeply parted into many linear and oblong-linear obtusish segments, the texture rather 

 fleshy: raceme rather long and narrow, the pedicels being equiU and quite erect : sepals 

 deep blue, pubescent exteriorly, spur rather long, usually blunt, nearly straight and hori- 

 zontal; petals conspicuously white, or perhaps ochroleucous : ovaries densely appressed- 

 villous: follicles unknown." — Greene, 1. c. 183. — "Snake Country probably in Idaho," 

 Burke. Said by Prof. Greene to have been referred by Dr. Gray to D. Andersonii, but this 

 is not sliown by specimens in herb. Gray. From the characterization quoted above, the 

 species would appear near if not identical with some forms of D. distichum. 



16. ACONITUM, Tourn. Monkshood, Wolfsbane. (Ancient Greek 

 and Latin name, of uncertain origin.) — Perennial herbs (of the cooler parts of 

 the northern hemisphere) ; with palmately lobed or dissected leaves, and showy 

 flowers in terminal racemes or panicles. Seeds in ours densely squamellose. — 

 Inst. 424, t. 239, 240 ; L. Gen. no. 448 ; Gray, Gen. 111. i. 43, t. 16. — For con- 

 venient brevity the upper sepal is here called the hood. 



A. Napellus, L., of Europe, the officinal Aconite, Monkshood, or Wolfsbane, not rare in 

 gardens, is said to have escaped sparingly from them in some places, at least in Lower Canada 

 and Newfoundland. 



* Stem erect (or in A. uncinatum with flowering summit declining), from tuberous thickened 

 conical or naplform roots: hood hetmet-shaped or cap-shaped; flowers blue, rarely vary- 

 ing to white or pale yellow. 

 A. delphinifolium, DC. Stem a foot to a yard high, strict, above more or less cinereous 

 with a close retrorse pubescence : leaves deeply ])arted, divisions laciniately cleft into lance- 

 olate or linear lobes : flowers large : hood low, not over semicircular, almost symmetrical 

 and slightly crescentic in outline, only short-attenuate at base and apex : lower sepals as 

 long and half as broad as the lateral : follicles oblong. — Syst. i. 380 ; Reichenb. Monogr.

 A. Noveboracense, Gr.\t. Stem erect, 2 feet high, leafy, only the summit and strict 

 but ratiicr looselv several-flowered raceme pubescent : leaves membranaceous, rather deeply 

 parted; the broadly cuneate divisions 3-cleft, and the lobes incised into lanceolate or broader 

 lobelets : hood (over half inch long) gibbous-obovate, with rounded casque-shaped summi 

 or back about the length of the basal portion and of the porrect descending beak : lower 

 sepals small and narrow: follicles oblong. — Bull. Torr. Club, xiii. 190. A. uncinatum,

 A. Willard (1857), and below Oxford, F. V. Coville (1885) .2 Habit of some forms of 

 the following; in the hood between it and the preceding. The specimen of herb. 

 Le Conte, referred to by Torrey under ^. uncinatum, is not extant, and may be of either this 

 or that species. 

 A Columbianum, Nctt. Stem commonly 2 to 4 feet high, lax, the upper part or at least 

 the loose and sometimes flexuous racemes or panicles pubescent and mostly viscid : leaves 

 deeply cleft or barely parted, usually into rhombic-ovate or obovate-cuneate divisions, these
