is, however, introduced erroneously as A. Napellus. The poison- 
ous principle is pseudoaconitine. The amount of pseudoaconitine 
found in the tubers of this species may, according to Prof. 
Dunstan, reach as much as 0'50 per cent tStapf). 
24. A. laeiniatuvi, Stapf. sp, nov. 
Vernacular name : — Kalo Bikhmo. 
Habitat : — Subalpine and Alpine Himalaya of Sikkim and 
adjpining Tibet. 
Roots biennial, tuberous, paired ; daughter-tuber conic- 
oblong, often rather drawn out into a slender point, 3 5-6 cm. 
long, about 1 5-2 cm. thick, simple or divided, with filiform 
root-fibres, which are generally not much thickened at the base, 
brown externally, fracture whitish or pale brownish, almost 
horny, taste indifferent or very slightly bitterish, followed by 
a tingling sensation ; cambium continuous,, forming a sinuous 
ring in cross-section ; mother-tuber similar, usually much 
shrunk and thinner. Innomlion-biul an acute cone, up to l cm. 
high, .outermost scales are very short, clasping, soon decaying 
after sprouting. Stem erect, stiff or flexuous, 6 to 9 dm. high, 
simple terete, slender to rather robust, finely pubescent in the up- 
per part, with adpressed reversed hairs, otherwise glabrascdnt or 
quite glabrous and shining, drying usually chestnut-brown. 
Leaves scattered ; basal 5-6, rarely 8, decayed at the time of 
flowering, rather distant ; intermediate and upper leaves up to 
10, approximate or congested, petioled, petioles rather slender, 
2 5-7 5 cm. long; blades somewhat fleshy, finely pubescent or 
almost glabrous, reniform, rarely cordate-orbicular in outline, 
with an usually wide and shallow sinus, 4-7, rarely to 10 cm., 
from the sinus to the tip, 7-12 cm. across, 5-pedati-partite 
almost to the base in the inner, to f-J in the outer incisions, 
inner divisions sub-equal, rhomboid from a narrow cuneate 
base up to 5 cm. wide, 3-lobed to the middle, lobes narrow, 
inciso-dentate or laeiniate, laciniaj lanceolate or linear, acute 
or acuminate, outermost divisions asymmetric, mostly unequally 
2-lobed, otherwise similar to the inner, but smaller. Inflores- 
cence racemose or usually loosely paniculate, few to many-
