62 PASTURE AND RANGE. 
The plant arises from a perennial rootstock. It has 
alternate, palmately lobed leaves which resemble those 
of certain of its near relatives, the Lark- 
spurs, with which it is often confused, especi- 
ally in the younger stages. The flowers, too, are arranged 
as in Larkspurs. They are large and one of the. ir- 
‘regular coloured sepals forms the “hood.” The five small 
petals are all alike. The stamens are numerous and the 
three to five carpels are partly united to form a horned 
seed capsule as in the Larkspurs. Though similar in 
_many respects, Monkshood and Larkspur may be easily 
distinguished when in flower by the presence of the hood 
in one case and the spur in the other. 
The Plant 
 PASQUE FLOWER—Anemone patens L., var. Wolfgangiana 
(Bess.) Koch. 
Other Common Names: Prairie Crocus, Prairie Ane- 
mone, American Pulsatilla, Prairie Smoke. 
Willing mentioned this plant as causing the death of 
sheep in Alberta, concluding that the trouble was due 
to the formation of felt-like balls (phytobe- 
zoars) of the hairs with which the whole plant 
is plentifully provided. In addition to this 
Pammel notes the presence of a very acrid poison, a crys- 
talline substance anemonin, which, in the fresh plant, has 
given much inconvenience to collectors, producing an 
inflammation of the eyes and even blistering the skin 
where wet by the juice. The drug is used by homeeo- 
pathists.
