CALYCIFLORZ IIs 
used to feed rabbits, from which reason the latter are 
detestable to many people, or even poisonous, as Kek 
contains some principle, like many umbellifers, of a 
noxious character. 
The root is long and deeply rooted, with branching 
rootlets which make it difficult to eradicate it, as the 
least bit left in the ground appears to have the 
power of starting a fresh plant into existence. 
The stem is hairy below, with a whitish down, erect, 
hollow, reddish-white in parts, stout, bearing nume- 
rous leaves. | 
The leaves are two to three times pinnate, and: are 
dark or light green, varying greatly in appearance in 
this respect and in the toothing and division of the 
leaflets, which are pinnatifid, ovate, and coarsely 
serrate. There are no bracts. The bracteoles, as 
they are called, are oblong, lanceolate, ciliate, green, 
spreading or turned down, and are often pink. The 
flowers are in umbels with a peduncle, and terminal ; 
the flowers are white, the fruit glabrous, a quarter of 
an inch in length. The fruit has a short beak, and 
the carpels are smooth. The stem is 3 to 4 ft. 
high. The flowers are in bloom from April to 
June. Itis a perennial. 
The numerous small flowers in large flat heads 
render the flower conspicuous, and each contains 
honey accessible to all insects. Thereare five petals, 
and five stamens alternate with them. The anthers 
ripen first. Over seventy different kinds of insects 
were noted by Muller as visiting this plant.
