650 MANUAL OF POISONOUS PLANTS 



states that the chemistry of the plant has not yet been worked out, but that all 

 parts are poisonous, the root especially deadly. Lehmann states, however, 

 that the first species is not as poisonous as was formerly supposed; sheep and 

 hogs eat it, although it is poisonous to horses. In the latter it is said to produce 

 • paralysis of the hind legs. Berula erecta of Europe and North America is poison- 

 ous, especially the root. It is a smooth aquatic perennial, with compound simple 

 pinnate leaves; leaflets linear oblong, serrate to cut-toothed; flowers white, and 

 fruit globose. 



In Australia according to Maiden the Apiuni leptophyllum when grown in 

 damp soils is poisonous. The wild parsnip of that country is one of the most 

 poisonous plants of Australia, no antidote to it being known. The Chaerophyl- 

 lum temulum of Europe causes colic and stupor. The parsley is not ordinarily 

 considered poisonous but is said to be injurious to birds. The gum resin am- 

 moniac found on the stem of Dorema Ammoniacum is acrid. The resin re- 

 sults from the sting of an insect. The genus Ferula from which Asafoetida is 

 derived causes haematuria and bleeding at the nose.
