11. Tryon. — " Plants Poisonous to Stock." 

 Bailey and Gordon. — " Plants reported Poisonous and 

 Injurious." 



CoRNEViN. — " Plantes veneneuses." 



J. Kennedy. — " On Loco-\veed (Astragalus mollissi- 



}}}US).'" 



T. Williams. — " Some Plants Injurious to Stock, &c." 

 The reports of the Agricultural Departments of the 

 United States, Queensland, the Cape, New South Wales, 

 &c., contain several articles on this question which are of 

 great interest. 



PAPILIONACE/E. 



Abrus precatorius (Climbing Shrub).— This plant has small red 

 seeds with black specks commonly called " crab's eyes." 



In 1870 the Indian Commission reported that numerous cases of 

 poisoning of live stock caused by the seeds of this leguminous plant 

 had been recorded. 



Astragalus (Under-shrub). — This genus is accused in the United 

 States of being responsible for loco disease. Th-e species iiiollissimus 

 is reputed to be most dangerous, and Astragalus le7itiginosns and 

 Hornii are also injurious. 



AnagyrJs foetida (Shrub). — This is a shrub of which every portion 

 is poisonous, but it offers little danger owing to its rank smell, which 

 deters animals from browsing it. The poisonous seeds have some- 

 times been mistaken for those of the bean owing to their resemblance 

 to these latter. 



Brachysema undulatum (Shrub).— According to F. Turner this 

 plant is considered poisonous in Western Australia. 



Canavalia obtusifolia (Liane). — A dangerous plant which is encoun- 

 tered in all tropical countries. 



Crotalaria aiata (Shrub). — An Indian plant which, according to a 

 report of the Queensland Agricultural Department (i8gi), is poisonous 

 to live stock in that country. 



Crotalaria sagittalls (Shrub). — This Crotalaria is one of the loco 

 ivceds of U.S.A. In Bulletin No. 2>2>-, A. Williams attaches such 

 importance to the injurious properties of this plant that he applies 

 the name of crotalism to a disease in horses which feed upon it. It 

 seems to be the same as loco disease and indigo disease. 



Although this plant is reputed to be very dangerous in New South 

 Wales and Queensland, in India, where it is very widely distributed, 

 it does not appear to have any harmful effect on cattle.
