Passiflora Herbertiana and P. aurantia have been 

 accused of poisoning stock. P. suberosa var. minima and 

 P. foetida are common naturalised weeds in Queensland ; 

 both are powerfully cyanophoric, and have been accused 

 of poisoning stock. P. alba, another naturalised species, 

 is poisonous to stock, and is the subject of a special paper 

 by S. Dodd^ ; several tests of it carried out by us have 

 alwaj^s given negative results. It is, however, recorded as 

 cyanogenetic by Pel^rie*^. ^
