Flora of Australia. 153 



plants on the present list have been tested as yet from this point of 

 view, but poisonous species are known to occur in the following 

 genera : — Bauhinia has three poisonous species, one of which is a 

 fish poison, and another an anthelminthic, but no data are available 

 for the species of this genus on the present list. Brachysema undu- 

 latum grows in other parts of Australia, and causes mechanical 

 injury. Ganavalia obfusifolia causes gastro-enteritis in stock. 



Several species of Cassia are considered poisonous, and, accord- 

 ing to Greshoff. this also applies to Cassia Sophora and G . Sturtii. 

 No less than five species of Crotalaria are recorded as poisonous, 

 and of these one, G. Mitchelli, grows in the Northern Territory. 

 Three species of Erythrina and two of Erythrophlaeum have been 

 recorded as poisonous, but they do not include any of the species 

 growing in the Territory. The Asiatic Flemingia congest a is a 

 taenifuge, but the F. lineafa of the Territory has not been tested. 

 Many species of Gasfrolobimn are poisonous, ])ut only one incom- 

 pletely tested species (G. (jrandiflorum) is included in the present 

 list. 



Indifjofera hoviperda, however, has in West Australia l)cen 

 responsible for large losses of stock. The genera Phastfolus, 

 Psoralea and Seshanea include poisonous species, but apparently 

 none from the Territory. Rhynckosia minima is, however, poisonous 

 according to Greshbff, and the same may be found ultimately to 

 apply to some of the species of Swainsona and Ttphrosia. Several 

 species of the latter genus are well-known fish poisons, and this 

 applies to at least one species from the Territory, namely, Tephrosia 

 purpurea. In this direction there will Ije mucli \\iirk to be done in 

 the future.
