2 THE FLORA OF THE NORTHERN TERRITORY. 



Rubiaceee. Spermacoce scabra. 



Myrtacese. Eucalyptus Spenceriana. Tristania grandiflora. 



In addition the following new species of Leguminosse had previously been 

 described by Ewart and Morrison (Proc. Royal Soc, Vict., Vol. 26, p. 152, 

 1913) :— 



Isotropis argfentea. 



Jacksonia anomala. 



Psoralea luteosa. 



Tephrosia pubescens. 



Very little is yet known as to the economic properties of the plants of the 

 Northern Territory, more particularly as regards their fodder value or poisonous 

 properties. Dr. Gilruth obtained data during his first visit of the food values of 

 certain grasses, which were identified and pubhshed in the 19th Contributions 

 to the Flora of Austraha (Proc. of the Royal Soc. of Victoria, 1912, Vol. XXV., 

 p. 105). In the present work these and similar records are given where it has 

 been possible to obtain them, together with information as to valuable wood 

 and other economic properties, including all cases in which plants are known to 

 be poisonous or are suspected of poisonous properties. In this respect many of 

 the Leguminosse of the Northern Territory more especially come under sus- 

 picion. 



Few of the 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 hst. Brachysema undulatum grows in other parts of Austraha, and 

 causes mechanical injury. Canavalia obtusifolia causes gastro-enteritis in 

 stock. 



Several species of Cassia are considered poisonous, and, according to 

 Greshoff, this also applies to Cassia Sophora and C. Sturtii. 



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

 these one, C. Mitchelli, grows in the Northern Territory. Three species of 

 Erythrina and two of Erythrophlseum have been recorded as poisonous, but 

 they do not include any of the species growing in the Territory. The Asiatic 

 Flemingia congesta is a taenifuge, but the F. Uneata of the Territory has not 

 been tested. Many species of Gastrolobium are poisonous, but only one 

 incompletely tested species (G. grandiflorum) is included in the present 

 list. 



Indigofera boviperda, however, has in West Australia been responsible for 

 large losses of stock. The genera Phaseolus, Psoralea and Sesbanea include
