INTRODUCED WEEDS 



(including some USEFUL ONES), 



Although Mr. Hemsley's list is an enumeration of all the 

 " indigenous " plants known to inhabit the island, he has seen fit 

 to include therein certain introduced plants; perhaps it would be 

 desirable to exclude these, and to place them in a separate list. 

 Unless this be done there will be no finality in a list of the flora, 

 one reason being that weeds are sometimes exterminated by 

 human agency, a circumstance as yet unknown with any species 

 indigenous in the island, and which if they do not decrease cer- 

 tainly do not increase in number of species. 



The islanders now seem alive to the danger of allowing noxious 

 weeds to obtain a footing. For example, the Bathurst Burr 

 (Xanthiiitn sjiinosumj and the Black Thistle (Carduns lanceola- 

 tus) were got rid of by concerted action. 



There were also a few patches of the dangerous weed. Nut Grass 

 (Cypei'us rolundus), but this has been exterminated. There were 

 also a few patches of Wild Onion ( Allium frayrans, Vent.) which 

 were nursed by one of the settlers as a pretty plant. When its 

 nature was discovered it took four years to exterminate it.
