714 PLANTS OF NEW SOUTH WALES, 



being the only species widely distributed), are known to have at 

 least 18 species in Queensland, of which Graptophyllum Earlii, 

 (F.v.M.) is a beautiful shrub rising sometimes to the height of 

 15 feet. The most extensive order of the Monopetalao in New 

 South Wales is that of the Composites, comprehending 52 genera 

 and upwards of 200 species, of which Olearia argophylia (F.v.M.) 

 is perhaps the most remarkable. Mr. Bentham reckons the 

 whole number of Australian Composites at 500, and he has 

 arranged them in 88 genera. There is, however, great difficulty 

 in determining whether some species, common to other parts of 

 the world, are indigenous or not. After having carefully con- 

 sidered the subject, I am of opinion that the following have 

 been introduced : 



1. Centaurea Melitensis, (Linn.) 



2. Centaurea calcitrapa, (Linn.) 



3. Carthamnus tinctorius, (Linn.) 



4. Onopordon acanthium, (Linn.) 



5. Cardiius marianus, (Linn.) 



6. Eupatorium cassabinum, (Linn.) 



7. Erigeron canadensis, (Linn.) 



8. Erigeron linifolius, (Willd.) 



9. Xanthium spinosum, (Linn.) 



10. Tolpis barbata, (Willd.) 



11. Siegesbecha orientalis, (Linn.) 



12. Galinsogea parvi flora, (Cav.) 



13. Bidens pilosa, (Linn ) 



14. Tagetes glandulifera, (Schranck.) 



15. Antliemis cotula, (Linn.) 



16. Chrysanthemum segrtum, (Linn.) 



17. Chrysanthemum Parthenium, (Pers.) 



18. Soliva anthemifolia, (E. Br.) 



19. Gnaphalium luteo-album, (Linn.) 



20. Gnaphalium purpureum, (Thunb.) 



21. Senecio scandens, (DC.)
