 Salvia eoeeinea, Linn. 



In many cases of course, tlie evidence of introduction is founded 

 on little more than conjecture. Some that are called so are not 

 excluded from our native population on evidence that would 

 exclude them in a court of justice ; but their cause must be 

 pleaded on another occasion. It may be sufficient to say now that 

 it is doubtful whether some or all of the following 13 species may 

 not really be indigenous : — Silene gallica, Linn. ; Stellaria media, 

 Linn. ; Xanthium spihosum, Linn. ; Bidens pilosa, Linn. , Galinsoga 

 parviflora, Cav. ; Taget.es glandulifera, Schranck ; Physalis peruviana 

 Linn. ; Rumex acetosella, Linn. ; Chenopodium ambrosioides, Linn ; 

 Sisyrinehium micranthum, Cav. ; Cgnodon dactylon, Pers. ; Holcus 

 lanatus, Linn. ; Lipocarpka argentea, R. Brown. The last is a 

 beautiful sedge, and has only been gathered in one locality by 

 myself. Bentham, in the " Australiensis," (vol. vii., p. 337) seems 

 to doubt its being indigenous. As far as my observations go, I 

 am convinced that it is not introduced, but is as purely indigenous 

 here as in any other of its habitats. 



Amongst the Graminea) or grasses, it is difficult to say which 

 are and which are not introduced in every case, but I think we 

 may safely say that Lolium temulentum Linn. ; Ceratochloa imiohides, 

 DeCandolle; Poa annua, Linn. ; and Panicum maximum, Linn., 

 are not natives of Queensland. Something might be added about 

 the qualities of the Drunkard's Rye grass, or as I suppose we should 

 say the Rye grass which makes people drunk, as that was the 

 intention of Linnaeus, in calling this weed Lolium temulentum. 

 It is better known to us as wild Darnel, and I believe its poisonous 

 qualities have been made out. Fortunately it is not common, but 

 wherever noticed it should most certainly be extirpated. 



These few notes are far from complete, and I have jotted them 

 down to a great extent from memory. It should be observed that
