Anagallis arvensts, L. Order Primulacej;. 



A common weed in cornfields in Europe, and known as the 

 " Scarlet Pimpernel." Its seeds are poisonous to birds, and 

 the whole plant has the reputation of being deleterious. 



Andropogon halepensis, var. Epposus, Stapp. Order Gramine^e. 



This is the " Johnson Grass " or " Evergreen Millet." Mr. 

 Burtfc Davy says of it in the ** Transvaal Agricultural 

 Journal " : — " One of the most pernicious weeds ever intro- 

 duced by human agency." He also says : " It only thrives 

 well on rich moist soils where other and more profitable crops 

 such as lucerne may be grown. It is, moreover, a veritable 

 pest in agricultural lands and in orchards, and one that is 

 almost impossible to eradicate. So bad has it become in 

 California that a law against it was passed by the State 

 Legislature at its session in the winter of 1902-3. "He also 

 says quoting from the Pacific Rural Press " If we could name 

 an easy way to extirpate Johuson grass our fortune would be 

 made. The fact of the matter is that it is practically impos- 

 sible to make a clearing of it from any piece of land where it 

 chooses to stay." Dried specimens of this grass may be seen 

 in the Colonial Herbarium, and living plants in the Botanic 

 Garden during the summer months. 



Argemone mexicana, L. Order Papaverace^e. 



A native of Mexico, which has been introduced and become 

 naturalized in most tropical countries. In the West Indies, 

 it is known as "Yellow Thistle," in Mexico as " Fico del 

 Inferno " or Davil Fig ; the sap is yellow on exposure, acrid 

 and has been used medicinally ; the seeds have narcotic pro- 

 perties and contain an oil which is cathartic and emetic. In 

 Natal the plant is only met with in the coast districts. 



BlDENS BIPINNATA, L. Order COMPOSITiE. 



This plant is founu in most tropical countries, but is 

 fortunately rare in Natal, so far as known to us it has only 

 once been collected in Natal ; and was found by the writer in 

 the vicinity of a large Mission Station ; it is not included in 

 the earlier list of Natal Plants, and has not become common 

 though it is nearly 30 years since it was first noticed in the 

 colony. It is very closely related to Bidens pilosa, the well 

 known "Black Jack." 



Bromus maximus, Desf. Order Gramineje. 



This grass is a native of Western Europe, and the 

 Mediteranean regions, and has long been naturalised in Natal 

 and other parts of South Airica. In the "Natural History of 

 British Grasses," by E. J. Jjowe, F.R.S., it is said to 1?© rare iu
