762 THE FLORA OF NORFOLK ISLAND, 



Nicotiayia Tabacum. The Tobacco seems quite at home. 

 Peppermint is plentiful in some watercourses and damp 

 grounds. 



Tragopogon porrifolius (Salsify) is wild, and so is 



Foinir.ulum vulgare (Fennel). 



The Celery plant also is wild. Watercress is plentiful. 



Introduced Plants. 



List C. — Plants introduced for Cultivation, and which have got 

 more or less beyond control. 



Crucifer^. 



Matthiola incana, R.Br. (?). The common Purple Stock has 

 abundantly run wild near Emily Bay. 



Geraniace.e. 



Oxalis reptaas, Sol., Endl., Prod. Norf. 128. 



Leguminos.e. 



Cytisus sp. Introduced as a hedge at the Melanesian Mission. 



Luplnus sp. A purple-flowered species in Edward Buffett's 

 paddock, and also in the Mission ground. The amount of seed 

 is wonderful. 



Vicia sat'iva, Linn. I have seen a specimen from the Island 

 labelled V. sepium, Linn., which is, in my opinion, also V. saiiva, 

 Linn. 



Vicia hirsuta, Koch. 



Cacte.e. 



Opuntia brasilieiisis, "A Prickly Pear" (bright yellow flowers, 

 thin joints, two-spined). In Mr. Rossiter's land and at the 

 Mission, near the gate. A plant near a building near the pier. 

 I was told that the people have often tried to exterminate the 

 Prickly Pear by cutting it and throwing it into the sea, but fail 

 to exterminate it. They might be instructed how to exterminate 

 it by means of a solution of arsenic in soda. I did not see much 

 of the weed, and it could be got rid of readily enough.
