lines, in 1903 by W. W. Smith. It was also growing freely on the 

 flats on the Ashburton River. It is now common on some Canter- 

 bury river beds. In the Manual (1906) it is reported as occurring 

 in both islands as "an occasional escape from gardens." (Fl., Sept. 

 to Oct.) 



Cytisus candicans, Lam. 



Apparently first recorded by Cheeseman in the Manual (1906). 

 It is abundant in both islands. (Fl., Sept. to Nov.) 



Ononis arvensis, Linn. Rest-harrow; Wild Liquorice 



Introduced into Southland in 1870 among grass-seed, but did not 

 succeed in establishing itself. 



Medicago sativa, Linn. Lucerne ; Alfalfa ; Purple Medick 



Probably introduced very much earlier, but first recorded in 1882 

 by Cheeseman as occurring in cultivated fields near Auckland, but 

 not common. Abundantly cultivated in many parts of the country 

 but only occurs naturalised as an escape. (FL, Sept. to Jan.) 



The flowers (in Europe) are visited by Apis mellijica, Bombus 

 terrestris, B. hortorum and B. lapidarius. 



Medicago lupulina, Linn. Black Medick 



First recorded in Hooker's list in 1864, but certainly introduced 

 at a much earlier date. Now very abundant in fields and waste places. 

 (FL, Sept. to Feb.) 



Medicago denticulata, Willd. Toothed Medick 



Also first recorded in Hooker's list in 1864. Abundant throughout 

 all cultivated districts. (FL, Sept. to Jan.) 



This and the next species are included among the noxious seeds 

 in Schedule 3 of the Noxious Weeds Act, 1900. 



Medicago maculata, Willd. Spotted Medick 



First recorded by Hooker in 1864. Cheeseman in the Manual 

 (1906) says: "Abundant in the Auckland Provincial District, local 

 elsewhere." It is a most abundant weed in many parts of Otago, 

 especially in the coastal districts. (FL, Sept. to Dec.) 



Melilotus officinalis, Lam. Melilot 



First recorded in Hooker's list in 1864; no doubt introduced very 

 many years earlier. Cheeseman in the Manual (1906) reports it as
