Anthemis Cotula, Linn. Stinking May-weed 



First recorded by Kirk from Wellington in 1877, and later by 

 Cheeseman in 1882 as occurring in waste places in Auckland district. 

 In 1906 Cheeseman reports it in the Manual as occurring not un- 

 commonly by roadsides and in waste places in both islands. (Fl., Feb. 

 to March.) 



Achillea millefolium. Linn. Yarrow; Milfoil 



First recorded in Hooker's list in 1 864. In most cultivated localities 

 in Auckland Province in 1882, "but nowhere abundant." In the 

 Manual (1906) it is said to be not uncommon in fields and on road- 

 sides in both islands. It is very common in many parts of Otago. 

 It spreads in part by underground stems. It is readily eaten by sheep. 

 (Fl., Feb. to March.) 



In Europe the flowers are fertilised by the following flies : Eristalis 

 tenax, Lucilia ccesar, L. sericata, Musca corvina, Calliphora erythro- 

 cephala, Stomoxys calcitrans 1 . 



Achillea tanacetifolia, All. 



In the Manual (1906) it is reported to occur, but not commonly, 

 in waste places and on roadsides in both islands. The only localities 

 specified are in the vicinity of Auckland by Cheeseman, and Lincoln, 

 Canterbury, by Kirk. (Fl., Feb. to June.) 



Matricaria discoidea, DC. 



First recorded by Cheeseman in 1882 as "in immense abundance 

 in waste places about Auckland, and along most lines of road into 

 the interior." Practically the same distribution is given in the Manual 

 in 1906. (FL, Feb. to March.) 



Matricaria Chamomilla, Linn. Wild Chamomile 

 First recorded by Kirk in 1867 in list of naturalised plants in 

 Great Barrier Island. In the Manual (1906) it is said to be not un- 

 common in waste places and cultivated fields in both islands. 



The fruit develops an adhesive mucilage on the surface when 

 moistened, and this may aid in its dispersion by birds. 



Matricaria inodora. Linn. 



First recorded in 1869 by Kirk from the Auckland district, and 

 in 1877 from Wellington. In the Manual (1906) it is said to be not 

 uncommon in fields and waste places in both islands. It is a very 



1 Kerner has pointed out that " along roads where cattle have gone to pasture, 

 one may notice how the leaves of yarrow, scabious, mullein, and similar plants, 

 have been eaten off, while the greater part of their blossoms have been left intact."
