several localities, especially about Nelson; but it does not seem to 

 have spread beyond that district. Cockayne thinks this is the plant 

 which is forming large colonies in parts of Central Otago. 



Aster imbricatus, Linn. 



First recorded by Kirk in 1895 from a ballast heap in Wellington. 

 Introduced from Buenos Ayres in 1892. It increased to a small 

 extent, but I do not think it has established itself. It has not been 

 noticed in any other locality. 



Aster subulatus, Michx. 



Cheeseman (19 19) says: 



This plant was first noticed in the vicinity of Auckland about twelve 

 years ago, and soon became plentiful, especially in moist places on harbour 

 reclamations, by roadsides and ditches, etc. It is a native of the United 

 States, where it is principally found in brackish-water marshes, ranging 

 from New Hampshire to Florida. 



Reported by Carse in 191 5 from Mongonui County, as " spreading 

 rapidly in all soils and situations." 



Calotis lappulacea, Benth. 



In the Manual (1906) this is reported to have been found in three 

 locaHties, viz., in Poverty Bay by Bishop Williams, Nelson by Kingsley, 

 and Banks Peninsula by Brown and Kirk. (Fl., Feb. to April.) 



Erigeron canadensis, Linn. Canadian Flea-bane 



First recorded in Hooker's Ust in 1864. Cheeseman considers it 

 one of the earliest introductions into New Zealand, and records it 

 as common in 1882 throughout the Auckland district. Kirk had 

 already noted it in 1877, from several places in WeUington Province, 

 but stated it was not nearly so abundant as in Auckland. (FL, Feb. 

 to April.) 



In the Manual (1906) Cheeseman states that it is abundant through- 

 out both islands; which is only partially correct, however, as it is 

 not found (e.g.) near Dunedin, nor in most parts of Otago. 



Erigeron linifolius, Willd. 



First recorded in Hooker's list of 1864 as Conyza ambigua. In 

 1882 it was found in several localities in the Auckland Province, 

 Northern Wairoa, Whangarei, Matamata, etc. In the Manual (1906) 

 it is stated to be abundant in the Auckland provincial district, rarer 

 southwards to Marlborough and Westport. W. W. Smith recorded 

 it from Ashburton in 1903. (FL, Feb. to April.)
