GRAMINE^ 495 



Arundinaria macrosperma, Michx. 

 Reported by Cheeseman in 1882 as lingering in several old Maori 

 cultivations, but cannot be looked upon as truly naturalised. In 19 17 

 he states it still lingers on in one or two abandoned cultivations, 

 but no instance has been observed of its reproducing itself. 



Brachypodium pinnatum, Beauv. 



I collected this grass in 1897 near the Ross Creek Reservoir, 

 Dunedin, but have not found it since. It has not succeeded in 

 establishing itself. 



Poa annua, Linn. Annual Meadow-grass 



Probably one of the earliest introduced grasses ; first recorded in 

 1864 in Hooker's list. The commonest of all grasses on roadsides 

 and in waste places, especially where regularly trodden on. 



Poa compressa, Linn. 



First recorded by Cheeseman in 1 882 as occurring on the Auckland 



Isthmus, but not commonly. In the Manual (1906) reported as 



occurring, somewhat sparsely, in fields and waste places in the North 



Island. „ . ^ . , , , 



Poa pratensis, Lmn. Meadow-grass 



No doubt a very early introduction; first recorded in Kirk's list 

 of introduced plants in Great Barrier Island in 1867. One of the 

 most abundant grasses in fields and waste places in all parts of New 

 Zealand. In some districts, it takes exclusive possession of the pastures, 

 and is most difficult to eradicate. It is in such parts looked on as a 

 dangerous "couch" grass, and is a pest in cultivation. 



Poa trivialis, Linn. 



First recorded in Hooker's list in 1864. In 1877 stated by Kirk 

 to be frequent about Wellington and other places in the district. 

 Reported by Cheeseman in 1882 from waste places about Auckland, 

 and occasionally in pastures. In the Manual (1906) said to be not 

 uncommon in fields and waste places throughout both islands. 



Poa nemoralis, Linn. 

 First recorded from Southland in 1870 by the author; then by 

 Cheeseman in 1882 as occurring in the Auckland Domain. In the 

 Manual (1906) reported as occurring sparsely in shaded places in 

 both islands. 



Glyceria aquatica, Wahlenb. Reed-grass 



First recorded from the Ashburton district in 1903 by W. W. 

 Smith. Later by Petrie from the Taieri Plains and Catlins River. 

 It is not uncommon in Otago and Southland.
