Art. XLI. — On the Nativity in New Zealand of Polygonum aviculare, L. 



By T. Kirk, F.L.S.. 



\B.ead before the Auckland Institute, 26th June, 1871.] 



At page 336 of the Transactions of tlie ]S"ew Zealand Institute for 1870, Mr. 

 Travers has given prominence to a difference of opinion that exists between us 

 on the question of the nativity of Polygonu')n aviculare^ L., in the colony. As 

 his conclusion that it is of exotic origin does not appear to me to be supported 

 by the facts of the case, I purpose briefly stating the conditions under which 

 the plant occurs, and placing on record one or two interesting points connected 

 with its distribution. 



The only alleged or inferential reason adduced by Mr. Travers in support 

 of his view is comprised in the following statement : — " The natives, moreover, 

 who suffer much inconvenience from its spi'ead, call it a ' pakeha' or foreigner."
