XI—Acclimatisation of Useful Plants.

So far as I could ascertain, there are no indigenous plants of economic value in Tonga which could be acclimatised in New Zealand; and the much higher latitude in which the Tonga Islands lie probably precludes the possibility of any such attempts succeeding. Many European plants grow well here; limes, for example, flourish so luxuriantly that they are planted for fences. Great annoyance has been caused on some of the islands by the introduction of the guava fruit tree, which has spread so rapidly by means of seeds and "suckers" as to become an intolerable and ineradicable nuisance, akin to the furze in some parts of New Zealand.
