The predominating trees in the Lowland Forest are Corynocarpus 

 laevigata*) and Olearia Traversll ; in the Tableiand Forest, Senecio 

 Huntll and Dracophyllum arboreum. Both of the latter also oeeur in 

 lowland swamps. but neither Corynocarpus nor Olearia Traversii ascend 

 to the tableiand. 



The palm Rhopalostylis, is also coniined to the lowlands. Among 

 the native plants most rapidly diminishing in number is the beautiful 

 endemic Myosotidium, and among the introduced plants the blackberry, 

 Rubus f mucosus, „seems to be the only one which is a menace to any 

 large proportion of indigenous plants". 1t is spreading all over the 

 island, and considerable areas of native Vegetation have been completely 

 replaced by it, and in many places it forms impenetrable thickets it 

 would be interesting to know whether this introduced blackberry presents 

 much Variation, because it is largely reproduced from seed, and it is all 

 probably the issue of one original stock. 



Mr. Cockayne's observations on the origin of the Chatham 

 Island Flora, on the effects of introduced plants. etc. are highly 

 instruetive and suggestive. I will conclude this rather long notice with 

 an extract on this part of the subjeet: „Introduced plants spread 



especially where the indigenous Vegetation has been disturbed. Where 

 the plant-covering of a region is in its virgin condition, and there is 

 nothing to bring any introduced plants except the wind, they often fall 

 to become established. Thus Mr. T. F. Cheeseman saw only two 

 naturalised species on the summit oi Pirongia Mountain (North 

 Island, N. Z.) and these he supposed had been accidentally brought 

 by the surveyors." W. Botting Hemsley.

*) It may be of interest to mention here that I shall shortly publish 

 descriptions of two new species of Corynocarpus, the discovery of which 

 seems to support the Maori tradition that their ancestors brought 

 C. laevigata with them to New Zealand, or, at least to lend it some 

 probabiiity. W. B. H.
