variations. The high rainfall of the west favours arborescent forms 

 which contrast strongly with the grasslands of the drier eastern 

 coast. The physiognomy of the coastal Vegetation presents distinct 

 features, including the tufted stiff yellow leaves oi Scirpus frondosus 

 covering miles of sandy shores, and the roundish black bushes ot 

 Plagianthus divaricatiis on estuaries and salt meadows; in the moister 

 regions a form of rain forest may fringe the shore. Other topics 

 briefly discussed are: Endemism on the small coastal Islands, the 

 Southern and northern limits of coastal plants, local and limited 

 distribution, mountain plants on the coast, primitive and modified 

 formations. The occurence of a number of coastal plants Inland is 

 regarded as evidence of former arms of the sea extending inland. 

 The coastal plants which are also found inland are tabulated, and 

 these along with the occurrence of many introduced plants of a 

 distinctly inland type lead to the conclusion "that the coastal plants 

 as a whole occupy their peculiar Station not from choice, but from 

 necessity, and that they are ordinary inland plants driven thence 

 by competition". The paper concludes with a list of typical coastal 

 plants, which gives also their general distribution (endemic, Austra- 

 lian, subantartic, or cosmopolitan) and that within New Zealand, 

 also notes on Station and life-form. W. G. Smith.

Gaya lyallii var. ribifoUa has been described as evergreen at 

 low altitudes and deciduous above 1000 M. The author adds to his 

 previously stated opinion to the contrary, that G. rihifolia was ob- 

 served in many places to be leafless in April and May; seedlings 

 and young plants retained their juvenile foliage, but plants from 

 "cuttings" were deciduous. Whether the type G. lyallii is evergreen 

 at low altitudes requires confirmation. W. G. Smith.
