COCKAYNE, L., On the importance of New Zealand as a 

 field for Botanicai Study and Research. (Trans. 

 Australasian Association for the Advancement of Science. 

 1904. p. 291—298. Issued 1905.) 

 The foUovving are suggested as lines of research for which 

 New Zealand is suited. The rain-forests and Nothofagus 

 forests contain many plants as yet little investigated. The coasts 

 have Aigae, halophytes, and sand dune plants of which little 

 is known. The alpine and sub-alpine zones require investigation 

 as regards distribution and adaptation of plants. The author 

 has already shown by his own papers that the New Zealand 

 xerophytes and heterophyllous plants are well adapted for re- 

 search in experimental morphology. The numerous islands of 

 the region afford facilities for studies on distribution, and the 

 adaptation of plants introduced from other countries.
