NOTES FOR STUDENTS 



. A botanical survey of New Zealand.— We are constantly reminded of the 



remarkable vegetation of this far away-land through the indomitable energy of 



I Cockayne/ whose ecological studies are always of the highest value. The 



Island whose flora is here considered is one of the three that been has long set 

 apart as a preserve through the commendable foresight of the New Zealand govern- 

 ment. Perhaps the most interesting formation of the Island is the forest, made 

 Up of a number of the characteristic New Zealand trees, whose distribution 

 is related to wind in a most striking way. The heaths, the scrub, the strand, 

 etc., are more briefly described, and then follows an interesting chapter on the 

 afiinities of the flora. The paper is accompanied with representative formation 

 photographs, and a list of the species with Latin, English, and Maori names. 

 The New Zealand government, which has made possible Cockayne's study of 

 the island, and which has published this valuable report, is to be most heartily 

 congratulated for its good sense. It is to hoped that the government will find 

 a way to employ Cock.\yne's services for similar work all over the countr}^, and 

 especially because he is the man best fitted for this work. This is an admirable 

 undertaking for any government, and particularly for New Zealand, since its 

 flora is without counterpart elsewhere, and seems to be more than commonly 

 subject to destruction by the ravages of man. — Henry C. Cowles.

cactus, and Azorella formations. All are characterized by a dominance of 

 xerophytic shrubs, but the Hoffmanseggia formation is the characteristic forma- 

 tion of the sandy plateaux, while the cacti dominate more on the stony hills. 

 The Azorella formation is on the higher hills and is closely related to the cactus 

 formation. Above the Azorella are lichen deserts. There are also regions of dunes 

 some of which are dominated by Patagonium, others by Lampaya. Halophytic 

 areas are extensive, some being dominated by Salicornia pulvinaia, others by
