NOTES ON THE NATURAL HISTORY AND PHYSIOGRAPHY OF N. B. 



129 



A Preliminary Ecologic-geographic Classification of the Vegetation of 



Neiv Brunswick. 



(Primary Divisions in part after Warming.) 



Section 1. Groups in adaptation to other organisms — Includes Climbers, 

 Epiphytes, Saprophytes, Parasites, Symbionts, Insectivora 

 Myrmecophila, etc. All of these groups are of minor import- 

 ance in our vegetation. 



Section 2. Groups in adaptation to external physical conditions. 



I. Xerophytes [Desert- Plants) — Typical forms 



entirely wanting in our Flora ; repre- 

 sented only by xerophytic characters in 

 species living where transpiration nor- 

 mally exceeds supply, either because 

 water drains off quickly or for other 

 reasons is available in but small quan- 

 tity. 



II. Halophytes (Strand Plants) — But a few 



herbaceous species in our Flora ; some 

 inland colonies. 



III. 



IV 



Hydrophytes ( Water-plants) — Very well 

 developed in our Flora. 



Mesophytes {Normal Plants) — Comprises 

 the great bulk of the vegetation of this 

 section of America. 



1. Original Vegetation. 



2. Effects of Cultivation. 



A. Rocky hills, etc. 



B. Sea-cliffs.
