— Iva oraria and Baccharis halamifolia — all salt and brackish 

 marsh species are herbaceous, and grass-like forms are pre- 

 dominant. The appended list includes some of the commoner 

 representative species.

Along the sandy beaches which fringe the coast two classes of 

 plants may be distinguished, viz., those able to grow in the more 

 or less saline soil of the beach proper, and those restricted to the 

 aeolian sands of the low dunes which usually cover the beach 

 on its landward side. Peculiar to the beach itself are: 



A triplex arenaria 

 Salsola Kali* 

 Arenaria peploides

Characteristic of the dunes are:

The ecological relations of the salt marsh and beach floras will 

 be given more special treatment in a later paper, but it may be 

 further noted here that not a few of the inhabitants of these areas
