1. Coastal Territory. 
ı. Strand Formation. 
Between low and high tide marks, the sandy beach is quite bare of vege- 
tation ‘). However, the rocks of the hills which project into the ocean at 
Orange County, California, have a large supply of algal growth in this region. 
Fucus serrata, F. fastigiata, Cladophora rupestris, Plumaria elegans and Coral- 
lina offieinalis are the most common sea weeds found here. 
Above flood tide, where there is a beach, it is flat and unbroken by dunes. 
The growth here is almost entirely herbaceous in character. The few woody 
forms are low and have a spreading habit. Oenothera cheiranthifolia var. 
suffruticosa is the common woody form. 
Other characteristic species are: Abronia maritima, A. umbellata, Mesembryanthemum aequi- 
laterale, Franseria bipinnatifida and Convolvulus soldanella. It will be noticed that these forms 
» are quite suceulent. With the exception of Franseria, all have a spreading or creeping habit 
The Abronias are noteworthy in that they have er leaves A gi vertically and the Ieaf 
in different directions. art of many 
The s common to both formations are: Salicornia ambigua, Sesuvium portulacastrum, 
ärtpien alrnien; Sarcobatus Maximiliana and Mesembryanthemum SERAPN Tratu. When growing 
on the coast these forms seem less stiff and hard than when growing ‚inland. 
It may be well to contrast those plants confined to the immediate shores 
of the ocean on the sand of the beach, and those that occur in the tidal 
marshes, or salt meadows in some places. The following is according to S. B.
