are wide in fruit. Scales rather obtuse with a slight membranous 

 border. Flowers three on each side, the highest being largest. : 

 Salt marshes. August. Annual. 



At the latter end of the season the lower part of the stem 

 shrinks and becomes woody ; the plant however is strictly an- 

 nual. 



This plant agrees exactly with specimens from England and 

 the continent of Europe. It is however more branched and 

 slender than the engravings usually published of the European 

 plant. 



*SALICORNIA MUCRONATA. Dwarf Samphire. 



S. humilis, herbacea articulis inferne tetrago- 

 nis, superne compfessis, truncatis spiculis oblon- 

 gisj squamis mucronatis. 



Low, herbaceous ; joints quadrangular at bottom, 

 compressed and truncated at top ; spikes oblong with 

 mucronated scales. 



Stem erect, leafless, the joints quadrangular at bottom, widen- 

 ed and entire, not emarginate at top. Branches few, compound, 

 in small plants simple. Spikes lateral and terminal, oblong, four 

 or five times as long as they are wide when in fruit. Scales 

 very acute or mucronate with a slight membranous border. Salt 

 marshes. August. Annual. 



This plant is less than half the height of the preceding, but 

 thicker in all its parts, and always distinguishable at sight 

 Spikes very thick, with remarkably acute scales. It is wholly 

 unlike S. ambigua MX. of which I have southern specimens 

 with slender branches and spikes and obtuse scales. 



Different species of Salicornia are among the maritime plant* 

 employed in the manufacture of sod:). They are used at table 

 as pickles.
