This is an exceedingly doubtful plant. It is supposed 

 by J^fu 1 1 all to be the Arenaria peploides of our sea-coast ; 

 but this cannot be the case if the synonym oi C o I d e n is cor- 

 rect, as the detailed description below will prove. I have 

 always been of ojiinion, that this long-lost species is nothing 

 more than the Stellaria media, in which the flowers are fre- 

 quently triandrous, and the leaves a little fleshy. In the Muhlen- 

 bergian Herbarium there is a specimen labelled Holospeum, 

 without a specific name, which is certaily S. media. Wal- 

 ter's PoLYCARPON uniJlorum,\ which Pursh refers to Ho- 

 LosTEUM succulcntum, appears lo be quite a different plant ; 

 perhaps Sesuvium fiedunculatum.
