 The S Portulacastrum, a native of India, and the only Lin- 

 nsean species of the genus, has been divided by De Cando lie 

 into S. fiedunculatum, sessile, and revolutum. The first is com- 

 mon on the sandy sea-coast in the Southern States. Mr. J^u t- 

 ia II is, I believe, the only Botanist who has observed S. ses-^ 

 sile in this country. Mr. Elliott thinks the capsule of 

 Sesuvium has been incorrectly described as cut round near the- 

 base. He remarks that it has towards the summit three su- 

 tures distinctly marked, but the base is membranaceous and 

 vei-y delicate, and appears to decay or tear as the seed becomes 

 mature, suffering the more substantial summit to fall off with- 

 out opening But in some of my specimens there were many 

 ripe causules, which appeared to open transversely all rounds 

 by a wtii defined margin.
