Eat Island, growing only withiu the spray of the blowhole at 

 the south-west corner ; abundant there, but seen nowhere else. 

 The soil at this spot is reef -rock covered with guano in parts. 

 The plant grows in tlie holes formed by the weathering of the 

 rock, and makes bright green patches visible for some distance. 



The species is very near ^S*. portulacastrum, L. ; but I believe 

 it to be quite distinct in the colour of the flowers, which ai*e not 

 even tinted with pink or purple, and in the number of styles, 

 never less than three in S. portulacastrum ; but in this sjiecies 

 there are but two, and these much shorter than in the latter 

 plant.
