The flowers are very small, but singularly pretty if examined with a magnifier of 

 moderate power.

 Organs of Pilularia globulifera. In a Letter to R. H. Solly, Esq., 

 F.R.S. and L.S. By William Valentine, Esq., F.L.S.

 ment of the Theca, and on the sexes of Mosses,'* and ' On the exis- 

 tence of Stomata in Mosses,'t has in the article before us recorded

 teresting British plant, of rather unfrequent occurrence. We do not 

 strictly observe the order adopted by the author in treating on the 

 various parts of the subject, but however, like him, we begin with the 

 sporules. 



The involucrum of Pilularia globulifera contains two kinds of bodies 

 occupying distinct sacs. The first kind are found chiefly but not exclu- 

 sively in the upper part of the involucrum j they are round, not more
