We possess only tbe single specimen of tbis distinctly marked species of Grammitis, which was 

 brought from Demerara by our valued friend C. S. Parker, Esq. It has the forked habit of some 

 species of TcEnitis, especially of T.furcata, and the divided state of T. graminifolia ; but the fructi- 

 fication is decidedly that of a Grammitis.
