Pale tawney-olive, somewhat greener at the tops of the 

 stems, which are 4-5 inches long, distantly pinnate, with 

 short patent branches, which again appear minutely pinnu- 

 late, with perigonial branchlets. Leaves scarcely imbricated, 

 oblique, nearly round. Lobules scarcely attached to the 

 leaves, the upper ones subacute, slightly incurved towards 

 the stem. This differs from Jung, platyphylloidea, Schweinitz, 

 by the narrower and flatter shoots, the more distant leaves, 

 their minuter cells, and by the lobules and stipules being 

 fringed at their bases, with a few spinous teeth. We have 

 not seen M. subciliata, L. et Lind. ; ours, however, disagrees 

 with the characters given of that species by the rotundate, 

 (not ovate), leaves by the want of any decurrent ciliato- 

 dentate base to the leaves, by the lobules not being imbri- 

 cated, nor ligulate, but obovate, and by the runcinato-dentate 

 bases of both lobules and stipules.
