The genus Niphobolus of Kaulfuss, is one among the Poly- 

 podioid Ferns that is retained by some Botanists and rejected 

 by others. Few as are its characters, it is generally easily 

 distinguished by its habit and its stellato-tomentose covering. 

 Its venation is very indistinct and difficult to be seen and to 

 be accurately represented, and is said by Presl to be different 

 in different species. Then as to specific differences they de- 

 pend mostly on the outline of the fronds which are uniformly 

 undivided. In favor of this being considered distinct I may 

 observe that its fronds are so narrow and so uniformly small 

 (4 inches being the extreme length) that it is at once distin- 

 guishable from every other kind known to me.
