Denticulatum (Figs. 64 and 65). — Found by Mr. Barnes ; a small 

 grower, of somewhat congested, stiff make, pinnules very finely cut, 

 the edges resembling small teeth, whence the name, which means 

 small-toothed. It is, however, the peculiarly pretty, crispy char- 

 acter which distinguishes it from the normal and renders it an 

 acquisition.
