oblong-ovatc, with a small basal auricle; with this exception 

 they are uncut on the margin, merely being minutely serrate. 

 The pinnae arc placed so close to each other that they overlap 

 fully one half of their width, and arc consequently very 

 much imbricated; the basal pinnae are descending, and the 

 remainder slightly ascending; they also arch forwards, so as to 

 place the stipes in a hollow between the row of pinnae on
