 apex, those on superior side of pinna slightly longest except sometimes on lowest 

 pair of pinnfe, in fully fertile fronds cut down to a winged rhachis, leaving up to 

 6 pail's of tertiary segments free, which again are deeply cut down into three or 

 more unequal-sided lobes either simple and non-soriferous, or cleft into unequal 

 horns and then soriferous ; texture herbaceous ; colour of fronds olive green, 

 — of stipes and rhachises more or less pink ; veins of tertiary divisions pinnate 

 in the lobes : veinlets of lobes simple or abruptly branched into two parts curv-

 the base of each cleft lobe across -the forked veinlet ; invol. persistent, nearly 

 as wide as the cleft lobes. (Plate I.)
