 probably simple, the upper part 4-pinnate, ovate in outline, the main 

 rachis 7 — 9-stelical, sparingly foliate, when dry fuscous and irregularly 

 grooved, the lower axillary leaves deltoid, somewhat broader than long, 

 with the corners bluntly rounded; pinnae ascending, to 20 cm. or more 

 long, the largest lanceolate-ovate or eiongate-subtriangular, the rachis + 

 7 mm. broad including the lateral leaves; pinnulae close, the lower 

 spreading, with the secondary pinnulae forked or sparingly pinnate;
