The material collected consists of a longitudinal half of a fragment of 

 rhachis, about 38 cm. long, with pinnae attached. The pinna-segments 

 closely resemble the pinnse of P. moluccana, but differ, of course, in being 

 dichotomously disposed at base. 



The remarkable fronds of this fern, rising to a height of 3 m. from the 

 ground and growing in clumps, must form a conspicuous feature in 

 the savannah landscape. It is surprising that so well developed a species 

 should not have been recorded previously, unless, indeed, its distribution is 

 extremely limited.
