Leaflets lanceolate, subinequilateral, pointed ; midrib narrow, but rig'id ; 

 secondaries parallel, equidistant, arched and camptodroine. 



The leaflets are S"*" to 6™" long and 1.5''" broad at or below the middle. 

 naiTowed to the base, lanceolate above, and some of them sliohtlv inequi- 

 lateral. They have the same form and size as those of P. ai/fjusfifoHa and 

 1'. lanceoluta Ett.' They differ from those of the European species by the 

 nervation being somewhat more distinctly marked, the secondaries, seven 

 to eight pairs, distinctly arched, parallel, and by the somewhat broader size 

 resembling small leaves of some Lauriueai. They may, however, represent 

 the same species.
