The specimens in Mr. Binsfcead's herbarium being in fruit, I have made 



them the typo of the spocies. It is a very beautiful plant, very near to 



P. speriosissima (under wliich name it stood in Binstead^s herbaiinm, deter- 



mine<l T think by Mitten), but ilitforing quite markedly in the leaf-characters 



italicizi^d jibove. 



I liave careFully compared original specimens of i\ speciosissima (Sulk)

with the Philippine P. l^^'^g^f 



whatever, I'\ spccioslssima^ as hinted by Brothrrus, must certainly be looked

upon as a synonym. 



The branching is rather erratic. The stipes may be unbranehed, when the 

 frond becomes regularly elli[itical ; or it may send out two or three 

 secondary divisions, eacli of tlioso being bipinnately branched, in which case 

 the frond is more flabellatc ; these secondary divisions^ again, may bo 

 branched from the base, or thev may remain unbranehed for some distance 

 up, like the main stipes, in wliich case the stipitate secondar3^ frond has a 

 peculiar app*^arance, sueh as is seen in some sj^ecies of St/mpJiysodonteUa, 



(The drmcings^ PL 2Q, fffjs. 6, c^ exaggerate slightly the di^erettves between 



the tiro .yyecies,)
