Notes
In Blumea, l.c., I treated P. rostrata as being conspecific with the Bornean P. radians, but after having seen recent Philippine collections with ripe fruits I am convinced that the two are well distinct.
In 1936 UITTIEN referred P. rostrata to the synonymy of the New Guinean P. longirostris. The two are certainly closely related, but the shape of their fruits differs considerably, so that I prefer to keep them apart. Some additional minor differences corroborate this view.
In both P. rostrata and P. longirostris the beak of the fruit is variable in length. Though in RAMOS 23642 from Lake Polog and in JACOBS 7666 from Sierra Madre the beak is shorter than in ELMER 16150 from Mt Bulusan, the type collection of P. rostrata, I refer them to that species on account of the remaining characters. See also under P. parvibractea.
