 sometimes a, height of 18 ft. The involucre is as often suppressed as developed. 

 P. mlincimm, Karstenianum, Berteroawwm, and vestitwin of the Species Klioum appear 

 to be all villose forms of this without an involucre, and P. spectabile a, subglabrous 

 form. See Griaebaoh's West Indian Flora, p. 691.

 wing into lanceolate segm., of which the lowest are again pinnatifid ; texture thin,

Hab. Java, Moulmein, Khaaia.— A doubtful plant, some of the apecimens of which
