Sumatra: West coast, Padang in mt. Talamau (Ophir), common in 

 light forest, at 20S0 M. (leg. BüNNEMEIJER 20809, 23 5, 1917, „flowers 

 yellow"). 



This species remembers P. chrysocalyx by the description of the spike 

 and flowers, but the shape of the leafbase, petiole and ligula seems to 

 me too different to allow an identification. It is however rather strange 

 that the collector who found this species frequently at the same locality 

 •where BECCARI collected P. chrysocalyx did not collect the latter species. 



The species is curious by the rather loose, narrow invokicral bracts 

 all erect but not closely imbricating so as to form a complete rigid in- 

 volucre as in N atropurpurea. All bracts are rostrate-acumniate, the long 

 tips of the flower bracts exserted above the coroll. In a dried state they 

 are castaneous brown. The long exserted 3-dentate calyces very conspi- 

 cuous by their yellow-sericeous indûment are a little longer than the bracts* 

 the bracteoles are little more than half as' long, bicarinate like other species 

 of the genus and also yellow-sericeous. On other mountains in the same 

 region (Padaugsche Bovenlandeii' in Mt. Talang, Mt. Merapi and Mt 

 Singgalang the collector gathered other forms showing the same type in 

 me construction of flowers and spike and also in the whole habit but 

 very much different by several details. The difference in the shape and 

 hairiness of the ligula is very striking. Neither in the type specimen nor 

 in the varieties any trace of fruit was found.
