Distribution. 



Sumatra: Mt. Ophir, Talamau, n. west declivity 18(30 M., common in 

 forest, BüNNEMEljER 666, 9/5-' 17, „vern. name Paar Korang. Flowers 

 violet, bracts red." Id, 695 13 5-'! 7, .vein, name Puctr sirah. Flowers 

 red, bracts red." 



The rhizomes creeping above the earth sustentée! by descending roots 

 remember Hornsiedtia pininga and rubra, but the roots are covered with 

 rootfibres, and probably no true aerial roots as in both the cited species. 

 They are cut of at a hundred mm. from the rhizome and the section has 

 3—4 mm. diam. The rhizomes are invested with amplexicaul scales, thai 

 are 20 mm. long, densely imbricating, broadly ovate acute with a fine 

 thorny mucro, thinly coriaceous, the nude parts smooth, shining, striate, 

 not reticulate, the basal parts and the axis tomentose. 



Sympodia! members are present of 160 mm. length, about 12 mm. thicks 



The stems are about 10 mm. thick, probably still young, for the 

 adult stem should be 5 M. long. Leaves 260 mm. long X 65 ; petiole 

 about 10—15 mm. 



The spikes arise from -the rhizomes near the leafstem, they consist 

 of a short thin peduncle sen.sim dilated towards the globose spike; both 

 covered by densely imbricating, broadly obovate thorny pointed convex 

 scales, quite smooth and striate, shining, about 50—70 mm. diam, ail 

 flowerbearing. There is no real difference between the central and peri- 

 pherica! bracts, no involucrum. 



\ have reduced this species to Geanth.us only provisorily, for by 

 the possession of siaminodes it departs from all other species of tiiis 

 genus, formerly described, but i am unwilling to propose a new genus 

 before having studied more and better materials. 



The inflorescence and flower are different from that of any division 

 of the Amomum group though it shows some characters of all. 



There is no common involucrum composed of large vacuous outer 

 bracts, rigid and protecting the membranaceous inner flowerbearing 

 bracts, as in Hornsiedtia, or showy as in Achasma and Nicola ia, but all 

 bracts are quite similar, very hard and resistant and each protecting its 

 extremely thin and tender flower. 



The fiowers are small, the tube short quite connate to the filament; 

 no faux like prolongation of the tube above the insertion of petala. The 

 lip is calceoiate with thickened edges, without auricles, such as are never 

 wanting in any of the other groups (excepted Euamomum), covering 

 and protecting the anther, it is also peculiar by being recurved.
