The rhizome of the only plant in the herb is vertical 40 mm long and 

 consisting of short internodes (5 mm. long), very thin at its lowest end and 

 there producing a bushel of rootfibres, covered with short scales and increa- 

 sing in thickness unto the upper end where the leaves are beginning. 

 From the nodes alternating, very long creeping rootfibers are coming forth, 

 no tubers, no thickened roots. 



The leaves are densely conferted imbricating with their sheathing base. 

 The spike is seemingly axillary, its base enclosed in the leaf sheath at the 

 top of the rhizome, surrounded by a few large sheathing scales and three 

 unto five leaves. In our specimen there are two spikes, the younger appa- 

 rently issuing from a side branch of the old rhizome. 



Habitat: Borneo occidentalis prope Montrado in monte Opi, 300 M, les^. 

 Teysmann (5 nov. 1874.) 10916. 



This species is very conspicuous by the long slender radical, long 

 peduncled racemose inflorescence, with large distant and patent bracts. In 

 the young spikes the bracts are evidently somewhat imbricate for they surpass 

 the internodes 3 or 4 times in length, but in the adult spike they are diverging, 

 remote and leaving the rachis quite free. It is apparently very near to 

 G. malaccanum K. Sch. (Scaphochlamys Baker). 



Qastrochiius angustifoliiim Hall. 1898, 358. 



This species has been described in an ample way by Hallier as to 

 the colours and dimensions of all parts. There are however to be added 

 some interesting details regarding the inflorescence and flowers : The ascen- 

 ding top of the rhizome forms a short supraterraneous stem, bearing a 

 tuft of bifarious imbricate leaves, separated by short internodes (5 — 10 mm. 

 long). There are no petioles, the narrowed base of the linear-lanceolate 

 concolorous blades passing immediately into the long (70—100 mm.), 

 channeled sheaths, which are purplish brown, mottled in their lower part.
