ligula-lobes. The leaf blade is somewhat coriaceous dgid, shining green 

 ' above, somewhat glaucous on the back side. The costa and sheath are pale 

 purplish brown, marmorate. All parts are covered more or less densely with 

 the long thin appressed hairs, so common in the genus. This division of the 

 herb into a multifoliate, commonly sterile (rarely flowerbearing) shoot and a 

 unifoliate (rarely bifoliate) flowering shoot are notyet described as faraslknow. 



The inflorescence is enclosed within the 20 mm. wide leafsheath 

 and the large outer bract, it is shortly peduncled with the enclosing leaf 

 (as in G. panduratiim, only much shorter) and the peduncle is quite hidden 

 by the large outer scales. The spike is very dense bracteate but the rachis 

 is rather longer than in G. pandiiratum, 25 mm. long and bearing + 20 

 alternating membranous hairy bracts at distances of 1— 2 mm. Those are 

 all inserted at the ventral side of the rachis, which is denudate at the 

 backside, thus the inflorescence is essentially equal to that of G. pulcherrimum 

 Wail; only the distances between the bracts are much shorter than there, and 

 the bracts themselves, being excluded from light, are white and hairy. 

 The flower is involucrated by a convolute bracteole shorter by 1/3 than 

 the corolla tube and much longer than the calyx. 



This species was collected by Nieuwenhuis, No. 936 and 939 Herb, bog, 

 in central Borneo at Tebululan-Teputing in 1896-97. There are no notes. 

 It flowers every year in the Hort. bog. on a rather dry place in a humus 

 containing soil during the rainy season. The white and red flowers are 

 small and hidden.
