Teijsman in West-Borneo and which I named G. laxifloriim. Here also the 

 slender spike rises directly from the rhizome and is sheathed by a few 

 leaves. The subcoriaceous cymbiform subpatent bracts are 30-35 mm long 

 and distanced about 10-15 mm., the spike with its peduncle 150 mm. The 

 bract envelopes 3-7 flowers. Each flower is semi-involute by a small bract 

 (12 mm. long) and accompanied by two very small bracteoles. Comparing 

 this with the infl. of G. pulcherrimum the difference in habit is so striking 

 that only a strict comparison of the flower-structure shows the affinity of 

 these species. Quite similar is the inflorescence of another species in the 

 Herb. Bog., collected by Burkill (Pahang, 1143) named G. siibbiloba, not 

 yet published. Here the spike is only 100 mm. long, flexuose and bears 4 

 cymbiform bracts distanced 5—8 mm., the peduncle is villous, the spike 

 deglabrate. There are no flowers, only a glabrous young fruit enclosed by 

 the top bract. There are only two radical leaves with long imbricating sheaths 

 and embraced by a large sheathing scale. The spike is radical and enclosed 

 by the leafsheaths. 



To this group belongs also a rather different species: G. angustifoliuni 

 Hallier. Here the stem or ascending rhizome is thick, woody, erect, and 

 bears several (+ 10) alternating approximated sheathing and imbricate 

 leaves, the spikes rise from the leafaxiis and sometimes from the outer 

 sheathing scales, the rachis is composed of 2 or 3 thin flattened internodes, 

 5—10 mm long and a rudimentary filiform top internode; it is flexuose 

 (zigzag), and bears commonly two or three cymbiform, rather stiff brown 

 coloured bracts, which each include only one flower enveloped by the thin 

 membranous convolute bracteole. 



The flower is very similar to that of G. longiflorum Wall, the saccate 

 lip being adnate to the base of the stamen but the connective is projecting 

 a litle above the cells, forming a minute 3-crenate appendage, visible to 

 the nude eye, but so short that it was quite overlooked by Hallier and 

 that Schumann ranges this species under Gastrochiius where it certainly 

 belongs. 



Beyond these four species which form what ! would call the scap- 

 hochlamys-gwup, here must be ranged : G. laxifoluis Ridl., and G. longipes 

 King and Prain; all belong to Paragastrochiliis. 



They all are conspicuous by the slender axis and rigid, cymbiform. 

 distanced subpatent persistent bracts, by their origin from the leafaxiis or 

 directly from the rhizome, sometimes from the centrum of the leaves but 

 never directly terminating a long or short leafbearing stem as was the 

 case in the first treated of group. 



G. lougiflonim, the second type species of Eugastrochilus has a somewhat 

 different inflorescence because of the more dense imbricating bracts; but 

 the bracts are distanced with spiral not unilateral insertion, their consis-
