clusa; vagiiiis binis alternis imbricatis quarum altera laininiftira, involucrata, 

 a bracteolis nuinerosis aequiloiigis cum floribus iiumerosis conflata. 



Flores parvi Calyx parvus tubulosus, apjce spathaceus, bracteola multo 

 minor, pilosulus. Corollae tubus puberulus calyce plus duple longior. Label- 

 lum obovatum apice integrum (?) basi subcanaliculatum, 12X8, faux hir- 

 tellus. Staminodia lanceolata petalis minora. Petalum dorsale lanceolatum 

 apice subcucullatum, lateralia similia Stamen fere G. C«r^/s/7, breve. Anthera 

 subincurva tliecis parallelis oblongis ports dehlscentibus, connectivo crasso 

 hippocrepiformi apice paullum prolongato bifido, an bidentato. 



Habit of G. panduratum but in all parts smaller. The stem, covered 

 by the alternating leaf sheathes, is 60 mm. long and 2 mm. thick, puberulous, 

 the internodes circ. 5 mm. long. Leaf sheaths 40-60 mm., petioles 40 — 25, 

 blades 150—160 X 45—50, of a pale brownish grey colour, paler on the back. 



The inflorescence as in G. panduratum and G Curtisii; bracteoles nu- 

 merous acute. Flower 50 mm. long (in sicco) Bracteole very close con- 

 volute, 27 mm. Calyx 10 mm., ovary linear. Stylode 4 mm. Corolla-tube 35. 

 Dorsal petal 12X4. Lip 12X8 with a white or yellow centralbar in the 

 lower part, bordered by a brown or violet cloud. Faux hairy, dark 

 coloured. Stamen 10 mm. (fil. 3, thecae 6 crest. 1.); cell opening with 

 terminal pores. 



Habitat: Borneo Amai-Ambit, 1080 M., Hallier 3176 B in Herb bog. 

 (unicum !) A very distinct species, not yet described. 



This species is nearest to G. Curtisii, and it agrees in many ways with 

 G. hirtum Ridl 1909, 57. from Sarawak. But in that species there are two 

 leaves only, and the petiole and sheaths are densely pubescent; the petal 

 and lip are only 6 mm. long; the anther crest is rounded. 



Qastrochilus hirtum. Ridl. 1909, 56. 



"Stem short covered with hairy sheaths. Leaves 2 obovate oblanceolate 

 subobtuse mucronulate, much narrowed to the base, 6 — 7 inches long 2 

 inches wide, about 6 pairs of nerves conspicuous, glabrous, petiole and 

 sheath 3 inches long hairy densely. Spike central, subcylindric thick, 2 in- 

 ches long. Bracts lanceolate cuspidate with long acuminate points thickly 

 hairy. Floral bracts lanceolate cuspidate 1 inch long densely hairy. Calyx 

 '/a inch long, ribbed hairy. Corolla white, tube slender cylindric, over an 

 inch long hairy, lobes lanceolate obtuse '/4 inch long hairy. Staminodes 

 narrower acute. Lip hardly longer oblong obovate entire, apex truncate, 

 shortly toothed. Stamen crest ovate rather small, entire. 



"Borneo: Sarawak, Tiang Layu (J. Hewitt). 



"Flowers pale white, lip with some red centrally." Nearest perhaps 

 to G. Curtisii, Bak., but the flowers are much smaller"
