The margins of the sheaths are very thin and marcescent, and' are soon 

 lost in the herbarium; they end in the lanceolate blunt ligula-lobes (10 

 mm. long), connected within the sheath by an inconspicuous transverse 

 strip. The inflorescences arise laterally from the nodes of the rhizome, as 

 well from some of the outermost scaled ones as from the leaf-axils. The 

 former are nude only involucrated by appressed brown scales, the latter 

 enclosed within the leafsheaths. They consist of thin short spikes at the 

 top of short (5—10 mm. long) fleshy, branched, brown side-twigs. In the 

 simplest case each sidetwig bears 2 to 4 sessile spikes in a row. 



The spikes are composed of two or three thin greenish white, 5—10 

 mm. long, straight internodes, much flattened and dilated to their top (in 

 a dried state capillary-clavate), forming a flexuose rhachis continuing above 

 the youngest flower into a clavate capillary rudiment, 15 mm. long. 



There are three or four distant primary bracts, erect, appressed to the 

 rachis, not imbricating, only a little longer than the internodes. They are 

 cymbiform, acute, 15—20 mm. long, smooth but covered with rare appressed 

 conspicuous hairs» of a somewhat rigid consistence, mottled pale purple 

 brown. 



The primary bracts embrace one flower each, enveloped by the thin 

 membranous convolute bracteole, little shorter than the bract, (15—18 

 mm.) The calyx is only 5 mm. long, tubular, truncate. The corol 

 tube is 10 times as long, slender and almost not widened at the faux, which 

 is not hairy within. The petals are oblong, obtuse thin, of the same shape, 

 subcucullate, 13X4. The labellum is obovate 20 mm. long, 15 mm. wide 

 above the midle, patent with a broad semilunar crisped foremost portion 

 and deep very concave lower part, which is grandually narrowed at the 

 somewhat villous base and there connected to the staminodes and filament, 

 forming a funnelshaped faux. The staminodes are linear-obcuneate or spa- 

 thulate with a round top, as long as the stamen (13 mm.) and adnate to 

 the lower half of the filament, connecting it with the base of the labellum. 



The stamen is erect, the filament strapshaped 5 mm. long and adnate 

 to the staminodes over 3 mm. The connective is continuous, oblong, pro- 

 longed above the cells into a very small (1 mm. long) rounded crest. The 

 cells are linear, dehiscing longitudinally, 7 mm. long; they are abruptly 

 narrowed at their base into a very small but distinct spurli- 

 ke appendix, formed by the valves, not by the connective. The pollen 

 is aculeate. 



The concave part of the labellum is red purple, with white mottlings, 

 of the same colour are the base of the staminodes and filament. There is 

 a yellow spot in the center of the labellum; the other parts are white.
