ceolate acuminate leaves, is apparently near this ; but the frag- 

 ments of flowers before me afford little information except that 

 the lip is broad with fine hairs on the inside near the edge. 



119. D. spathaceum; caulibus gracilibus erectis, foliis anguste ob- 

 longis apice oblique obtusis, bracteis linearibus membranaceis basi 

 coloratis, sepalis petalisque sequalibus acutis mento brevi rotundato, 

 labelli angusti lanceolati laciniis lateralibus rotundatis medio tuber- 

 culatis ad sinus plicatis intermedia duple longiore acuta. 



Sikkim, at the height of 6000 feet, /. D. H. (143). 



A solitary specimen of this exists in Hooker's herbarium; the 

 stems are about 6 inches long, and the flowers (apparently solitary) 

 the size of those of D. macrostacJiyum. 



120. D. SCABRILINGUE J foliis oblongis apice obtusis valde obliquis, 

 floribus geminatis, sepalis petalisque ovalibus sequahbus, mento 

 conico, labelli 3-lobi medio pluries canahculati lobis lateralibus semi- 

 ovatis obtusis intermedio carnoso oblongo scabro multo brevioribus. 



Borneo, T. Lohh. 



A pair of flowers and a single leaf, communicated by Messrs. 

 Yeitch, are the materials on which this very distinct species is 

 established. Its structure is, however, so peculiar, that no doubt 

 can exist of its perfect distinctness from any other yet known. The 

 flowers appear to be white. The lateral sepals from the point of 

 the mentum to their own apex are about an inch long. 



121. D. TRUNCATUM J caulibus gracilibus ramosis basi ramulorum sub- 

 rotundis incrassatis, fohis linearibus obhque emarginatis, floribus 

 solitariis, sepahs petalisque ovatis acutissimis sequalibus, mento ascen- 

 dente valde obtuso ovario duplo longiore, labelU laciniis lateralibus 

 semicuneatis intermedia lineari basi unidentata. 



Java, Reinwardt, Lohh. 



I find this among Eeinwardt's plants under the name of Ophrys 

 puhescens of Blume ; probably owing to some error in labelling, 

 for there is no such name known to me, nor has this any structure 

 that can be called pubescent. It is a very small-flowered slender 

 species, closely allied to D. tetraedre, from which it differs in the 

 labellum, and in the thickened bases of the branches being round 

 or roundish oblong, not at all angular. 



122. D. INVOLUTUM ; caulibus teretibus, foUis ovato-lanceolatis oblique 

 obtusis, gemmis oppositifoliis conicis, sepalis petalisque lineari-lan- 

 ceolatis sequalibus acuminatis apice incurvis, mento brevi acuto, 

 labelli laciniis lateralibus acutis falcatis intermedia revoluta crispa 

 acuminata brevioribus.
