127. D. ATTENUATUM ; foliis Unearibus gramlaeis i)atentissimis, flo- 

 ribus solitariis squamulis minutis obtusis, sepalis petalisqiie obtusi- 

 usculis, mento linear! obtuso, labelli elongati spathulati lobis lateralibus 

 dentiformibus intermedio subrotimdo margine carnoso medio sub- 

 aspero tubereulis geminis linearibus. 



Borneo, T. Lobb. 



Flowers small, apparently white. Leaves long, narrow, and 

 grassy. Stems slender, ascending, from 6 to 8 inches high. 



*if/^ The only other species of this section are Z). calcaratum (Bot. 

 Beg. 1840, misc. 218) and D. nutans (G-en. & Sp. Orch. No. 73), 

 whose lip is not undivided as it was supposed to be, but lanceolate 

 with short entire lateral lobes and a crisp, almost linear, middle 

 part, as I learn from specimens communicated by my learned cor- 

 respondent Mr. Thwaites (156). 



§ VIII. Pedilonum, Blume. 



No continental species of this section have been observed, nor 

 have I found among the collections examined by me anything like 

 Roxburgh's D. purpureum, a Molucca plant. The following are 

 new insular species. 



128. D. AUROROSEUM {Rchb. f. in litt.); foliis angustis ovato-lan- 

 ceolatis acutis, sepalis petalisque aequilongis acutis, mento elongato 

 obtusissimo, labello nudo oblongo apice dilatato retuso utrinque 

 reflexo ungue unituberculato. 



Java, T. Lobb; Zollinger (231). 



The oval lip, suddenly expanded into a broad apex reflexed on 

 each side, and the extremely broad mentum, are like nothing else- 

 where in this section. The flowers are the size of D. Fierardi. 



129. D. BURSIGERUM J foliis oblongis acutis, spicis cylindraceis densi- 

 floris, sepalis petalisque acutis, mento arcuato infra apicem ventricoso, 

 labello spathulato acuto cucullato. 



Philippines, Cuming. 



Like D. secundum, but flowers are not half the size, and in 

 longer, slenderer, not secund spikes. Lip apparently white with 

 an orange-yellow tip. 



130. D. Reinwardti ; foliis anguste oblongis obtusis apiculatis, spicis 

 densissimis brevibus, bracteis setaceis divaricatis, sepalis acutis, petalis 

 obtusiusculis, mento duplo longiore apiculato, labello nudo angusto 

 spathulato obtusiusculo. 



Banda, Reinwardt.
