 Baron Fer-dinand von Mueller, K C.M.G., F.R.S., &6., 



GOVEKNMENT BOTANIST OF VICTORIA. 



Stem elongated, slender, with numerous transverse scars, 

 gradually thickened towards the base ; leaves alternate towards 

 the summit of the stem, linear or narrow lanceolar, rather 

 chartaceous than coriaceous, faintly and obliquely excised at 

 the summit ; I'acemes lateral and between the leaves, about as 

 long as these, bearing about five flowers ; bracts much shorter 

 than the pedicels ; lobes of the calyx glabrous, almost mem- 

 branous, cream-colored, the upper lobe ovate-lanceolate, revolute, 

 the lower lobes falcate semi-lanceolate, spirally curled back, 

 twice as long as the oblique-semiovate basal prolongation ; inner 

 lobes (petals) linear -lanceolate, also spirally ticisted, much 

 narrower and somewhat shorter than the outer lobes ; tube of 

 the calyx several times shorter than the lobes; labial lobe 

 (labelluin) glabrous, considerably extended beyond the other 

 calyx lobes, almost membranous, its terminal lobule compara- 

 tively large, renate, pale-yelloivish, strongly bent back at its 

 apiculated upper portion, travei'sed towards the base by seven 

 flabellar spreading faintly papillular elevations ; the lateral 

 lobules very small purple veined, decurrent on the downward 

 slightly dilated basal portion, the axis lined by three narrow 

 prominent sharp ridges ; gynostemium almost truncated. 



South Eastern New Guinea. 



Cultivated in the Garden of the Acclimatisation Society, 

 of Brisbane, and referred to me by F. M. Bailey, F.L.vS., 

 Government Botanist of Queensland. The specimen seen 

 about 2 feet high ; the thickened lower portion of the 

 stem to ^ an inch wide, the upper portion of the stem 

 very much thinner. Leaves 2^-5 inches long, from hardly 

 ^ to nearly 1 inch bi-oad. Flowers inodorous. Bracts 

 1-1| line long. Upper lobe of the calyx measuring J 

 inch in length, lower lobes slight!}' longer; the terminal 

 lobule of the labellum nearly half an inch broad. Pollinia 

 4, connate into two oblique ovate masses, dark-yellow. 



This species might with equal right be inserted either in 

 the section Stachyobium or Eudendrobium. Among congeners 

 it could systematically best be placed near D. Johannis.
