Cleisostoma cryptochilum. 

 (Sect. Achilum). 



Leaves large, oblong, strapshaped, blunt, unüaterally excised at 

 the summit; racemes glabrous, several from a common stalk, alternate, 

 constituting an ample panicle , each bearing several flowers ; bracts 

 very f3hort, semi-ovate-deltoid ; stalklets about as long as the flowers ; 

 tube of the calyx slender; lobes rosy-red; the three outer oblong- 

 lanceolar , all gradually narrowed at the base and free ; the paired 

 inner lobes ovate-spatular, rather longer than the rest; total labellum 

 (labial lobe) hollow, curved, clubshaped-cylindrical ; the lateral lobules 

 reduced to minute thin auricles somewhat decurrent to the distant 

 very small semilanceolar revolute membranous middle-lobule , the la- 

 bellum thence continued into a spur-like more turgid end, the whole 

 about one-third shorter than the other calyx-lobes ; gynostemium much 

 shorter than the labellum ; the two double pollen-masses ovate-globular, 

 affixed to a proportionately short caudicle. 



In South-eastern New Guinea; Rev. James Chalmers. 



Leaves (transmitted apart) 8—11 inches long, towards the middle 

 nearly an inch broad, only slightly keeled , probably flat when fresh. 

 An only panicle seen about a foot long, spreadingly branched. Bracts 

 soon bent downward. Sepaline and petaline lobes of the calyx 1/2 — '/4 

 of an inch long , five-nerved ; turgidity of the labellum almost ovate, 

 parallel-nerved ; middle lobule about one line long, forming almost an 

 opercular scale slightly above the middle of the whole labellar organ ; 

 no divisional plate within the spur-like portion of the labellum ; fruit- 

 bearing calyx-tube gradually wider towards the summit, but not turgid. 

 Ripe fruit not obtained. 



This species is as handsome as it is structurally remarkable, diftering 



from all other members of the genus in the extreme minuteness or 



almost obliteration of the labellum, and in having the so-called spur 



(or mentum) continuing the labellum itself and not turning into a 



direction opposite to the point of Insertion of the labellum ; the latter 



consists therefore almost entirely of the spur, only its starting portion 



being slit anteriorly , and the middle lobule being homologous to the 



ordinary inner spur-scale of Cleisostoma, its direction in bud being 



also centripetal. The sectional characteristic might almost be raised 



to generic value.]
