ORCHIDACEiE 



and ovaries smooth, slender, up to 8 mm. long. Lateral sepals ob- 

 long, subfalcate, obtuse, 3 mm. long, up to 1.5 mm. wide. Upper 

 sepal elliptic-oblong, slightly concave, obtuse, 2.5 mm. long. 

 Petals oblong, at the apex attenuated, scarcely acute, about 2 

 mm. long, 1 mm. wide. Labellum calcarate, three-lobed, middle 

 lobe triangular at base with a jointed, fleshy, narrowly triangular, 

 setaceously bifid appendage. Lateral lobes linear, longer than the 

 gynostemium, erect, obtuse, about 2 mm. long, hardly „5 mm. 

 wide. Spur about 3 mm. long, near the mouth constricted, pro- 

 vided with a small fleshy callus on the posterior wall beneath 

 the column, the tip inflated. Gynostemium fleshy, in front at the 

 apex two- winged, the wings quadrate. Pollinia two. 



In Paxton's Magazine of Botany (6 : 262) Saccolabium bifi- 

 dum is referred to in a brief note. Its habit is said to resemble 

 that of some species of Notylia, " the manner in which the flowers 

 are produced, their structure, and exceeding minuteness, being 

 so far as a hasty glance can determine, in complete accord- 

 ance with the members of that genus." Sarcanthus bifidus, of 

 course, has terete stems and is in structure extremely unlike 

 any Notylia species, but to one who knows the characteristics 

 of Notylia the above description in Paxton's Magazine is worth 

 many words of technical description to call to mind the aspect 

 of S. bifidus. 



The labellum is not unlike that of Sarcanthus javanicus J. J. 

 Smith, but the side lobes are oblong and equal the column in 

 length, and the column appears to be different. There is no sep- 

 tum in the spur. The affinities of this species are surely with Sar- 

 canthus, but the structure of the column is that of Robiquetia as 

 I understand that genus. Undoubtedly there will be much more 

 confusion in the group to which this species belongs before mat- 

 ters are simplified, but at the present time the limits of such genera
