ORCHIDACE^ 



Inflorescences 2.5-3.4 cm. long, rather numerous, entirely lat- 

 eral, rising from about the middle of the leaf sheaths. Peduncle 

 clothed at the base with several closely imbricating, scarious 

 sheaths. Rachis very strongly zigzag. Bracts about 1.4 cm. long, 

 6 mm. wide, distichous, lance-attenuate, cymbiform, widely 

 spreading, scarious, rigid-nervose, carinate, surpassing the ovary. 

 Flower very similar to that of Appendicula longirostrata A. & S., 

 but slightly larger. Lateral sepals about 5 mm. long, 4.5 mm. 

 broad, triangular, oblique, acuminate to a complicate-mucronate 

 apex, forming a very deeply saccate mentum, three-nerved, 

 carinate. Dorsal sepal about 4.5 mm. long, 3 mm. wide at the 

 base, narrowly triangular-lanceolate, acuminate, concave, three- 

 nerved, carinate. Petals about 4.2 mm. long and 1.65 mm. broad 

 at the base, linear-lanceolate, more or less acute at the oblique 

 apex. Lip in natural position spatulate, parallel to the column, 

 the saccate-conduplicate lower portion or hypochil abruptly di- 

 lated into the reflexed terminal portion or epichil ; lamina when 

 expanded about 5 mm. long, 3 mm. broad ; claw short decurved ; 

 hypochil when spread out suborbicular, contracted at the base by 

 the formation of a deep conical sac, the anterior margins termi- 

 nating in the middle of the epichil ; middle lobe or epichil trans- 

 versely oval, retuse and bluntly apiculate. Column very short, 

 provided above with a conspicuous rostellum about 2.15 mm. 

 long, which is abruptly narrowed from a broad base to a narrow 

 bidentate beak. Foot long, stout, U-shaped. 



Clemens 351 has much smaller leaves. Unnumbered material 

 shows leaves up to 13 cm. long and the basal portion of the plant 

 with a cluster of numerous, fibrous, flexuous, rigid roots that are 

 about 1.5 mm. thick. 



There is a surprising similarity of flower structure between 

 this plant and Appendicula longirostrata A. k, S., but the vege-
