ORCHIDACEiE 



of the inflorescence 1.5 mm. or more long, ovate, concave, re- 

 flexed in development. Flower medium-sized for the genus, pel- 

 lucid in the dried specimen. Lateral sepals about 3 mm. long, 

 5 mm. wide, broadly triangular, acute, very oblique, forming a 

 deep saccate mentum, three-nerved. Dorsal sepal about 3 mm. 

 long, 2 mm. broad, ovate, strongly concave, acute, three-nerved. 

 Petals about 2.6 mm. long, 1.3-1.75 mm. broad, oblong or ob- 

 ovate-oblong, broadly rounded and more or less minutely apicu- 

 late at the apex, indistinctly three-nerved. Lip about 6 mm. long, 

 3 mm. wide near the base and a little narrower near the apex, 

 oblong-pandurate, terminating in a pair of rounded lobes, 

 rounded at the base which is provided with a thin hippocrepi- 

 form keel, highest at the base with the parallel arms extending 

 to the anterior portion. Column very short, broadly winged, with 

 a short triangular retuse rostellar process and with a long broad 

 unciform foot. 



This species shows numerous variations. In Clemens 360 occur 

 flower-bearing branches up to 14.5 cm. long having several clus- 

 tered racemes and one solitary raceme about 10cm. long; unnum- 

 bered material shows one floriferous branch more than 27 cm. 

 long. A collection made by Haslam shows several clustered in- 

 florescences, fascicles of fibrous flexuous tomentose roots which 

 are up to 1 mm. thick and flowers apparently somewhat larger. 



The nearest allies of this plant appear to be Appendicula El- 



meri Ames and A. rupicola (Ridl.) Rolfe. The flowers of this 



species are considerably larger than those of the former with 



lip of different form. It is distinguished from A. rupicola by 



the shorter leaves which are broader in proportion and by the 



flowers which are almost twice as large.
