ORCHIDACE.E 



conspicuously one-nerved. Dorsal sepal about 4.5 mm. long, 2- 

 2.5 mm. wide, oblong-ovate, acute, strongly concave, dorsally 

 carinate, prominently one-nerved. Petals about 4 mm. long^ 

 1 mm. broad below, linear, obtuse, one-nerved. Lip spurred, di- 

 lated from a distinct claw into a suborbicular blade ; claw about 

 1.5 mm. long, 1.25 mm. broad, mostly occupied by a fleshy longi- 

 tudinal callus ; lamina about 4.7 mm. long, 5 mm. wide, broadly 

 rounded on each side, with a small abruptly triangular obtuse 

 apex (lip might thus be termed three-lobed), sub-fleshy in tex- 

 ture; spur conspicuous, strongly arcuate, in natural position about 

 5 mm. long, cylindric-conic, broad below tapering to a bilobed 

 apex, sulcate on the dorsal and ventral surfaces near the apex, 

 provided within — midway on the anterior wall — with a small 

 longitudinal callus. Column short, stout. Ovary becoming about 

 1 cm. long, cylindric-ellipsoid. 



This species, while showing the general attributes of the genus, 

 is very tall, stouter than usual, and the flower possesses a very 

 long spur. The flowers are very advanced and lack anther and 

 pollinia.
