ORCHIDACE^ 



scarious bracts that become fibrous. Perianth pellucid in the 

 dried specimen. Lateral sepals about 3.5 mm. long, 3.6 mm. 

 wide at the base, ovate- triangular, obtuse or subacute, strongly 

 obliquely falcate, three-nerved, forming a deeply saccate mentum 

 with the column foot. Dorsal sepal about 3.6 mm. long, 1.45 mm. 

 broad, lanceolate, acuminate, slightly thicker near the apex, some- 

 what concave, three-nerved. Petals about 3 mm. long, 1.6 mm. 

 broad above the middle, linear, acute or obtuse, falcate, one- 

 nerved. Lip about 4 mm. long, 4 mm. wide at the apex, simple, 

 flabellate, gently decurved in the middle with the lateral mar- 

 gins upcurving, very broadly truncate at the apex, in the middle 

 of the apical margin abruptly narrowly and deeply emarginate 

 and minutely apiculate, margins at the apex minutely erose, lip 

 above papillose. Column very short and stout, provided with a 

 broad wing which is emarginate with a slender apicule in the 

 center ; column foot broad, deeply saccate, upcurving. Anther 

 triangular-prismatic. Pollinia semi-ellipsoid. 



This plant is easily distinguished from Dendrobium cuneila- 

 brum J. J. Sm. and D. inconcinnum Ridl. by its much smaller 

 size and very different leaves. 



The minute flower with its simple, flabelliform, truncate lip 



makes this species unique. A specimen with somewhat smaller 



flowers than the type is shown by another collection, Clemens 



403. (Plate 91.)
