ORCHIDACE^ 



cylindric, moiiophyllous, at intervals of 7-9 mm. Leaf about 

 7.5-8.5 cm. long (rarely 5 cm. long), 8-9 mm. wide, linear, obtuse 

 or subacute, sometimes somewhat complicate at the apex, con- 

 tracted into a petioled base, thick and coriaceous, rigid, many- 

 nerved with the mid-nerve more or less sulcate above and cari- 

 nate beneath. Petiole about 3.2 cm. long, slender, sulcate. Scape 

 approximate to the pseudobulb, in course of development sur- 

 passing the leaf, about 14-16 cm. tall, slender, striate in the dried 

 specimen, provided with about four loose tubular membrana- 

 ceous sheaths which are imbricating below and free above. 

 Raceme loose in development. Rachis up to 8 cm. long. Bracts 

 of the inflorescence about 3-4.5 mm. long, narrowly lanceolate, 

 spreading, sui-passing the pedicellate ovary. Flowers very small. 

 Lateral sepals about 3-4 mm. long, 2 mm. broad, triangular- 

 lanceolate, falcate, oblique, forming a saccate mentum, compli- 

 cate-mucronate at the apex, one- or indistinctly three-nerved. 

 Dorsal sepal about 2.5-3 mm. long, 1.1-1.5 mm. wide, oblong, 

 complicate-mucronate, strongly concave, one-nerved. Petals 

 about 1.75 mm. long, .5 mm. broad above the middle, oblanceo- 

 late-oblong, obtuse or rarely subacute, prominently one-nerved. 

 Lip in natural position strongly decurved below the middle, 

 the lower portion membranaceous with erect conduplicate sides, 

 the anterior half forming a sub-fleshy broadly elliptic epichil 

 with revolute margins; limb when expanded about 2.5 mm. long, 

 1.5 mm. broad near the base, ovate-Ungulate, obtuse, appearing 

 subtrilobed, three-nerved. Column minute, provided with a pair 

 of parallel triangular-lanceolate acuminate arms and an unciform 

 foot. 



This plant most closely resembles Bidbophyllum Gibbsiae 

 Rolfe and B. Unearifoliiun King and Pantl. It is distinguished 

 from the former by the uniformly broader coriaceous leaves and
