ORCHIDACE^ 



suberect, not equaling the petiole, densely white lanate, clothed 

 with sheaths at the base. Ovary about 4 mm. long, slender, 

 densely white lanate. Flower almost 7 mm. long, slightly open, 

 pellucid in the dried specimen. Sepals connate at the base. Lat- 

 eral sepals about 5.5 mm. long, 2-3 mm. wide, lanceolate-oblong, 

 very oblique at the base, the upper margins involute to a cucul- 

 late apex, lower part forming a saccate mentum, three-nerved. 

 Dorsal sepal about 5 mm. long, 2 mm. wide, oblong, broadly 

 rounded at the apex, three-nerved. Petals about 5 mm. long, 

 1.3 mm. broad above the middle, linear-oblanceolate, subacute, 

 one- or indistinctly three-nerved. Lip about 6.2 mm. long, 2.6 

 mm. wide across the anterior part when extended, oblanceolate- 

 oblong in outline, rounded at the apex, the thin and membra- 

 naceous sides ciliolate and involute or revolute, the anterior third 

 very greatly thickened especially through the central axis ; near 

 the base are two short, parallel, callose keels ; three approximate 

 parallel nerves run from the base to the thickened apex. Column 

 abbre\dated, provided above with a pair of spreading oblong, 

 broadly rounded, pellucid arms with involute margins and below 

 with a small unciform foot. Pollinia eight, obliquely ovoid. 



Of the more nearly allied species, Ceratostylis ind'ifferens J. J. 

 Sm. is perhaps nearest to C. crassilingua, but it is much smaller 

 in all its floral parts. C. landfolia Hook. f. appears to be a very 

 close ally, but the lip is quite different. While vegetatively sim- 

 ilar to C. resiana J. J. Sm., C crassilingua has much larger 

 sepals, narrower petals and a larger lip.
