1896.] G. King & R. Pantling— 2Vez(? Orchids from Silihim. 125 



beneath which again are two flat converging calli. Gland embraced by 

 the united bases of the caudicles; poUinia flattened curved, oblong, 

 sub-equal in length. 



SiKKiM : at 3,000 to 5,000 feet elevation, not uncommon; flowering 

 in September. Pantling No. 285. 



The sepals are olive green and white ; the lip is white, the teeth 

 of the claw being green, as are also the column and spur. 



This differs from A. Boxburghii (which it resembles in leaves) in its 

 smaller flowers, differently shaped petals and pollinia, also in the ter- 

 minal lobes of the lip and in the teeth of the claw which in this are 

 much smaller. Its nearest ally is however A. Griffithii, Hook, fil., a 

 species of the Naga Hills, which has green leaves without reticulations 

 and a more distinctly winged claw with larger teeth and a longer spur. 



ODONTOCHILUS, Blume. 



Odontochilus tortus, n. spec. Whole plant 6 or 7 in. high. Stem 

 decumbent at the base, stout, bearing 4 or 5 leaves, glabrous. Leaves 

 green in colour, 3-nerved, ovate to ovate-lanceolate, acute, slightly 

 oblique, narrowed at the base into the channelled sheathing petiole ; 

 length about 2 in., breadth "75 to 1 in., petiole "75 in. Peduncle of the 

 raceme pubescent and bearing a solitary acuminate pubescent bract. 

 Raceme about 1'5 in. long, 3- to 6-flowered ; floral bract lanceolate, acu- 

 minate, thinly pubescent, equalling the ovary. Flowers '75 in. long. 

 Dorsal sepal broadly ovate, concave, forming with the petals a hood over 

 the column ; the laterals oblong, blunt and spreading, all pubescent 

 outside. Petals falcately rhomboid, sub-acuminate, mottled with pale 

 green. Lip with a short sub-globose saccate base, a long toothed claw, 

 and a much twisted limb deeply divided into two sub-quadrate slightly 

 divergent irregularly crenate end-lobes the upper margins of which are 

 connivent, the sac containing two approximate stout up-turned teeth ; 

 the claw with nine unequal teeth on each margin. Column with two 

 small approximate up- turned teeth below the entire stigma ; arms of 

 the rostellum large, winged, bidentate. Pollinia in sub-equal pairs, 

 united midway into a pseudo-caudicle ; the gland small, ovate, lateral. 



Bhotan : at Kumai near the Jaldaca river, elevation about 4,000 

 feet ; flowering in December. Pantling No. 354. 



The nearest ally of this species is undoubtedly, 0. Elwesii, Clarke ; 

 but that species has very dark purple leaves smaller than those of this 

 and thicker in texture. O. Elwesii besides has a longer more pubes- 

 cent scape than this, and it never bears more than three flowers. 

 Moreover the lip of 0. Elwesii is not twisted, and its claw has only 

 seven pairs of teeth, while the sac of the lip is bilobed and the column 

 has large processes.
