128 Gr. King & R. Pantling — New Orchids from Sikkim. [No. 2, 



Sikkim : at Bucheem, elevation 8,000 feet, in flower in November. 

 Dr. T. Anderson No. 1228. 



A little-known species allied to G. cordata, Benth. 



APHYLLORCHIS, Blume. 



Aphtllorchis parviflora, n. spec. Height of entire plant about 

 10 inches, glabrous. Rhizome short with fibrous fascicled rootlets. 

 Stem erect, about "1 in. thick, leafless, but with 4 or 5 sheathing bracts 

 "5 to 2"5 in. long. Raceme about 2 in. long, many-flowered, the rachis 

 stout. Flowers *15 in. across, the labellum superior ; flower bracts 

 lanceolate, shorter than the straight untwisted tumid ovary. Sepals 

 and petals sub-equal, linear, acuminate, spreading, their apices recurved, 

 all keeled externally. Lip ovate with a broad obscurely- lobed base, 

 sub-acute, concave. Column very short, rostellum prominent, anther 

 with reflexed margins. Pollinia 2, the grains loosely cohering. 



Sikkim : In the Lachoong Valley ; at an elevation of 10,000 feet ; 

 flowering time July. Pantling No. 383. 



This has smaller flowers than any Indian species of Aphyllorchis 

 hitherto described. The ovary not having the usual half -twist, the 

 labellum becomes superior. 



CORYSANTHES, R. Brown. 



Cortsanthes himalaica, n. spec. Height of the entire plant 2 or 

 3 inches ; the tuber "25 to *35 in. in diam., depressed-globose, hairy. 

 Stem glabrous, with a single convolute sheath near its base. Leaf 

 solitary, "3 to "5 in. long, sessile just under the flower, concave cordate, 

 acute, sometimes apiculate, green in colour, the midrib and nerves 

 white. Flower solitary, "6 in. long, the bract linear-lanceolate, slightly 

 longer than the thick sessile ovary. Dorsal sepal oblanceolate, blunt, 

 concave, arching over the column and the basal half of the lip ; 

 laterals short, filiform, bifurcate, lying between the two spurs of the 

 lip. Petals none. Lip oblong, longer than the dorsal sepal, deflexed 

 from about the middle ; the basal portion convolute, with 2 short cylin- 

 dric straight spurs; the anterior half with unequally denticulate margins, 

 its apex blunt. Column short, stout ; stigma orbicular ; anther erect. 



Sikkim : At Lamteng in the Lachen Valley, at an elevation of 

 9,000 feet, on a moist vertical rock, in flower in July. Pantling No. 385. 



The dorsal sepal and lip are transparent and have rich dark purple 

 markings. Its nearest ally is Corysanthes fornicata, Blume, a native of 

 high mountains in Java. 



This is a most interesting addition to the British Indian Flora, no 

 species of Corysanthes having hitherto been known to grow farther
