6. Cymbidium Mackinnoni Duthie, n. sp. 



Terrestrial, casspitose. Pseudo-stem short, emitting many thick 

 spongy roots. Leaves linear, acuminate, 3-4 dm. long and about 1 "3 cm. 

 broad ; margins not serrulate, the lowest ones sheath-like and mem- 

 branous. Scape 1-flowered, much shorter than the leaves, clothed to 

 the base with loose lauceolate acuminate cymbiform hyaline sheaths. 

 Floral bract longer than the much curved ovary, pale yellow with purple 

 veins. Flowers about 5 cm. across, nodding. Sepals and petals 

 spreading, green. Sepals lanceolate, obtuse, a little longer than the 

 petals. Petals elliptic-lanceolate, obtuse, 5-nerved. Lip about as long 

 as the petals, obovate-oblong (when spread out), 3-lobed, saccate at 

 the base, very pale yellow blotched with purple ; lateral lobes 

 narrow, erect ; the terminal one abruptly deflexed, rounded at the 

 apex and nearly entire ; the disk with two raised smooth lamella? ex- 

 tending from the base to a little beyond the side-lobes. Column short, 

 stout, curved, concave in. front, marked with purple blotches like the 

 lip. Pollinia 4, obliquely obovoid, plano-convex, the segments of each 

 pair unequal, attached to a hemispherical gland. Ripe capsule 1/5 dm. 

 long (including the long pedicel), ellipsoid-clavate, prominently 

 ribbed. 



Western Himalaya: near Mussoorie, at an elevation of about 5,500 

 feet, growing under trees; in flower during February, P. W. Mack- 

 innon. 



Mr. Rolfe informs me that its nearest ally is G. virescens, Lindl., a 

 native of Japan. Of Indian species it most nearly resembles G. cyperi- 

 folium in habit. It is, however, a much smaller plant, the scape is always 

 1-flowered, and the colouring of the lip and the shape of the pollinia 

 and gland are very different ; also the margins of the leaves are entire 

 and not serrulate as in G. cyperifolium. The latter is also found in 

 similar localities near Mussoorie, but always at a slightly higher eleva- 

 tion, and it comes into flower several weeks later. 



7. Listera Inayati Duthie, n. sp. 



Whole plant 1'5 to 2 dm. high. Roots fibrous. Stem stout, about 

 as long as the raceme, and bearing 3-6 loosely-fitting, blunt sheaths, the 

 two upper ones sometimes opposite and leaflike. Flowers in dense racemes, 

 4 m. long ; rachis glandular-pubescent. Floral bract ovate or lanceolate- 

 acuminate, a little longer than the stalk of the ovary. Sepals and 

 petals conn i vent ; dorsal sepal oval, concave, about 2 m. long; lateral sepals 

 a little longer than the dorsal, obliquely ovate, tapering to an obtuse 

 apex. Petals about as long as the dorsal sepal, spathulate, subacute.
