reddish -brown on a pale green ground. Petals shorter than the sepals, 

 lanceolate, acuminate, pale green with purple veins, midrib thickened 

 on the back. Lip shorter than the petals, somewhat deflexed from a 

 concave winged claw attached to the base of the column ; apical portion 

 ovate-acuminate, its sides towards the base erect and with a reflexed 

 erose margin, with no convexity near the apex. Column 1*2 cm. long, 

 stout, curved, narrowed towards the base. Anther 2-celled, cells parallel. 

 Pollinia ovate-oblong, mealy. Ovary (in flower) 1*7 cm. long, its apex 

 with conspicuous grandular projections between the ribs ; stigma with 

 an overlapping irregularly lobulate border. 



Wetsern Himalaya: Tehri-Garhwal, on Nag Tiba, at elevations 

 between 8,000 and 10,000 feet, Gollan (No. 2,062) and Mackinnon's 

 collector (No. 23,000). The original specimens, discovered in 1881 

 by Mr. W. Gollan, after whom I have named this plant, were in too 

 young a condition even for determining the genus. Its nearest ally is 

 A. alpina, King and Pantling, a high -elevation Sikkim species. From 

 the above it differs chiefly in the rhizome not being scaly, the bracts 

 become erect as the flowers open, it has much shorter racemes, the lip 

 is attached to the base of the column and does not form a pouch, 

 the epichyle has no concavity at its apex, the colouring of the flowers 

 is also very different. 



10. Pogonia Mackinnoni Duthie, n. sp. 



Tuber globose, annular and warted, about 1*2 cm. in diameter. 

 Leaf and scape frequently from the same tuber, but not contempora- 

 neous. Leaf about 5 cm. long and broad, cordate at the base, 7-lobed, 

 terninal lobe acute, the others rounded, principal veins termiuatiug at 

 the end of each lobe, with many less conspicuous intermediate ones ; 

 petiole, 2'5 cm. long. Leaves from the flowering tubers much smaller. 

 Scape 1-flowered, about 10 cm. long when in flower, elongatng till 

 fruiting, enclosed by two or three rather loose tubular sheaths. Flower 

 shortly pedicelled, spreading ; bract erect, shorter than the cylindrical 

 truncate ovary. Sepals spreading, linear-lanceolate, acuminate, 1*6 to 1*7 

 cm. long, light green blotched with reddish-brown outside. Petals very 

 similar to the sepals, but a little shorter and not so acute at the apex. 

 Lip shorter than the petals, oblong when spread out, strongly 3-nerved, 

 white tinged with green towards the base ; side-lobes erect, acute ; 

 terminal-lobe blotched with purple. Column slender, 7*8 m. long. 

 Pollinia 2, narrowly clavate, connate below and without a gland. 



Western Himalaya: near Mussoorie, at elevations between 4,500 

 and 6,000 feet, P. W. Machinnon. Flowers during May and June. 



Very similar in habit to P. macroglossa, King and Pantling, but the
