44 J. F. Duthie — Some new species of Orchideae. [No. 1, 



leaves are more distinctly lobed ; the flowers are much smaller, and 

 are spreading, not drooping. Leaves and fruiting scapes are sometimes 

 found on the same tuber. 



11. Hermimum Mackinnoni Duthie, n. sp. 



Whole plant upwards of 22 dm. high. Tubers narrowly oblong. Lower 

 portion of the stem clothed with a few close-fitting tubular subacute 

 sheaths. Leaves two, 12-14 cm. long by 1-2 cm. broad, oblong or linear- 

 lanceolate, acuminate, with loosely amplexicaul tubular bases, 3-5-veined. 

 Spike cylindric, rather broad, about 11 cm. long, many-flowered. Flow- 

 ers, spreading, crowded, about 10 m. across. Floral bract, 5 m. long, 

 broadly lanceolate, acuminate, a little shorter than the ovary. Sepals 

 3-4 m., ovate-oblong, acute, subterete, green. Petals as long as the 

 sepals, linear-lanceolate, divergent, white. Lip trifid, a little longer 

 than the petals, deflexed from near its base, white with a slight tinge 

 of green, margins inflexed, lower portion very thick and with a small 

 concavity at the base ; side-lobes filiform, curved inwards ; midlobe about 

 half as long as the side-lobes, lanceolate, obtuse. Anther-cells, diverg- 

 ing below ; pollinia obovate ; caudicles, very short, the glands discoid, 

 naked ; staminodes large, spreading. Stigmas 2, transversely oblong 

 and lying between the pollinia-glands and the concavity of the lip. 

 Ovary about 6 m. long, ovate-oblong, beaked. 



Western Himalaya: near Mussoorie, at about 6,500 feet, on oak 

 trees, P. W. Mackinnon. Flowers in August. 



A very distinct species, its nearest ally being 3. angustifolitim. 

 It differs from the latter by its fewer much shorter and broader leaves 

 its shorter and broader flowering spike, white petals and lip, and with 

 the mid-lobe of the latter much longer ; the shape of the ovary is also 

 very different. 



12. Habenaria Elisabeths Duthie, n. sp. 



Height of plant up to 4*5 dm. Bulbs ovoid. Leaves 2-3, approxi- 

 mate towards the base of the stem, with a few lanceolate finely acumi- 

 nate sheaths above and a few loose ones below them, 6"12 cm. long and 

 1 to 2 cm. broad, lanceolate, the upper acuminate, the lowest one acute 

 or obtuse, amplexicaul at the base, midrib prominent beneath. Spike 

 long and slender, sometimes up to 2*5 dm. Flowers sessiles, small, green, 

 rather crowded, horizontal or deflexed. Bracts lanceolate, acuminate, 

 about half as long as the ovary. Sepals erect, the dorsal one ovate, con- 

 cave, the lateral ones obliquely ovate. Petals a little longer than the 

 sepals, obliquely ovate, obtuse. Lip 3-cleft, fleshy, longer than the 

 sepals, with a long concave claw ; lateral lobes linear, spreading, gibbons
