Orchis. ~] CXLVIIT. ORCHIDS^. (J. D. Hooker.) 127 



below referred to Orchis are referable to that genus. This is owing to my inability to 

 determine satisfactorily in specimens that have been pressed, the structure of the 

 minute rostellum, and its relation to the glands of the pollinia. Moreover, as stated 

 under Habenaria, I have in various minute flowered species of that genus been 

 unable to determine whether the glands are hidden between folds of the rostellum, 

 or are covered by pouches or a flap of that organ. Careful drawings of the column 

 and anther, and a comparative study of the extra Indian species are wanted, in order 

 to describe them with accuracy. 



1. O.' latifolia, Linn. Sp. PL 1334; tubers palmate, leaves erect 

 oblong linear-oblong or lanceolate, spike cylindric dense-fld., bracts green 

 acuminate usually much exceeding the flowers, lateral sepals ovate reflexed, 

 lip oblong or rhomboid crenate entire or very obtusely 3-lobed sides de- 

 flexed, spur stout equalling or shorter than the ovary pendulous. Boiss.

WESTERN TEMPERATE HIMALAYA ; from Nepal to Kashmir, and in WESTERN 

 TIBET, alt. 8-12,000 ft. (16,000 ft., Heyde.) DISTRIB. Westward from Afghanistan 

 to N. Africa and the Atlantic, N. Asia. 



Stem 1-3 ft., usually fistular, leafy upward. Leaves many, 2-6 in., often spotted 

 in Europe, tip flat or concave. Spike 1-6 in. ; flowers about f in. from dorsal sepal 

 to tip of lip, dull purple; sepals and petals acute or obtuse; lip spotted with darker 

 purple, midlobe small or obsolete; spur straight or curved. The Himalayan speci- 

 mens have, as far as I can make out from dried specimens, the leaves unspotted and 

 tips' concave, and are therefore referable to the European var. incarnata (0 . incarnata, 

 Linn.}. Lindley's var. indica is characterized as Having larger flowers, a rounded 

 sub-lobed lip shorter than the spur, which is as long as the ovary. Lindley is dis- 

 posed to refer some of the specimens from N.-W. India to 0. maculata, but the lip 

 in these is not lobed as in the European plant. 0. latifolia is as variable in India as 

 in Europe, from slender to very robust, with a lax or dense-fld. spike, and bracts 

 equalling to or much longer than the flowers. 



2. O. Chusua, Don. Prodr. 23 ; leaves few linear or linear-lanceolate 

 acute, spike very short, bracts longer than the ovaries green, lateral sepals 

 reflexed, dorsal 'much smaller orbicular, lip longer than the sepals broadly 

 obovate 3-lobed, spur as long as the ovary stout cylindric obtuse. Gymna- 

 deria Chusua, Lindl in Wall. Cat. 7058 ; Gen. & Sp. Orchid. 280. G. 

 puberula, Lindl. in Wall Cat. 7059. 



ALPINE HIMALAYA j alt. 10-13,000 ft., Kumaon, DutUe ; Nepal, Wallich. 

 SIKKIM, J. D. H. t &c. 



Very variable in height and stoutness, 3-18 in., flexuous. Tubers oblong, 

 entire. Leaves 1-3, rarely more, 3-6 by f in., almost filiform in very alpine 

 forms. Spike 2-4 in., 2-inany-fld. ; bracts -f in., lanceolate, acuminate; flowers 

 ^ f in. diam., white or purple ; lateral sepals oblong-lanceolate, suberect ; petals 

 shorter, spreading, oblong, obtuse ; lip variable in breadth, often broader than long, 

 lobes spreading, broad, rounded, erose or crenate, rarely oblong with the midlobe 

 retuse ; spur thin-walled, slightly incurved, tip sometimes clavate ; anther-cells 

 parallel. 



3. O. spathulata, Reichl. f. mss. ; leaf solitary radical elliptic, 

 spike few-fld., bracts much larger than the flower, sheaths leafy, sepals 

 subequal lateral suberect, lip obovate not longer than the sepals entire or 

 obscurely 3-lobed, spur shorter than the ovary stout. Hoolc.f. Ic. Plant, ined.
