below referre^l 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 poUinia. Moreover, as stated 

 under Sabenaria, 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 Unear-oblong or lanceolate, spike oylindric dense-fld., bracts green 

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

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

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

Wbstbbn Temperate Himaiata ; from Nepal to Kashmir, and in Western 

 Tibet, alt. 8-12,000 ft. (16,000 ft., Seyde.) — Dibteib. 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. Spilse 1-6 in. ; flowers about f in. from dorsal sepal 

 to tip of lip, duU purples 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. indAca 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, JDon. 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 oylindric obtuse. Gymna-

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

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

 forms Spihe 2-4 in., 2-many.fld. ; bracts J-f in., lanceolate, acuminate; flowers 

 i-4 in. diam., white or purple ; lateral sepals oblong-lanceolate, subereot ; 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 

 retusef spur thin-walled, slightly incurved, tip sometimes clavatej anther-cells 

 parallel. 



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

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

 subequallateral suberect, lip obovate not longer than the sepals entire or 

 obscurely 3-lobed, spur shorter than the ovary stout Mook.f. Ic. Plant med.
