of Sect. Peristylus, to which this species is perhaps referable, but the branched 
rootstock, habit, and habitat induce me to refer it here. 
** No stigmatic processes. 
74. H.arcuata, Hook. f.; stem very robust leafy, leaves oblong or 
lanceolate, bracts herbaceous narrow longer than the large flowers, dorsal 
sepal beaked, petals small linear membranous, lip twice as long as the 
sepals linear, spur many times longer than the ovary. Platanthera ar- 
cuata, Lindl. Gen. & Sp. Orchid. 989. 
WzsrERN HIMALAYA; Royle; Naini Tal, Davidson. 
Stem as thick as the little finger. Leaves 3-4 in., oblong, subacute, upper 
lanceolate, bases sheathing. Spike many-fld. ; lower bracts 1-14 in., linear-lanceolate ; 
ovary 12 in., hardly beaked, curved ; sepals 4 in. lcng, dorsal cucullate, lateral larger , 
oblong, obtuse, 3-nerved, deflexed ; petals very narrow, l-nerved; lip large, linea z 
with rounded shoulders at the bise, puberulous, sides reflexed, spur 2-23 in., in- 
curved, acute; anther large, broad, cells divergent, tubes erect; pollinia with stout, 
short caudicles, glands very large, ovate; rostellum broad, flat, acute.—A very 
remarkable species, with the lip of Hologlossa, but anther of the larger Trimero- 
glosse. I have seen but one specimen from Col. Davidson, and a rude tracing in 
Herb. Lindl., of Royle's plant. 
75. H. sikkimensis, Hook. f.; stem stout leafy, spike elongate lax- 
» bracts herbaceous longer than the large flowers, petals aslarge as the 
Sepals triangular-lanceolate, lip as long as the sepals linear, spur ratber 
onger than the ovary very stout obtuse strongly incurved.
