Dehra Dun near Kajpur, W. Gollan {Dulhic's No. 25404); Garhwál, Fakoncr. In
flower during May. It extends eastwards to Sikkiin, Assam, lUe Khusia Hills and
Upper Burma; it is also found in the Bombay Presidency and in S, India.
The flowers of the Sikkim form are less attraotive than those of the form found in Assam and
00 the Khasia Hills, aad Sir (Jeorge King has reason to believe that this species is usually self-fartile,
aud that it may represeut a stage m the transition towards oleistogamy.

This remarkable plant which,
Hied species, has giv^
anthers in the orchid family. Falconer,
Lindley pointed out, : doubt a peloriate state or variety
allied given rise to much discussion as to the normal position of the supplementary
bis note published iu the Proceedings of the Linnean Society,
vol. i,, p, 14, says:—"In my plant it is most distinctly evident both by a dBCUZTent ridge on eaoh
filament and by transverse sections of the column at all heights down to its base, that the supplementary
anthers have the same relative position as the usual fertile one, and in harmony with Lindley's
formula." It was suggested by Lindley that D. normole might prove to be a monstrous condition of
D. Jimbfiatim, but the inflorescence of the former is more Lke that of 1). chivatum, whilst the leaves
fclmost exactly resemble those of D. chri^smihum.
