Shaded forests in the Sikkim Himalaya, alt. 3-5000 ft., J. JD.M. 



A large ramous species, nearest allied to I. Icevigata in foliage and habit, but dif- 

 fering in the long very stout peduncled racemes, 3-7 in. long, smaller bracts, larger pink 

 flowers 2-24 i"- 'ong, with bright rose-coloured spur and standard ; in the red (not 

 green) sepals and more saccate lip. — As in I. Jvirpia and other species the standard 

 varies in being spurred or only gibbous at the back.
