the form and structure common to Orchidee, and along the back of each placenta is a dense mass of white 
conducting tissue? formed of delicate white, transparent, mucilaginous tubes. 
Cyrtosia Lindleyana is not uncommon near Dorjilng. None of the seeds I sent to Calcutta or to 
England germinated, nor did the roots which I dug up live, either at Dorjiling or Calcutta. I never could 
trace any parasitic attachment between its roots and those of the other plants with which it grew, nor am I 
aware that a parasitic attachment has been proved to exist in any Orchid. I have also sought in vain for 
such in Listera Nidus-avis. 
The plant is dedicated by Dr. Thomson and myself to our friend Dr. Lindley, who has laboured so 
long and successfully in investigating the structure and affinities of the extremely difficult Natural Order to 
which it belongs, and who has kindly undertaken the determination and description of our Indian species 
for his admirable work the ‘ Folia Orchidacea.’
