172 • PEOFE890E LINDLEX*S CONTEIBUTIONS TO 



Hong Kong, the Philippines, and Ceylon, as it is of Indian plains 

 as far as Peshawnr. 



What I believe to be SpirantJies autvmnalis occurs in North- 

 western India, and Bp. australis seems to grow everywhere from 

 Siberia, Peshawnr, and North- Western India generally, the Sun- 

 derbunds, Nilgherries, Ceylon, and Java, to Chiaa, New Holland, 

 and New Zealand. What is more, I think that any one who has 

 examined a long suite of specimens will probably be right in 

 regarding this variable plant as nothing more than our own Sp^ 

 testivalis. 



Similar facts are elicited by a critical examination of the genera 

 Epipactis and CepTialanthera, JE. veratrifolia^ a remarkable Persian 

 species, was found at Peshawur by Major Yicary ; and there can 

 be no doubt that the common Indian species described under the 

 names of consimilis^ macrostachya, herhacea and Dalhonsi^, are 

 only so many states of the well-known European M latifolia. It 

 is equally certain that my CepTialanthera acuminata^ foimd all over 

 Northern India from Mussooree to Bootan, is identical with the 

 European Cephalanthera ensifolia. 





Hlpipogium Omelmi was found in Sirmur by Dr. Thomson. 



Lastly, what is most startling and unexpected, is the discovery 

 by Dr. Hooker, in Sikkim, of a species of the genus Tipularia^ 

 hitherto known only in the United States of America. This plant, 

 although different in some respects from the American form, and 

 distinguished by Prof. Eeichenbach, Jun., is probably nothing 

 more than a form of the original Tipularia itself, which thus 

 appears at once in two points of the globe distant some 12,000 

 miles from each other. 



Pacts of this nature are of the more interest, seeing that the 

 ordinary modes of dispersion by birds, by winds, by waves, by man, 

 would seem to be iuoperative, or at least insufficient to explam 

 such very remarkable ranges. 



In the following enumeration of species, I have not thought it 

 necessary to observe much order, the purpose of a catalogue being 

 equally well served whatever the sequence of the species.
