 other terrestrial Orchidese of the Neottia tribe, to some of 

 which, such as Spiranthes grandiflora and Pelexia spi-

As there are several other genera of the Neottia division 

 of Orchideous plants, which are at present only known by 

 name, we avail ourselves of the present opportunity of 

 defining some of those which are the most remarkable, in 

 order that no confusion may be introduced
