This plant seems to have an unusually extensive geo- 

 graphical range for an Orchis. Bertoloni found it in Provence 

 and Liguria; Cambessedes gathered it on the Puig-di- 



* So called by Dr. Brown, from a., priv., and xsgas, a horn ; in allusion to 

 the prima facie difference between the original species and Orchis. After- 

 wards Richard altered it to Loroglossum, because one of the species was 

 found to have a horn. Then Professor Sprengel changed the name to 

 Himantoglossum, because he did not like Loroglossum. Finally, we retain 

 Dr. Brown's name, because it was the first, and is as good as the others, and 

 because we do not approve of these idle changes.
