* The species name is generally spelt with a capital initial, Habenaria 

 being the name of a genus. Linnaeus, however, did not take the trivial 

 name from a generic name, as Habenaria was founded much later by 

 Willdenow (1805). As therefore the species name is not taken from a 

 generic name (see International Rules of Botanical Nomenclature (1905) 

 Rec. x) it should begin with a small letter as in Linnaeus's original 

 description.
