Variable, especially in length of spur; in most plants this is 2-3-5 mm, but in some it is 5-8 mm. The long-spurred variants have been distinguished as P. azorica Schlechter, loc. cit. (1920) (Habenaria longibracteata Höchst.), but as variation in other characters shows little correlation and as there is no clear geographical or ecological separation, they are best treated as a variety of 3.
