identical with O. papilionacea; Sprengel asserts, that the 
figure in the Icones is a mere error, arising from its having 
been copied from a wretched drawing. But M. de Can- 
dolle, in his More Francaise, entertains a different opinion, 
and distinguishes OQ. rubra, that is to say, the Piedmontese 
plant described by Allioni under that name, by its smaller 
labellum, which is very slightly crenulated, and neither 
truncate nor emarginate at its apex. We have specimens 
called O. rubra from Granddidier’s Herbarium, which 
answer to this statement; but they are otherwise so similar 
to our O. papilionacea from Naples, that we do not think 
it advisable to distinguish them even as varieties. 
Roots fleshy, undivided. Leaves short, oblong-ensiform, 
spreading, obtuse. Stem erect, a foot high, or something 
less, with membranous venous sheaths, which are greenish 
at the apex. Spike 5-7-flowered. Bractee membranous, 
dilated, pink, venous, longer than the ovarium. Sepals 
reddish purple, venous, ascending; the lower ones some- 
what falcate backwards. “Labellum pale purple, oblong, 
obtuse, undivided, somewhat undulated, crenulate; spur 
thick, conical, straight, somewhat acute, shorter than the 
ovarium.
