O. caule fimplici, corolla inflata; labio inferiore breviflimo laciniis

I can meet with no fynonyms for this fpecies. It has a taller and 

 more {lender ftem than O. major, and is upon the whole lefs pubef- 

 cent. The bracteae are fhorter than the flower. Corolla the fize 

 of O. major 1 but the upper lip is of a dark or purplifh colour, and 

 lefs fimbriated or crifped than in that fpecies. The lower lip is re- 

 markably fhorr, in three obcordate fimbriated fegments, of which 

 the middle one is larger than the other two, and is connected at its 

 bafe with the very prominent two-lobed palate of the flower. The 

 ftamina are {lender, thinly clothed all over, as well as the flyle, 

 with fcattered hairs, and project out of the mouth of the flower. 

 The germen is fmooth. I do not recollect its having, when frelh, 

 peculiar fmell. 



The O. gracilis has moft affinity to the minor in fome of its cha- 

 racters ; but differs in its larger inflated corolla, fhort lower lip* 

 longer ftamina and hairy ftyle.
