tory between O.fusca and militaris. So Haller thought. The 

 English botanist will now have materials upon which to found 

 an opinion for himself.

Rather smaller than the last, with which its herbage otherwise 

 accords. The spike and bracteas scarcely differ in the slightest 

 degree from that species, any more than the pale, taper-pointed 

 leaves of the calyx, or the almost linear, purplish petals. The 

 only remarkable distinction is observable in the lip of the nec- 

 tary, which is deeply divided into 4 linear, obtuse, equal and 

 uniform, purplish segments, with a small intermediate point ; 

 all pale or whitish at the base, like the disk of the lip whence 

 they originate, which is downy and dotted. From frequent 

 examination of these plants growing, and not from neglect or 

 inattention, I have, like Linnaeus who studied them at Fon- 

 tainebleau, long concluded them to constitute but one species, 

 the varieties of O. militaris appearing to combine O. tephro- 

 santhos with the very different O.fusca. I am still dubious with
