This fpecies of Orchis has obtained the name of bifolia, on account of its radical leaves being ufually two in 
number and placed oppofite to each other ; but this charader is not perfectly to be relied on, as three are 
frequently met with, nor are thofe radical leaves fo ftriftly oppofite to each other as fome authors have 
reprefented them, or as they are in the Opbrys ovata; the Englilh name of Butterfly Orchis is fcarcely warranted 
by the appearance of the flowers. . . ... . , 
If not To common an Orchis as fome, it is much more fo than Others, being found generally throughout the 
kingdom in woods, pallures, and heaths, efpecially in foils fomewhat ftiff and moill ; in the firlt of thele 
fituations it is by far the moll luxuriant, in the latter it is frequently fo dwarfifh as to be regarded as a variety; 
the lip of the neftary is alfo found to vary confiderably in length in different fpecimens 
It is obvioufly diftinguifhed from others'of the genus by the colour of its bloffoms, the extreme length of its 
lour the delicious fragrance of its flowers, diffufed moll in the morning and evening, and which may vie with 
that of the honeyfuckle- but, above all, by the unufual ftruatire of its flowers : below the ftigma (remarkably 
well defined in this fpecies) there is a circular foramen, jig. 2. between the cavities containing ; 
juft above the ftigma, "is a very confpicuous ridge, M 3. the cafes containing the flamma are placed widely 
'didant from eacK other, and foon change to a brown* hue ; the flamma are very Ioofely placed within them 
and drawn out with the (lighted touch 1 the anthers are club-ffiaped, and divided as in mod others ; the gland 
at the bafeofthe filament is of a circular form, with a cavity on its inner fide Jig. 7. and a kind of jomt-like 
projection on its outer part, Jig. 6 . difficult to deferibe ;-taken altogether, this part is wonderfully curious, 
Thif fylnL°h Mtfoffifficult of culture as many others; and, as its roots are large, it appears to be as well 
calculated for the formation of falep as any other.
