OKCHIDACE^. 513 



quent in Scotland, northern England, and Ireland, less so in southern Eng- 

 land. Fl. summer. 



XIIT. ACERAS. ACEEAS. 



Flowers and habit of an Orchis, except that there is no spur whatever to 

 the lip. 



A genus of very few species, from Europe, Asia, and northern Africa. 



1. Man Acer as. Acer as anthropophora, £r. 



(Ophrt/s, Eng. Bot. t. 29. Man- Orchis.) 

 A rather small species, seldom above 8 or 9 inches high, with entire 

 tubers ; the leaves varying from ovate to oblong or nearly lanceolate. Spike 

 slender, 2 to 4 inches long. Flowers of a duU yellowish-green ; the .sepals 

 converging over the column and petals as in the lizard Orchis, but very 

 much smaller. Lip narrow-linear, twice as long as the sepals, and fanci- 

 fully compared to a hanging man, two lateral lobes representing his arms, 

 and the middle one, which is longer and 2-cleft, his body and legs. 



In dry pastures, in southern Eiu-ope, more sparingly dispersed over west- 

 ern Germany and France. In Britain, only in the eastern coxmties of 

 England. Fl. early summer. 



XIV. HERMINIUIMI. HERMINIUM. 



SmaU-flowered plants, nearly aOied to Orchis, but the perianth has no 

 spur, and the anther-cells are distant at their base, the glands of the stalks 

 of the pollen-masses protruding below the cells. 



A genus of very few species, from the high northern or alpine regions of 

 Europe and Asia. 



1. Musk Herminium. Herminium Monorchis, Br. 



{Ophrys, Eng. Bot. t. 71. Musk Orchis.) 

 A slender plant, seldom above 6 inches high, with 2 or very seldom 3 ob- 

 long or lanceolate, radical leaves. Tubers nearly globular, like those of an 

 Orchis, but the new one, instead of being produced close to the stem, is 

 formed at the end of one of the fibres proceeding from the crown, thus 

 forming a creeping rootstock. Spike slender, with numerous, small, yellow- 

 ish-green flowers. Sepals erect or scarcely spreading, and narrow. Petals 

 narrower and rather longer, instead of being shorter as in most British 

 Orchids. Lip scarcely longer, erect, hoUowed into a kind of pouch at the 

 base, but not spurred, with 3 narrow, entire lobes. 



In hilly pastures, in central, northern, and Arctic Europe and Russian 

 Asia, and in the mountains of southern Europe. Very local in Britain, 

 chiefly in the southern and eastern counties of England, and unknown in 

 Scotland or Ireland. Fl. summer. 



XV. OPHRYS. OPHRYS. 



Habit, tubers, and foliage of an Orchis, but the flowers have no spur, 

 and the Up is usually very convex, resembling more or less the body of
