Finally, we may refer to the genus 

 Herminium. There are eight species 

 in Europe and Asia, of which one, H. 

 monorchis (Fig. 2038) (Musk Orchid), is 

 found in Britain. The flowers of this 

 species are small and yellowish-green 

 in colour, with a strong scent of nectar, 

 and are adapted for pollination by 

 very small flies (see p. 1350). 



The genus Aceras has only one 

 species, A. anthropophorum (Man 

 Orchid) (Fig. 2039) which is widely ^ 

 distributed in Europe, especially in 1 

 the Mediterranean region. It is found j 

 locally on the Chalk in Britain.
