J 1. in _An extremely variable species in habit and length of hgule especially, 



ihioh is usually short in Earopeau examples. The form with a long ligule forms a link 

 with P. attenuata, 'I'rin., which has usually a more contracted habit. Most ot the 

 described varieties of nemoralis are also Indian. „ , ■ ,
