This section is made up of four species evidently closely allied, 

 and C. benghalensis (nov. sp.) which perhaps should not be placed 

 here, and differs a good deal. The two common plants C. pilosus 

 and C. procerus (here treated as conglomerate species) have each 

 a very great range in habit and development, and yet are very 

 difficult to separate from each other.
