This species varies greatly in the colour of the corolla and the hairiness of the 

 stem and calyx, but these characters cannot be grouped in such a manner as to form 

 satisfactory varieties. According to Meller the leaves yield an " oily secretion on 

 beiiio- rubbed or pressed, which is insipid and without odour."
