This species, like B. stellato-tomentosa, shows remarkable variation in shape 

 between the leaves on the same stem, and is (as S. Moore states) closely allied thereto. 

 The heads, however, are difTcrcnt from the subglobose heads of -B. stellato-tomentosa, 

 closely enclosed by the viscid coloured imbricated outer ovate floral leaves.
