It is quite likely that Bumelza lanuginosa, as it is under- 
stood at present is a composite species, but we have not yet 
sufficient material from many parts of the vast area over 
which the plant extends, to warrant segregation. There 
are conspicuous differences exhibited in habit, character and 
quantity of the pubescence, size of the flowers, and leaf-form, 
but as yet I have not been able to correlate these differences 
with distinct specific lines.
