А very distinct species by reason of the small leaves with flabellate 
nervation and the close silvery tomentum. 
N. E. Brown reduces this genus to OrtAosiphon, as he finds the degree of

base. [t has been thought advisable to leave the nomenclature as above until 
this point has been thoroughly elucidated.
