Comes near to Banksıa serrata, but differs by a shrubby 
instead of an arboreous stature, by a more deeply indent- 
ed foliage, silky furred corollas, and essentially by a capi- 
tate unfurrowed bright smooth stigma twice as big round 
as the fourcornered tip of the style. Serrata, besides being 
a tree, has a cylindrical furrowed stigma with a thickened 
slanted base, and a style pulvereously pubescent at the bot- 
tom. The flowerheads of the two differ considerably in 
colour: in @mula they are of a yellowish green, in serrata 
of a blueish grey. 
Thirty-one species have been distinguished by Mr. Brown, 
all of them either trees or shrubs of Australia, the former 
however of no considerable height. The genus is divided 
into two sections, of which our plant belongs to the first, 
consisting of the more genuine species; characterized by 
a style of greater length than the corolla, from one side of 
which it protrudes by an arch sprung between the claws 
(ungues) of the petals which open earlier than the blades 
(lamine); by a stigma enclosed within the subsequently 
opening blades of the petals; by a flowering catkin (amen- 
tum) of a subcylindrical form, and a fruiting one of several 
transversely disposed woody one-valved seedvessels (folli- 
culi). The section includes all but one species.
