Yes it is similar or they are similar to each other,  B. leptophylla is
normally yellow although can be pale brown to purple and the leaves are
very narrow and long 40-100 mm long by 1-1.5 mm wide and the shrub gets
to about 2 metres tall by 3 wide although that would be the exception,
I've only ever seen them around a metre  by a metre. Another related
spp. is B. telmatiaea which has shorter leaves and cyclindrical rather
than spherical flowers.

	From the ERIN data maps it looks to be a native of the
Fitzgerald River National park and since it was named in 1964 by Gardner
its relatively recent.  But no I don't know the actual plant.
	For anyone who is interested the ERIN site has a fantastic
mapping facility for Australian Plants
	Type in the genus and species of the plant and it produces a
very good map, or a text output with the collection site details, the
address is   http://www.erin.gov.au/database/TAX990R.html

	I'm not sure about extra water, but when a plant grows extremely
well but never flowers outside of its native  range it could be any
number of environmental constraints or conditions that are not being met
to fullfill the species requirements to flower.  On the other hand it
may be that it is far to happy and "unstressed" and sees absolutely no
need to flower!  Maybe a little less attention is called for...  
	My kinda plants :-)
