Androcalva rossii (brush kurrajong, blackfellows' hemp)

Vulnerable in Vic.

From the scholarly published botanical revision, 
the distinguishing features' wording, 
to check for with magnification (a hand lens in the field or a binocular microscope back inside),
here : 
Wilkins, C. F. and B. A. Whitlock (2011) 
A new Australian genus, Androcalva, separated from Commersonia (Malvaceae s.l. or Byttneriaceae). 
Australian Systematic Botany 24 (5) : 284–349.
—botanical key quotation: 
"
37   Stem and flowering stems with white, stellate hairs, or white with tan centres, ~0.5 mm long  
 –  Androcalva fraseri (SE Qld; North Coast of NSW)

37   Stem and flowering stems with long golden to ferruginous stellate hairs, ~1 mm long  
 –  Androcalva rossii (S NSW; Vic: E Gippsland)
" .

For more than 15 years, I, Jason Stewart, have talked with so many people including great field botanists, 
confused by these two species' distinguishing features. I'm not better. I carefully check the plants' stems everytime.

For clarifying and resolving this confusion, going back to the most recent scholarly evidences–based source for the distinguishing features, 
has the utmost importance (as i have reproduced above) .

• Androcalva fraseri : stems and flowering stems have many white stellate individual hairs (shorter: at 1⁄2 mm average)
(rather than referring to a leaves' undersides' overview of a white appearance or a rusty appearance, which they may have from many other types of hairs there, as that does not have relevance to the distinguishing features between these two species.).

• Androcalva rossii : stems and flowering stems have many long golden to ferruginous stellate hairs (longer: at 1 mm average)
(leaves' undersides' overview often has a white appearance or a golden appearance or even a rusty coloured appearance from many other types of hairs there, yet that does not have relevance to the distinguishing features between these two species. ) .
