Subsp. melanobasis is distinguished from subsp. fraseri by the larger, sessile fruits on 
shorter peduncles, the constricted calyptra, the larger, leathery leaves and the 
distinctive stocking of hard, rough black bark. 
Distributed for a few kilometres along Highway One on the eastern slopes and crest 
of the Fraser Range, and probably extending north and south along the range (Fig. 18). 
This distribution lies to the west of that of subsp. fraseri, and also appears to be 
restricted to outcrops of basic metamorphic rocks. 
This taxon is locally dominant on calcareous red loam over basic metamorphic rocks, 
usually in association with E. optima L.A.S. Johnson & K.D. Hill and E. laevis. 
Conservation status: restricted to a small area, although not at risk within this area 
(2R). 
The epithet is from the Greek ttielas, melanos, dark, and basis, base, in reference to the 
characteristic stocking of black persistent bark.
