E. laevis is distinguished from E. melanoxylon by the smooth, ovoid to cylindrical fruits 
with less or non-exserted valves, and the shorter, obtuse calyptra. 
A medium to large woodland tree of 'morrel' habit, occurring on heavy calcareous 
loams in more or less flat country, often associated with E. flocktoniae (Maiden) 
Maiden, E. lesouefii Maiden and a range of other woodland species. Widespread and 
relatively abundant between Norseman and Balladonia (Fig. 7). 
Conservation status: not considered to be at risk. 
The specific epithet is from laevis, a variant, commonly used in botanical Latin, of the 
classical levis, 'smooth'. It refers to the smooth calyptra.
