agree in the arrangement." (Woolls* "Lectures on the Vegetable Kingdom," 
p. 219.) The Lignum Vitae from the banks of the Nepcan (E. Baiieriana} is 
certainly very different from E. polyanthcmos ; it is not at all like E. Daicsoni, 
which is not referred to, directly or indirectly. 
Now let us turn to the bark. 

The original description, which, by the way, refers to a tree in the Bathurst 
district, simply says " arborea glauco-virens " a greenish glaucous tree. Bentham 
(B.F1. iii, 213), however, quotes Mueller. "An ash-grey persistent rough and 
furrowed bark." Mueller, in his " Key to the System of Victorian Plants," 237, 
gives the bark as " rough, persistent." 
Both these descriptions are true as regards the Victorian tree, but, as one 
proceeds northward (making proper allowance for geographical elevation and 
depression) it may be stated in general terms that the trunk tends to get less rough 
till at length it is often flaky and sometimes nearly smooth. 
I attach no undue importance to bark variation. Amongst Box-barks, which 
yary from rough butts to smooth, E. microtheca F.v.M. and E. mclliodora 
A. Cunn., arc notorious examples, and every field-botanist who has given much 
attention to Eucalyptus knows that barks in the same species may vary so much 
that he is quite prepared to accept considerable variation as almost a matter of 
course. 
Coming to the inflorescence and fruits, it seems to me that the only botanical 
differences between E. Dawsoni and E. polyanlhcmos are as follow : 
In E. Dawsoni the fruits are smaller (of less diameter), and have the tips 
of the valves almost flush with the top ; they may even slightly protrude. In 
E. polyanthemos the tips of the valves are deeply sunk. 
The anthers are strictly truncate and terminal in E. Dawsoni, the pores seem 
to open a little lower down in E. polyanthemos , and the anthers are perhaps of a 
different shape. 
In addition, we have such differences in foliage, bark and habit as we think 
we can define. 
Leaves. The leaves of E. polyanlhcmos are normally oval to nearly circular, 
but they may be lanceolate of various widths. The foliage is usually glaucous. 
In E. Dawsoni the adult foliage is usually lanceolate, sometimes oval, sucker 
foliage larger, sometimes orbicular, more so than in E. polyanthemos, but this 
requires further examination, in view of Victorian material available. 
Fniit. That of E. polyanthcmos is turbiuate to semi-ovate with a thin rim, 
cften fissured when quite ripe, the capsule well sunk below the orifice.
