same kind of trees. The various species have been classi- 
fied into groups or sections, according to the shape or other 
‘characters of the author. The leaves have also played 
a part in the grouping of the species, but as the juvenile \ 
stage of development is so different to the adult, and as ; 
the adult leaves are so variable even on the same tree, it 
is nof an easy matter to identify any given tree. 
: The bark has also been used in a popular way as a 
means of identification, but this again is so variable in its 
character as to be of ‘little use in grouping even closely 
allied species. The character of the fruits seems to be 
the most natural, and the old saying, ‘“‘By their fruits 
ye shall know them,’’ seems in the case of the Hucalypts 
to be perhaps the most useful single means of identifi- 
cation. A series of individual fruits of the corymbose 
section shows very clearly how the different species, as 
calophylla, ficifolia, corymbosa; eximia, maculata, are 
closely related to one another, and that these can‘ be iden- 
tified from their individual fruits when typical mature 
fruits are used. 
BarEcKEA virgata, Andr—A_ species which might 
readily be mistaken for a Leptospermum, as its large 
white flowers simulate those of the latter genus. The im- 
pression created by this superficial resemblance is further 
accentuated by the size of the leaves, which are larger 
than those usually found in the New South Wales mem- 
bers of the genus. It is a brush-forest habitue. a lover 
of shade and moisture (hygrophyte), and may be collected 
in the deep mountain gorges at Leura, Wentworth Falls, 
ete., and in the rich forest lands of Southern Illawarra.
