504 ErCALYPTS OF THE COUNTY OF CUMBEBLAND, 



justly remarks, in reference to it, '' tliat we can best distinguisli 

 JE. paniculata from E. mleroiMoia by the less deei3ly furrowed 

 bark, by the frequent difference in the coloration of the leaf -pages, 

 by the shorter calyx-lids, the sterility of the outer stamens, the 

 infraction of all filaments while in bud, the terminal openings of 

 the anthers, and the dilated stigm.a and perfectly enclosed fruit- 

 valves." Though nearly allied, however, the two trees stand in 

 different sections under the artificial system. 



2. E. sideroiMoia, is the ''broad leaved*' or rough Ironbark, 

 one of the strongest and most durable of colonial timbers, and 

 originally called E. resinifera, because from it the Botany Bay 

 kino was procured very plentifully. The popular names of this 

 species are very confusing, as the term '' broad leaved " is equally 

 applicable to some forms of E. paniculata, whilst thatof ''Eed 

 Ironbark" is more suttable for E. crehra, as that species is more 

 uniform in the colour of its wood There are two forms of E. 

 sideropliloia, varying in the size of the leaves, flowers, and fruit, 

 and particularly in the length of the operculum. In the form, 

 which Mr. "Bentham ragards as typical of the species, the leaves 

 are sometimes lanceolate and somewhat falcate, the operculum 

 conical and rather longer than the calyx-tube, the fruit seldom 

 exceeding two lines, and the valves scarcely protruding. This 

 form seems to include a tree common in some parts of the country 

 and growing in company with the typical E. sideropliloia, but 

 called ''Black Box" and "Ironbark Box." Mr. T. Shepherd, 

 who for many years past has paid attention to our Eucalypts, 

 states "that the wood of the Black Box is so like that of the 

 common Ironbark that it may easily be mistaken for it ; but it is 

 not the least like the wood of the common Box. The saplings at 

 first sight are very like the Box, but the upper branches, unlike 

 those of the Box, have rough bark extending almost to their 

 extremities. When you strip off a piece of the bark, you find 

 that, after a minute or two, the juice, on exposure to the air, turns 

 red like that of Ironbark, whilst that of the Box remains a
