2. With E. asper'a F.v.M. 



It differs from E. aspera in the distribution of the leaves, which are not glaucous and 

 grow upon conspicuous petioles, in the flowers which are crowded on terminal panicles, and perhaps 

 in the fruits. (Original description.) 



Compare figs. 7, 8, Plate 152 (E. aspera), a species imperfectly known, even yet. 

 It is a small tree with smooth bark ; E. Torelliana is a tall, shaft-like tree. So far as 

 we know, E. aspera remains in the homoblastic stage. The fruits of E. aspera are 

 papery or Angophora-like ; those of E. Torelliana are urceolate, and more akin to the 

 Corymb osas. 



3. With E. latifolia R.Br. 



Our new species differs from E. latifolia in the indument, leaves which are not glaucescent, 

 smaller flowers, which are fewer on the peduncle. (Original description.) 



Figures of E. latifolia are not yet published, and a fuller comparison will be 

 given when that species is depicted. But it may be at once stated that the two species 

 are very dissimilar ; the leaves of E. latifolia are always broad, and the fruits scarcely 

 urceolate, and with long, slender peduncles and pedicels. 



4. With E. peltata F.v.M. 



Perhaps E. peltata will require to be placed nearest to E. Torelliana, although the latter 

 stands on record as one of the tallest forest trees near Rockingham Bay, with "a bark smooth as 

 glass " ; moreover the hairiness of its branchlets and leaf stalks is more conspicuous, all its leaves 

 are of completely basal insertion and evidently paler beneath, therefore their stomata are not 

 isogenous but heterogenous; the flowers and fruits may also prove different, the former being only 

 as yet known in an unexpended state, and the latter having never been yet collected at all. 

 ("EucalyptogTaphia," under E. peltata.) 



First we must compare the figures of E. Torelliana with those of E. peltata, which 

 are not published yet. But it may be at once pointed out that the former is a tall 

 shaft-like Gum of coastal areas, while the latter is a yellow-barked Bloodwood of inland 

 regions of low rainfall. Both have peltate juvenile leaves, more or less besprinkled 

 with hairs ; E. peltata has opercula more pointed, longer in comparison with the calyx- 

 tube, with fruits different in shape, and sometimes ovoid. 



5. With E. maculata Hook. 



But it seems that the closest affinity of E. Torelliana is with this species, or 

 at all events these two species have considerable resemblance externally. Both are 

 Gums, but E. maculata displays a greater tendency to branch than E. Torelliana, that 

 is to say, it is less shaft-like. Its bark is practically smooth to the ground, while 

 E. Torelliana has usually a good deal of rough bark, and is a denizen of rich soil and 

 sheltered situations ; E. maculata flourishes under hard conditions, like the Ironbarks. 

 They have affinities in juvenile leaves, the buds may be a good deal similar, though 

 those of E. maculata may be more pediceltate, but the fruits are very different ; both 

 are urceolate, but those of E- Torelliana ere spheroidal, with a high shoulder, and 

 sessile.
