EUCALYPTUS WATSONIANA. 



brown and tough ; that from the bark of E. macrorrhyncha and E. melliodora darker still than 

 that of the preceding three ; that from the bark of E. obliqua red-brown in color. 



Quality of timber as yet unascertained. 



The relationship of this tree is with E. maculata (which species ias latterly been traced to the 

 neighborhood of the Genoa-Eiver by Mr. Eeader), but the bark is totally persistent, the leaves are 

 frequently a great deal broader, while their veins are finer and not quite so close, the flowers are 

 often fewer and always conspicuously larger, the lid is ampler than the summit of the calyx-tube 

 and seems to be simple from the commencement, although it exhibits considerable thickness ; the 

 fruits are of much larger size, rather expanded than contracted at the summit, with a flatter not 

 suddenly quite descending rim, which latter is separated by a conspicuous circular channel from 

 the tube of the fruit-calyx, while the seeds are larger and the fertile of these more angular. 



Nearer still is the affinity to B. eximia, which has likewise persistent and structurally similar 

 bark, also a subtle venation of the leaves and comparatively large fruits ; but the leaves show the 

 narrowness of those of E. maculata ; so also the calyces have much the structure of the latter 

 species, although they are deprived of stalklets, whereas the fruit bears close resemblance to that 

 of E. corymbosa, a species otherwise very different, belonging to the series with hypogenous 

 stomata and having smaller flowers with neither dilated nor polished lid. E. Abergiana might in 

 these comparisons be left out of consideration, as it has stomata only on the lower page of the 

 leaves, no flower-stalklets and the lid separating from the tube of the calyx by irregular rupture, 

 a narrower fruit-rim and appendiculated seeds. 



Explanation of Analytic Details. — 1, an unexpanded flower, the lid lifted ; 2, longitudinal section of an 

 unexpanded flower ; 3, some stamens in situ ; 4 and 5, front- and back-view of an anther with portion of its 

 filament ; 6, style and stigma ; 7 and 8, longitudinal and transverse section of fruit ; 9 and 10, fertile and sterile 

 seeds ; 11, embryo in situ ; 12, transverse section of the same ; 13, embryo unfolded, to show the cotyledons and 

 radicle ; 14, portion of a leaf ; all magnified, but to various extent.
