EUCALYPTUS SANTALIFOLIA. 



E. santalifolia agrees with E. capitellata in the almost total absence of flowerstalklets, but 

 it attains not the size of a large tree, the leaves are smaller, more rigid, of a lighter green, less 

 conspicuously veined and not remarkably inequilateral, the flowers are generally less numerous 

 on each stalk, the calyces are larger with wider tube and longer lid, the stamens not inflesed before 

 expansion, the anthers more cordate than renate and the fruits usually smaller, not to speak of 

 the seedlings of the two species, those of E. capitellata, according to specimens transmitted by 

 the Eev. Dr. Woolls, being star-hairy and producing leaves narrow-lanceolar, though rounded at 

 the base also. 



The drawing in Bonpland's work represents the anthers erroneously as ovate and the fruit in 

 that flat-topped state, in which it more particularly occurs before perfect maturity. The oval 

 shape of the opposite leaves of young plants, well illustrated in the plate, suffices already to 

 distinguish E. diversifolia from E. viminalis, which has narrow seedling-leaves. Moreover 

 E. viminalis attains the height of a moderate and even tall tree, its ultimate branchlets are more 

 slender, the close and more spreading venation of the leaves is nearly that of E. tereticornis, the 

 flowerstalks are usually shorter and thinner, the calyces are not so large, the anthers oval, the 

 valves in proportion to the rim larger though the fruit as a whole is smaller, the sterile seeds are 

 much narrower than the fertile seeds and the latter obtusangular. The cardinal characteristic of 

 E. santalifolia rests in the position of the stamens before their expansion ; then through a simple 

 turn the lower portion of the filaments remains decumbent, whereas the upper part becomes erect, 

 but in no way the filaments are reduplicated. Such peculiar curvature of the stamens, while in 

 bud, is not known to exist in any other species of Eucalyptus, although an approach to such a 

 staminal eestivation is offered by E. Planchoniana. All other species, in which the stamens are 

 not distinctly doubled back in their early state, namely E. gomphocephala, E. Oldfieldii, E. 

 siderophloia, E. tereticornis, E. salmouophloia as well as E. cornuta and its allies, have the 

 filaments in bud either straight or turned differently to those of E. santalifolia. 



The specific name of this species was devised by some resemblance of the leaves to those of 

 Santalum acuminatum and S. persicarium. Prof. Ralph Tate noticed, that E. santalifolia, together 

 with a particular congener, which De CandoUe (prodr. iii. 220) wrongly united with the East- 

 Australian E. cneorifolia (E. stricta Sieb.), constitutes the predominant scrubs of Kangaroo- 

 Island, that the bark is smooth and separates in long and thin shreds, that the species is found 

 chiefly on ancient shell-beaches with fresh water below, and that it does not attain a height above 

 20 feet ; nevertheless with a fruiting specimen, obtained from Guichen-Bay, and to all appearance 

 belonging to E. santalifolia, a note is given, that there the tree rises to 60 feet, such tallness 

 being probably of exceptional occurrence. Bonpland mentions, that this or a closely allied 

 Eucalypt bore fruit as far back as 1813, in the Botanic Garden of Toulon, and he significantly 

 then already added, that the Eucalypts promised to become a new source of richdom to the South 

 of France.
