bris, E. doratoxyla, E. gomphocephala, E. Oldfieldii, E. diversicolor, E. patens, E. rudis, E. 

 foecnnda, E. redunca, E. pachypoda, E. cornuta, E. otcordata, E. occidentalis, E. calophylla- 

 B. ficifolia, B. erythrocorys, E. tetragona. The following are the seven Western species, which 

 extend to the eastern portions of Australia : E. santalifolia, E. gracilis, E. uncinata, E. pyiiformis, 

 E. incrassata, E. oleosa, E. rostrata, the last mentioned being the only one among these not strictly 

 belonging to the scrub-regions of the desert-country. 



It must however be observed, that the limits of the extra- and intratropical vegetation there 

 do not coincide with the line of Capricorn, as towards the coast — at all events — the last of the 

 southern endemic forms of vegetation cease already in the vicinity of the Gascoyne-Kiver (in about 

 25° southern latitude). Future researches may add also to the above list of Eucalypts, especially 

 as a large extent of the vast Western Australian territory is explored as yet not even 

 geographically.
