Thus we have one purely eastern species {Baileyana), one eastern species {similis) 

 which probably Avill be found further west. Confined to the tropics are tetrodonta, 

 odontocarpa, and lirata. Sub-tropical Western Australia has eudesmioides, cryihrocorys, 

 and tetragona, of which the first two are true west and the last south-west; the first 

 is inland (approaching the coast), the last two are coastal. 



Apparently the largest tree is E. tetrodonta, but E. Baileyana, E. similis and E. 

 lirata are fairly large trees. E. tetragona and E. erythrocorys are tall shrubs or small trees, 

 while E. odontocarpa, of which we know very little, has hitherto only been recorded as 

 a shrub. The branchlets of all are quadrangular. E. Baileyana and E. tetrodonta are 

 more or less fibrous-barked, the former being the more stringy. E. eudesmioides, E. 

 tetragona, and E. erythrocorys are Gums, while E. similis is a Yellow Jacket, and E. lirata 

 may prove to be so. 



The leaves of all are opposite or sub-opposite, thus sho^ving affinity to Angophora, 

 though in the fruits the latter genus more closely resembles the Angophoroidese section 

 of Eucalyptus. The Eudesmiese have interesting affinities, but a fuller discussion of 

 them must be deferred until the affinities of the whole of the species are dealt with. 



E. tetragona stands out because the leaves reek with oil, and because of its 

 glaucousness. 



Speaking generally, the filaments are arranged in four bundles or tend to be so; 

 the filaments are yellowish white or yellow, those of E. erythrocorys being bright primrose 

 yellow, E. Preissiana being the only species that can approach it in this respect. The 

 opercula of E. erythrocorys are unique in that they are shaped like a biretta, and are of 

 a rich carmine-red colour. 



The buds of E. tetrodonta and E. odontocarpa are reminiscent of cloves, the former 

 being the larger. 



The outstanding characters of the fruit are brought out in the table, the huge 

 fruits of E. erythrocorys (the most remarkable species amongst the Eudesmiese) and the 

 smaller globular fruits of E. Baileyana, being perhaps the most striking.
