DESCRIPTION. 



CCCXV. E. Diemenii Ettingshausen. 



{Ante, p. 177.) 



See also Tate, Rept. Horn. Exped., 1896, Part 3, p. 69. Desert Sandstone of 

 South Australia. 



Ettingshausen compares it to E. marginata Sm. and E. corymbosa Sm., a remark- 

 able comparison. It comes from near Emmaville, New South Wales, under basalt. 

 Tate and Watt record it from Arcoona, Central Australia. 



Following is the original description : — 



Sp. Char. — E. foliis coriaceis, petiolatis, lanceolatis, basi acutis, apice acuminatis, integerrimis ; 

 ne.vatione brachidodroma ; nervo primario, prominente; nervis secundariis subangulis 65-75° orientibus, 

 valde approximates fere congestis, tenuibus, subrectis. ne.vo marginali inter se eonjunctis; nervis 

 tertiariis e secundariis extus angulis acutis egredientibus, abbrevatis. 



Obs. — The leaf is smaller and broader than that of the preceding species (E. MitclieUi), not 

 falciform and less narrowed at apex. Its most distinguishing character is that the secondary nerves 

 are very close to one another, and that they quit the primary one at rather acute angles of divergence. 

 From the close secondary nerves the tertiary ones are very much abbreviated, and the reticulation less 

 developed (see Fig. 9a, magnified). Of the living species, Eucalyptus marginata Sieb., and E. corymbosa 

 Smith, correspond to our fossil, the first relating to form and texture, but the second to all the leaf characters.
