DESCRIPTION. 



CCCXVL E. Hayi Ettingshausen. 



(Ante, p. 177.) 



E. resinifera Sm. and E. pilularis Sm. " show a striking similarity in leaf -formation." 

 Emmaville, New South Wales, in brown carbonaceous clay, below basalt. 



Following is the original description : — 



Sp. Char. — E. foliis coriaceis, petiolatis, lanceolatis, utrinque attenuatis, integerrirnis ; nervatione 

 brachidodroma; nervis secundariis subangulis 30-40° orientibus, approximatis, tenuibus, flexuosis 

 nervo marginali inter se conjunctis; nervi; tertiariis e secundariis extus angulis variis acutis obtusisque 

 egredientibus, inter se conjunctis. 



Obs. — This species is different from the others here described in its secondary and tertiary 

 nerves. The former are more flexuous, and diverge from the primary at more acute angles, the 

 latter, varying in their angles of divergence, arc unequal in their course, longitudinal and transversal 

 intermixed, especially on the forepart of the leaf. The network partly preserved on the specimen, Fig. 5, 

 is represented in Fig. 5a, slightly enlarged, and consists of irregularly-edged meshes. 



DESCRIPTION. 



CCCXVII. E. Houtmanni Ettingshausen. 



(Ante, p. 177.) 



The author compares it with E. Mitchelli and E. Diemenii. It " corresponds to 

 E. Haidingeri Ett., of the European Tertiary flora, and to E. robusta Sm., of the living 

 flora." 



Found in the Emmaville district, New South Wales, in brown carbonaceous 

 clay, below basalt. 



Deane (Rec. Geol. Surv. Vict., vol. i, Part I, p. 24, Plate iv, fig. 1) doubtfully 

 refers a leaf from the deposits at Berwick, Victoria, to this species. He points out 

 the differences from Ettingshausen's type. 



Following is the original description : — 



Sp. Char. — E. foliis coriaceis, late lanceolatis, utrinque angustatis, integerrirnis; nervatione 

 brachidodroma; nervo primario firmo, prominente; nervis secundariis subangulis 65-75° orientibus, 

 approximatis, tenuibus, subflexuosis, nervo marginali inter se conjunctis; nervis tertiariis vix conspicuis. 



Obs. — Differs from the other Eucalypti described here by its larger and broader leaf. Besides, this 

 species deviates from Eucalyptus Mitchelli by the secondary nerves diverging at more obtuse angles, arid 

 from E. Diemenii by the more distant secondary nerves. The nervation is represented in Fig. 3A, enlarged.
