DESCRIPTION. 



CCC XVIII. E. Mitch ell i Ettingshausen. 



(Jute. p. 177.) 



Also Tate, Rept. Horn. Exped., 1890, Part 3. p. 09. Desert Sandstone of 



South Australia. 



He compares it as similar to the living E. rudis Endl, and E. scahra Dum. (E. eugenieides 

 Sieb.). and says it " corresponds " to E. oceanica Ung. of the European Tertiary flora. 



The tvpe comes from near Emmaville, New South Wales, in ironstone shale, 

 under basalt. " Certain fragments of leaves appear to have the characters on which 

 Ettingshausen described this species." So Mr. Deane writes on specimens from 

 Mornington, Victoria, figured by him, Plate hi, figs. 5, 0, 7, 8 (Rec. Geol. Surv. Vict., 

 vol. i, Part I. p. 24, 1902). Tate and Watt record it from the Elizabeth Eiver, Central 

 (South) Australia. 



Following is the original descriptidn : — 



Sp. Char. — E. foliis eoriaceis, petiolatis, lanceolatis vel Iineari-lanceolati j , subfalcatis. basi 

 attenuates, a ] . i . ■ < • acuminatis, integerrimis; nervatione brachidodroma : nervo p:imario prominentc; 

 nervis secundariis subangulis 50-60° orientibus, approxiinatis tenuibus subflexuosis, arciibus laqueorum 

 in nervum marginalem confluentibus inter se conjunctis; nervis tertiariis e seeundariiscxtus subangulis 

 acutis egredientibus; reticulo microsynammato. 



Olia. — Tli'- fossil leaves represented in figs. G 7 S doubtless belong to one and the same speeies. 

 They are equal in texture, shape and nervation, and only show fragments of different partsof leaf. The 

 Bpecimen, liy;. 7. exhibits the petiole and the rather narrowed base of leaf, and the specimen, fig. G, shows 

 the lamina of the leaf to be l.nceolatc and falciform. The texture is coriaceous as the above-mentioned 

 specimens, and that of fig. 8, indicate. Borders are untoothed. The nervation represented in fig. 7a 

 (enlarged) is well preserved on all specimens, and exactly shows the type of the Myrtacese. The primary 

 nerve is prominent. The secondary nerves are thin, approximate, somewhat lle.xuous, and joined together 

 by a marginal nerve. The tertiary nerves join the secondary ones in a direction which is oblique to the 

 axis of the leaf. The network consists of minute meshes. The well-preserved specimens, figs. 6 and 7, 

 exhibit fine dots, equally spread over the lamina. When examined through a strong glass they show 

 themselves to be the receptacles corresponding to the oil glandules due to the leaves of Myrtacese, 



A comparison of these fossils to the leaves of the reci > t Myrtacese led me directly to the large genus 



/. ''..</,'< E. rudis Endl., and E. scribra Dum., both living in Australia, possess leaves very similar to our 



g bhe Eosail Bpecies hitherto described, ours i irre ponds to Eucalyptus oceandca CJng. of the 



European Tertiary flora. I ill " rve the decision as to whether both species are to be united or not 



for future inve tigation. 



Now we come to " Beifcrage zur Kenntiiiss dor Krouldlora Au.stralicns," by 

 Dr. Constantin von Ettingshausen, in Denkschriften K. Ahiul. Wissen., Vienna (1895), 

 which contains descriptions of the following new species, viz., E. crelacea (p. 48), 

 E. Davidsoni, Oxleycma, scoliophyUa (p. 49). E. Warraghiana (p. 50). They are all 

 attributed by the author fco the Cretaceous of New South Wales.
