the above species, being composed almost entirely of Itevo-rotatory 

 pinene. 



Hah. — Barber's Creek (H. Rumsey). 



Eucalyptus dextropinea, sp.nov. 



" Messmate or Stringybark." 



A tree attaining a height of from 60 to 100 feet or higher, and 

 a diameter up to 5 feet. Bark dark or black on the outside, fibrous 

 and longer in the fibre than that of the other species. Branches 

 smooth for a considerable distance down, but this feature varies. 

 Leaves almost identical with those of E. Icf,vopinea of this paper, 

 and i-esembling also those of U. obliqun, L'Her., and E. 

 Maelleriana, A.E H. Young leaves broad, rounded at the base, 

 and very acuminate, opposite or nearly so, on a short petiole, the 

 venation well defined, the intramarginal vein being much removed 

 from the edge. Mature leaves lanceolate, falcate, acuminate, 

 often very obUque, shining on both sides, rather thick, the intra- 

 marginal vein removed from the edge. Umbels axillary with 

 about 8 flowers, peduncle flattened, operculum hemispherical, 

 shortly acuminate. Calyx tube obconical, stalklet 4-6 lines long. 

 Buds longer and larger than those of E. Icevopinea, sp.nov. 



Anthers reniform, connected above by a prominent connective, 

 valves opening by longitudinal slits. Ovary flat-roofed. 



Fruits 4 to 6 lines in diameter, hemispherical, truncate to 

 rounded, occasionally domed, rarely countersunk, valves slightly 

 exserted. 



Hab. — Monga, on granite formation, but in soil that is fairly 

 rich (W. Bauerlen) ; Barljer's Creek, mostly in the gullies (H. 

 Rumsey). 



It is allied in some of its characters to ^. ohliqua, L'Her., viz.: 

 the shape of the mature leaves, venation, buds, and in one joarti- 

 cular form of fruit which has a contracted orifice and countersunk 

 rim, but their sucker leaves are quite distinct, and the fruits are 

 mostly hemispherical and usually with a thickened convex rim The 

 individual fruit figured by Baron von Mueller in his plate of E.
