614 ON THE EUCALYPTS OF N.S.W., PART VI., 



And, speaking generally, E. conica is glabrous while E. polyan- 

 thema is more or less glaucous. 



E. AGGREGATA, sp.nOV. 



(Plate xlix.) 



An umbrageous tree, probably worthy of cultivation in cold, 

 damp situations, for ornamental purposes. 



Local names. — "Peppermint" at Wallerawang, probably 

 because of the fibrous appearance of the bark. Known as 

 " Plooded Gum " in most districts, an exception to the usual rule 

 in Australia to limit the term " Gum " to those species of 

 Eucalypts having smooth or nearly smooth barks. It has been 

 called both " Sally " and " Messmate " in the Crookwell district; 

 while it is known as " Black Gum " at Pagan's Ci'eek, according 

 to Mr. Bauerlen. 



Bark. — Box-like or rather more tiaky; between that of a Box 

 and a Stringybark or Woollybutt; cuts woolly. The trunk, large 

 and small branches are all rough; the ultimate branchlets alone 

 being smooth. \\\ old trees very thick and containing essential 

 oil. 



Timber. — White and tough when fresh, but the trunk is 

 usually not straight enough and large enough, as a general rule, 

 for marketable timber; reckoned worthless for standing in the 

 ground. 



Young leaves. — Quite glabrous ; oval to nearly oblong; strictly 

 opposite up to an inch long ; the margins undulate; mucronate 

 with a short point. Young trees are often eaten down by cattle. 



Mature leaves. — Foliage semi-pendulous, lanceolate in shape; 

 usually symmetrical, but oblique leaves not rare ; undulate ; 

 equally green on both sides, scarcely shining ; on the average 

 probably 4^ inches long by 1 broad. Intramarginal vein con- 

 siderably removed from the edge; other veins few but conspicuous; 

 very oblique.
