In 1885 Dr. Woclls (Plants oj New South Wale-, p. 55) departed from the opinion he had so long 

 held as to the claim of the "' Camden Woolly-butt " to be a distinct species, and looked upon it as a form 

 of E. Stuartiana, a statement which could only have been made without due consideration. 



'" E. Stuartiana has a wi ' . _ lew South Wales, being found on the Mittagong Range, the 



hills near Mudgee, and parts of New England. The bark is fibrous and persistent, and it is known by the 

 popular names " Camden Woolly-butt;," " Peppermint."' or "' Stringybark." On young trees the leaves are 

 frequently opposite. It occurs on the Mil . . Range in company with E. amygdalina, and rises to the 

 heig Op. cit.) 



•c-imen of '" Mudgee Peppermi ibelled by Dr. Woolls, is E. Stuartiana, and is not identical 



with '" Camden Woolly-butt " as surmised by liim on the label. This confusion of the two trees probably 

 arose from the mixing of herbarium specimens. Peppermint is a bad name to apply to this tree, and 

 doubtless arose simply from contemplation of its fibrous bark, which somewhat resembles that of some 

 species known as " Peppermint." The leaves of the "" Camdea Woolly-butt " emit no odour of peppermint. 



We name this species in honour of the late Sir William Macarthur, of Camden Park, who appears to 

 have been the first to recognise this particular Woolly-butt as a distinct tree, while he was certainly one 

 of the pioneers in the difficult task of diffusing accurate information in regard to the Eucalypts of New 

 South Wales. 



Vernacular Name. — " Camden Woolly-butt," after the County of Camden, New South Wales; 

 it has. however, been found in the County of Ar?yle also ; in fact it was originally called " Woolly Gum 

 of Argyle." The name " Woolly-butt " or " Woolly Gum " is in reference to the texture of the bark and 

 sapwood. It is not to be confused with the common Woolly-butt of the Sydney district (E. longifolia), 

 the Woolly-butt of the South Coast (E. saligna), or that of the North Coast (Tristania conferta). 



Bark.— Rough, somewhat Box-like, but very woolly. The sapwood also of a woolly texture. 



Timber.— Pale coloured, nearly white. Not a favourite locally as it does not split well and is not 

 durable. Additional notes on the reputed value of this timber have already been given. 



Seedl ino; Leaves. — Linear-lanceolate, slightly cordate, barely stem-clasping, strictly opposite. 



Juvenile Leaves. — Cordate or ovate-acuminate, stem-clasping, sessile and opposite. Bright 

 green in colour; of similar tint on both sides. 



Mature Leaves. — Alternate, narrow, lanceolate, often falcate, thiekish, of equal colour on both 

 sides, "\enation not prominent; intramarginal vein at some distance from edge; veins n<>t springing 

 from the base, pinnate. 



Buds. — Small, the operculum and calyx of approximately equal size, the former but very slightly 

 conical; shining; up to eight in the head but perhaps five on the average. Umbels axillary, with short 

 scarcely flattened stalks, and stalklets absent or nearly so. 



Anthers.— Small, ovoid in shape, opening in longitudinal slits; indexed in bud; apparently all 

 fertile. Stigma slightly dilated, having the appearance flattened on top. 



Fruits. Very small, much smaller than that of E. iS i. Nearly hemispherical, slightly 



dilated at the rim, which is well defined; valves usually three but rarely four, scarcely exserted. Si 

 small, without any appendage. 



The habit of the tree is shown in plate xxxiv, Proc. Linn. Soc. A T .»S.H'., xxxi, 

 (1906), from a phot*. ! Bowral by .Mr. H. Ji. Cambage. 



Mr. H. i.. Smith baa examined the leaves and has written a paper* "On an 

 Eucalyptus oil containing 60 per cent. f Geranyl A This constituent would 



render it important as a perfume, if it could be obtained at a sufficiently low price. I 

 will refer to the I in my " Fore.., Flora of New South Wales."
