Following is the original description of E. Marsdeni : — 



" Arbor 30-50' altitudine, cortice fibroso inferne superne lsevi foliis petiolatis, lanceolatis, acuminatis, 

 falcatis, obliquis, fere niernbraneis ; cymis axillaribus; pedunculis 4'" longis, pedicellis 11'"; operculo 

 hemisphasrico, umbonato; fructibus hernisphsericis, valvis paruni exsertis." 



A tree, 30 feet high in specimen observed, and probably would attain a height of 60-80 feet when 

 fully grown. 



Seedling. — Cotyledons very small, orbioular-reniform, entire purplish on under-surface, glabrous. 

 Leaves opposite, decussate, obtu3e, shortly petiolate, lanceolate, venation pinnate, rather oblique, edges 

 sinuate. Stem reddish, and both it and the leaves covered with fine, stellate hairs. 



Juvenile leaves of a more advanced stage than in the small seedling are alternate, petiolate, narrow- 

 lanceolate, acuminate, glabrous. Mature leaves alternate, petiolate, falcate, acuminate, oblique, greyish 

 on drying, almost membranous, occasionally shiny, and having a pleasant, aromatic scent. LaminaB 

 6 inch-8 inch long by f inch broad, petiole slender, -J- inch long. Lateral veins oblique, alternately fine, 

 intramarginal vein fairly distant from the edge. 



Inflorescence axillary, peduncles \ i n °h long, with rather few flowers in head, six to nine ; buds 

 turbinate, 5 inches long, operculum hemispherical, shortly acuminate. Stamens all fertile, anthers 

 kidney-shaped. Fruits hemispherical 3 lines in diameter, rim domed, valves small, slightly exserted. 



Bark of an unusual character for a Eucalypt. While it falls in the group of the stringybarks, yet 

 it is laminated, with a sort of ochreous deposit on the surface of each layer. Inner bark very hard and 

 compact. But while the trunk and lower branches have such bark, that of the upper branches and branchlets 

 is smooth and greyish, so that the tree is really a half bark. 



Timber light brown in colour, fairly heavy, close, straight in the grain, annual rings prominent in 

 the young stage, planes and dresses well, and should be usef ul for technical purposes ; gum-veins few. 



RANGE. 



Confined to the County of Cumberland, New South Wales, so far as we know at 

 present. 



The type of E. Penrithensis came from two miles east of Penrith, New South 

 Wales. Guided by Mr. Boorman I saw the tree a month or two afterwards, but it and 

 a few others, believed to be the same, were cut down a short time subsequently, and 

 others could not be traced. 



Toongabbie, New South Wales, at the rear of the Public School, on the Wiana- 

 matta clay, is the only locality known of the type of E. Marsdeni, but I understand 

 from Dr. Hall that his specimen cannot be found now, having probably shared the 

 same fate as the type tree of E. Penrithensis. 



See also notes at pp. 236 and 237 (under E. eugenioides) in Part VII of the 

 present work, 



It will probably turn out that E. Penrithensis is not as rare as was at once 

 supposed. It has probably been passed over as a ragged, hard Stringybark, and 

 looked upon as an anomalous E, eugenioides.
