DESCRIPTION. 



CLXIII. E. Parramattensis C. Hall. 



In Proc. Linn. Soc. N.S.W. xxvii, 568, 1912 (1913). 



Following is the original : — 



Arbor mediocris, laevis, 15-30 psd.. ramulis angulatis, teretibusve pendulis; foliis heterophyllaceis,, 

 prirois vel juvenilibus in petioluni contractis, alternis, 7"-9" longis, li" latis, lanceolatis, falcatis; secundis 

 vel inaturis alternis, petiolatis, lanceolatis, nonnunquam falcatis, 5"-6" longis, concoloribus, subcoriaceis, 

 nonmmquani nitidulis; venis promlnulis, veiia media pallida, venis lateralibus nonnihil obliquis, patule 

 ascendentibus, reticulatis, ante marginem unit-is, vena peripherica a margins nonnihil remota ; glandulis 

 oleosis numerosis; pedunculis axillaribus, 4 '"-6"' longis, 4-7 floris ; floribus pedicellatis, operculo 

 hemisphserico, nonnunquam breviter acuminato, 3"'-4'" longo, calycis tubo circa 2'" longo ; fructu hemis- 

 phserico, 3'" lato, margine rotundo, valvis exsertis. 



A medium-sized tree, 15-30 feet high, as far as seen ; branchlets angled or round, drooping, giving 

 the tree a light graceful appearance ; stem 2-2£ feet in diameter. Found growing in a flat, low-lying 

 situation, on poor clay soil, in company with E. hcemastoma. 



Timber. — A pale pink-coloured wood, of little economic value, as far as seen; it is soft, seasons 

 badly, and is attacked by borers in the young trees, so far as known. Perhaps now that the species is 

 differentiated, more favourable specimens may be discovered. 



Bark smooth, whitish or greyish, stripping off in flakes in the autumn, intermediate between 

 the barks of E. hcemastoma and E. punctata, but without the insect-markings of the former. 



Leaves heterophyllaceous. 



Seedling leaves. — Cotyledons very small, obtusely triangular, sometimes slightly emarginate ; 

 first pairs of leaves linear or narrow-lanceolate, obtuse, opposite, decussate, petiolate. 



Primary or juvenile leaves large, up to 7 or 9 inches long and over an inch broad, petiolate, lanceolate, 

 falcate. Secondary or mature leaves lanceolate, sometimes falcate, but smaller than the primary leaves, 

 a uniform dark green colour on both sides, subcoriaceous sometimes shining ; venation moderately well- 

 marked, the reticulations giving a roughish surface ; lateral veins oblique, fairly distant, and having a looping 

 arrangement with the marginal vein, which is clearly defined and fairly removed from the edge ; oil-glands 

 numerous. 



Peduncles axillary, 4-6 lines long, bearing few flowers, 4-7. 



Buds on a short pedicel, l|-2 lines long ; calyx-tuba li lines long ; operculum hemispherical and 

 domed or conical and shortly acuminate, much longer than calyx-tube. 



Fruit hemispherical, 3 lines in diameter, rim rounded to the dome of the ovary or base of valves, 

 which are free from the rim and often recurved. 



In dealing with this species, Dr. Hall has taken cognizance of the seedling in 

 comparison with the form I have hitherto called " juvenile " in this work. I have 

 over 2,000 coloured drawings of seedlings of Eucalypts in various stages, and think 

 it is desirable to devote special chapters of this work to a collective and comparative 

 study of these seedlings, with adventitious leaf-growths.
