Finally tall ; leaves scattered, narrow- or elongate-lanceolar, slightly or sickleshaped-curved, 

 rather paler and not shining beneath, their lateral veins very subtle and numerous, feathery 

 spreading, the circumferential vein almost contiguous to the slightly recurved edge of the leaf, 

 the oil-dots copious and translucent, sometimes much concealed ; umbels paniculated, on slender 

 stalks, with 8 or less very small flowers, the latter provided with thin stalklets of nearly the same 

 or less length ; calyces ovate-pearshaped before expansion, tardily ruptured along the transverse 

 somemhat irregular sutural line ; the lid depressed-hemispherical, not so broad as the tube and 

 several times shorter ; stamens all fertile ; anthers ovate, somewhat truncated, bursting with 

 parallel fissures ; style very short ; stigma but slightly dilated ; fruits rather small, urnshaped- 

 ocatc, slender-stalked, smooth, 3- rarely 2-celled ; their rim very narrow ; valves deltashaped, 

 deeply enclosed ; seeds without any appendage, the sterile much smaller than the fertile seeds. 



Iii poor hilly country, hitherto traced from Moreton-Bay (Bailey) to the Burnett-River 

 (F. v. M.) and the MacKenzie-River (Bowman, O'Shanesy), chiefly iii the sandstone-formation. 



A tree, passing in colonial language as one of the Bloodwood-trees, attaining a height of 80 

 feet with a stem-diameter of 2 feet, but in exposed situations on the tops of hills dwarfed in growth 

 and fruiting already in a shrubby state. Timber pale, flcxuous in fibre. Bark persistent on the 

 branches as well as on the stem, outside greyish-brown, irregularly fissurated and frustular, 

 inside far more woody than fibrous, but not ponderous, pale-brownish. Leaves somewhat shining 

 and darker above ; stomata hypogenous only. Panicles terminal. Lid separating from the tube 

 of the calyx not so much by a clear circumcision as by a fracture, thus often adhering on one 

 point to the tube while the stamens are fully expanded, occasionally of only half the width of the 

 tube, rarely somewhat pyramidal. Filaments white. Anthers dorsifixed. Fruit-calyces some- 

 times less contracted and then truncate-ovate. Seeds not very numerous, the fertile seeds in 

 proportion to the capsular part of the fruit rather large, about 1 line long, ovate, plan-convex, 

 fixed at the centre. 



In this as in some other instances the definition of the species was elaborated from a very 

 limited number of specimens ; to give descriptions their fullest scope they should rest on 

 examinations of trees instituted in the forests of many localities, for which purpose, as a rule, the 

 opportunities arise only in the course of lengthened periods. Thus we are also unacquainted yet 

 with the form of the seedling of this species. 



The specific name of this tree was suggested by the roughness of the bark, conspicuous not 

 less on the branches than on the stem. The timber seems not of leading value, but the tree is 

 eligible, as mentioned by Mr. Bailey, for its shade in dry hot localities. More important in 

 reference to its Kino, this species is pressed on our attention. The analysis of one sample gave us 

 here as much as 73 per cent, of Kino-tannic acid (soluble in water and alcohol and precipitable 

 by acetate of lead out of an acidified solution) ; 18| per cent. Kino-red or allied substance 

 (insoluble in water, but soluble in alcohol) ; 8 per cent, gum and pigment (soluble in water and 

 partly in alcohol, but riot precipitable by acetate of lead). 



The systematic position of the species is in the series of the Bloodwood-trees, to which 

 E. corymbosa, E. terminalis, E. Abergiana and their allies belong, notwithstanding the smallness 

 of its flowers, although in this and some other respects E. trachyphloia approaches E. crebra and
