EUCALYPTUS MICKOCORYS. 



F. v. M., fragments phytograpliise Australia ii. 50 (1860) ; Bentham, flora Australiensis iii. 212. 



The " "Wangee." Finally very tall ; leaves scattered, narrow- or oftener broad-lanceolar and 

 somewhat sickleshaped, of thin almost papery consistence, most copiously porous or dotted nith 

 oil-glands, paler and opaque beneath ; their veins very fine, numerous and very much spreading, 

 the longitudinal veins mostly near to the edge ; the terminal umbels paniculate, the axillary 

 umbels solitary, each bearing four to nine flowers ; general flowerstalks compressed, but not 

 broadly dilated ; flowerbuds passing rather gradually into their stalklet and with them assuming 

 a clubshaped form ; lid minute, membranous, depressed-hemispherical, hardly pointed, considerably 

 shorter than the tube of the calyx ; stamens inflexed in bud ; outer filaments nith imperfect or 

 mostly without anthers, often thickened towards the summit ; anthers of the perfect stamens very 

 minute, almost hcartshaped, opening by slits ; style very short and thin ; stigma not dilated ; fruit 

 small, truncate-ovate, 3-4-celled, with a narrow rim ; placental axis more than twice as long as 

 broad ; valves deltoid, reaching to near the summit of the fruit or slightly beyond it ; fertile seeds 

 broader and less angular than the sterile seeds, withoiit any membranous appendage. 



Dispersed from the vicinity of Cleveland-Bay (W. Hill) to the Hastings-River (H. Beckler) 

 in forest-country or on arid or even sandy hills along the coast-side of the ranges, descending to 

 their base. 



A tree, attaining very considerable height, although flowering already in a dwarf state, called 

 " \Vaiigee " by the natives of the Richmond-River, but Forest-Mahogany by the local colonists 

 according to Mr. Fawcett, and " Tee " by the tribes on the Brisbane-River according to Mr. Bailey. 

 Bark persistent to the utmost branches, lamellar and fuzzy from interwoven and wavy fibres, 

 wrinkled, not much crackling in fire, soft to the touch. "Wood very durable, also underground, 

 locally much drawn into use for naves, felloes and spokes, adapted also for lasting railway 

 cross-ties. The foliage is evidently rich in volatile oil, and the chemical and technical properties 

 of this oil should be tested. The general figure of the illustration fairly represents the average 

 dimensions of the leaves, flowers and fruits. 



This species pertains to the section of Rliytiphloire of the cortical system, unless the bark 

 should prove so fibrous, as to indicate a transfer of this tree to the Pachyphloia;. Its nearest 

 affinity among the Heterostemones is with E. hffiinastoma, with the small variety of which, namely 

 E. micrantha (Candolle prodrom. syst. nat. regn. veg. iii. 217 ; me"moire des myrtace'es t. 5) it 

 Chares the minuteness of the calyx-lid, from which the specific appellation of E. microcorys was 

 derived ; the bark however is not smooth even on the branches, the leaves are not of equal color 

 on both sides nor shining underneath, besides they are of thinner consistence, while the veins are 

 more spreading and less prominent ; indeed, as pointed out by me nearly twenty years ago, the 

 leaves of E. microcorys resemble much those of the West Australian E. marginata, a species in 

 other respects very different. The fruit of E. microcorys is longer and particularly narrower than 

 that of E. hasmastoma var. micrantha, and its terminal border is neither broad nor depressed. In 

 E. paniculata, which in some respects also approaches E. microcorys, the bark is deeply furrowed 

 and not unfrequently (particularly in trees from the desert) much seceding, the leaves are nearly 

 of equal color on both sides, not very shining above and not or less copiously perforated by oil- 

 pores, the stomata are not confined to the lower page although those of the surface are about six 

 times less in number than those beneath, the flowerbuds are thicker, the lid is much more convex 

 and substantial or even gradually pointed, the anthers are dilated upwards and not broader than
