Arbor glauca mediocris Mallee siurilis, Morrel vel Blackbutt 

 nominata; cortice l?eve, trunci basi lamellis erassis nigris; ligno 

 rubro duro; foliis teneribus sessilibus vel fere sessilibus, lato- 

 lanceolatis, vel fere ovatis; foliis maturis petiolatis, lanceolatis, 

 acuminatis, plerumque circiter 10 cm. Jongis et 2 cm. latis, vena 

 peripherica a margine distincte remota; pedunculis teretibus vel 

 subangularibus 3-9 flores plusve minusve pedicellatos ferentibus; 

 alabastris operculis elongatis (subconstrictis praecipue siccantibus) 

 calycis tubo circiter bis a3quilongis; filamentis subflavis; fructibus 

 urceolatis vel sub-globosis, circiter 8 mm. diametro, valvorum 

 apicibus subulatis exsertis. 



Looked upon by bushmen as the glaucous or Eastern Goldfields 

 form of the "Morrel" ( E. longicornis). Shares the name "Black- 

 butt" with other Western Australian trees. A medium-sized tree, 

 say one foot in diameter (but it may be much smaller, like a 

 Mallee), a White Gum with blotched bark and more or less short 

 flaky ribbons on the trunk, with a little of the roughness at the 

 butt. Colour of timber rich reddish-brown and very tough. A 

 felled tree shows long tough splinters. 



Juvenile leaves glaucous, sessile or very nearly so, broadly lan- 

 ceolate to nearly ovate, say 4 cm. broad by 6 cm. long, secondary 

 veins irregularly pinnate, intramarginal vein distinctly removed 

 from the edge. 



Mature leaves glaucous, petiolate, lanceolate, acuminate, commonly 

 about 10 cm. (4 inches) long, and about 2 cm. at greatest width, 

 covered with fine dots, secondary veins not very distinct, pinnate,, 

 making an angle of about 45° with the distinct midrib, intra- 

 marginal vein distinctly removed from the edge. 



Peduncles terete or slightly angular, each with three to nine 

 more or less pedicellate flowers. 



Buds with elongated opercula about twice as long as the calyx- 

 tube, and which are somewhat constricted, particularly on drying. 

 The calyx-tube sometimes of a lesser diameter than the base of 

 the operculum, particularly on drying.
